ClearPath All-In-One Servo Systems

Do you stock ClearPath motors?

We stock a semi-finished inventory of ClearPath motors. Your web order triggers the completion of the build and test process. Up to five built-to-order ClearPath motors ship within 3 business days. Please see the Lead Time FAQs for more details.

Do you have ClearPath motors with an integrated brake?

No. We don’t manufacture brakes and we only sell what we make. However, there are quality third party brakes that integrate nicely to our motors. We’ll be happy to guide you to the right option.

Do you offer gearboxes, stages, or other mechanical components?

No. With a few exceptions, like USB cables, we only sell what we manufacture. But we’re happy to help. Having been in business since 1985, we know what complementary products work well and what vendors are good to deal with. So we’ll guide you toward best-in-class options.

What do the LED blink codes mean?

LEDs are visual representations of specific product states (e.g. a specific blink frequency may indicate an operational state, a safety fault, etc). For complete LED documentation, please download the relevant ClearPath user manual.

I need help sizing a motor. Can Teknic help me?

Yes. Just give us a call or send an email and we’ll help guide you in the right direction.

Does Teknic offer demo units?

No, we think there’s a better way to try our products. Given all the options, there are thousands of part numbers. So we offer a money-back guarantee on product that exactly fits your needs. We don’t loan products that sort of do the job and may have been abused by others. Quickly giving you exactly what you need in a brand new product with a money-back guarantee increases your chance of success.

I just received my new ClearPath. Now what?

We hate reading manuals too, so we created a ClearPath “Quick Start” guide in the ClearPath manual. Read this prior to powering up your ClearPath – it will absolutely save you time. To get the most out of your new ClearPath, we strongly suggest reading through the entire ClearPath manual.

Are ClearPath motors steppers or servos?

State-of-the-art servos. In fact, all of Teknic’s motors are closed-loop brushless servo motors. Teknic does not manufacture stepper motors.

Can I access ClearPath's encoder?

All ClearPaths are fully closed loop servos with an integrated encoder. Feedback to your application is not directly from the integrated encoder itself. In a few applications (such as high speed triggering) you may need an external encoder. But in most cases what the ClearPath provides is less complex, more accurate, and offers more complete status information.

For the ClearPath MC and SD lines there is High Level Feedback - or HLFB. Described in the manual in detail, in summary you set the feedback meaning based on what is important to your application. For example, it can be....1) the servo is running at your commanded velocity, 2) your point to point move is done, 3) your contouring application is actively tracking the command within your required accuracy spec, and so on and so forth. In many applications this is superior to encoder output signals because it provides the feedback you want without having to read and translate encoder data plus it tells you the servo's status in a single, optically-isolated output.

The ClearPath SC allows you to see the encoder position via software communication. This will allow you to understand the servo's health and where you are at any point in time by querying the ClearPath for position feedback. This offers robust communication of motor position without encoder lines running back to the application.

What is the resolution of the ClearPath encoder?

The encoder inside fractional horsepower (DC input) ClearPath motors is 12,800 counts per revolution. Inside the integral horsepower (AC input) models is an encoder with 64,000 counts per revolution. Because ClearPath is a servo, this means that the positional repeatability of the motor shaft (when used in a positioning mode) will be one part in 12,800 (1 in 64,000 for integral hp models).

The number of possible positions per revolution that you can set is less than the number of encoder counts per revolution. For example, certain models have a maximum “input resolution” of 800 positions per revolution. For these models, you can command the motor to any one of 800 shaft angles (i.e., every 0.45 degrees), and you will achieve any of these commanded positions with a repeatability of 1/12,800 (0.028 degrees) or 1/64,000 for an integral horsepower model.

“Enhanced” resolution models (those with an “E” immediately after the third hyphen in the part number), have finer input resolution and can be set to as many as 6,400 positions per revolution (32,000 for integral horsepower models). As an aside, there are a number of technical advantages to using an encoder with a higher resolution than the “positional setability” of the motor, but that discussion is beyond the scope of this FAQ.

How do I tune a dual-driven gantry?

Here are two ways to tune MC- and SD-series ClearPath motors that are mounted to the same axis/gantry:

  • Calculate the inertia of the system then divide that by two. Create a mechanical load (such as a fly-wheel) to simulate the divided inertia. Connect one ClearPath to this load and run auto-tune. Once the auto-tuned file is generated, load it into your second ClearPath.
  • Hook up two computers, one to each ClearPath. Then manually tune both motors simultaneously. This requires a thorough understanding of how to tune a Teknic servo system. Contact Teknic for further information.

Note: With dual-driven axes, motors may need to spin opposite of each other to move the load in unison.

Is g-Stop like an S-curve?

No. Traditionally, smoother motion is achieved by smoothing the motion command (or de-tuning the servo, which is a really bad idea). Smoothing the motion profile works, but moves take longer – often much longer. The patented g-Stop “learns” about your mechanics and applies energy where it makes productive motion and removes energy where it produces vibration or ringing. So mechanics run glass smooth, yet far faster than with S-curve trajectories, and faster even than our proprietary jerk- and jerk-derivative limited RAS™ profiles. g-Stop is now available on both ClearPath-SC and ClearPath-MC series. Check out this video for more information: https://www.teknic.com/watch-video/#g-Stop_SC

ClearPath Return Policy

We want you to be able to thoroughly evaluate ClearPath in your application so you can be confident that it meets all your needs. So we’ve extended our return period and made the return condition very liberal.

For up to 9 units returned on any order:

Teknic will give you a full refund (excluding shipping) on up to nine ClearPath motor units on any order as long as they are returned within 90 days of the invoice date. It is okay for the units to have reasonable wear and tear from using them, but they must be returned in their original packaging (or comparably protective packaging) and still be fully functional (i.e., they must still meet their specifications). Up to nine each of any accessory part number may also be returned under the same conditions.

For the 10th or more motors returned on a given order:

The same return policy as above applies except that we will charge a 15% restocking/refurbish fee on these excess returns.


All ClearPath motors, regardless of part number, are summed together to determine the quantity being returned. Accessories are summed together on the basis of unique part numbers (so, for example, you could return nine power cables and nine USB cables without a restocking charge on these eighteen accessory parts).

Once your return is received and inspected (usually within 72 hours of receipt), your refund will be processed and a credit will be automatically applied to your credit card or original method of payment within seven days. Please note that depending on your credit card company, it may take an additional 2-10 business days after your credit is applied for it to post to your account.

Eclipse Digital Servo Drives

What is the Eclipse family power range?

Products range from 24 volts to 300 volts and from under 100 watts to nearly 15,000 watts.

Are the Eclipse and the ClearPath-SDHP pretty much the same thing?

Both use step & direction signals as position/velocity commands. But ClearPath is a fully integrated system (motor, drive, controls, encoder) while Eclipse is a servo drive designed to be connected to a separate motor.

When should I pick a ClearPath-SD series product over an Eclipse/Hudson combo?

If a ClearPath-SD has enough power for the job and the ambient temperature at the motor is not excessive, a ClearPath is typically the better choice because it will cost less and it is fully integrated which will save more money, reduce installation time, and remove cables (and their potential failure opportunities).

When should I pick an Eclipse over a ClearPath-SD?

Select the Eclipse over a ClearPath-SD when you need more power, want to use a third party motor (such as a linear motor), the ambient temperature at the motor is excessive, or if you are highly space-constrained at the actuator.

Hudson BLDC Servo Motors

Are Hudson motors UL/CE?

Yes. In fact, most of Teknic’s products are UL registered and CE certified. We are also RoHS, REACH and Conflict Mineral compliant.

Is the Hudson motor compatible with drives from other companies?

Yes. The Hudson brushless servo motor family comes with an integrated encoder and commutation outputs. Hudsons are compatible with nearly every 6 step, sine wave and vector servo drive. If you are looking to replace a brush or induction motor, please look at our ClearPath family.

Meridian Integrated Controllers

Can Meridian control steppers and other motors?

Yes. And brush motors, B/L servos, linear servos, galvos, voice coils and more.

Is g-Stop like an S-curve?

No. Traditionally, smoother motion is achieved by smoothing the motion command (or de-tuning the servo, which is a really bad idea). Smoothing the motion profile works, but moves take longer – often much longer. The patented g-Stop “learns” about your mechanics and applies energy where it makes productive motion and removes energy where it produces vibration or ringing. So mechanics run glass smooth, yet far faster than with S-curve trajectories, and faster even than our proprietary jerk- and jerk-derivative limited RAS™ profiles. Check out this video: https://www.teknic.com/watch-video/?id=2#g-Stop_Meridian

Are all M-series Meridians compatible?

Yes. To your software, they are the same. So you can exchange a board level device with a panel mount device, or exchange a 24 volt unit for a 300 volt unit and those changes have zero impact on software.

Can I buy a Meridian?

If you’re an OEM that sells hundred or thousands of automated machines annually, it’s a wonderful product. It has vibration suppression technology found nowhere else. It runs on any OS. It doesn’t use the communication network “standard” du jour, so it’ll be available for the long haul. It’s expandable one axis at a time, in a range of sizes and power levels. It comes with a software foundation so you don’t waste time coding basic foundational software (such as error handling routines). It has an intuitive rapid prototyping GUI to allow MEs and EEs to work on subsystems independent from your software engineers. However, there is a learning curve for the OEM and an investment for Teknic’s engineering staff. If together we conclude the Meridian is right for you, there is nothing like it on the market. But for smaller OEMs, large factory floor automation projects, etc. we recommend different Teknic families.

Is Meridian compatible with CAN, EtherCAT, DeviceNet, SERCOS, Modbus, FireWire, CoaXPress, Skilligent, CC-Link, EtherNet/IP, PROFINET, PROFIBUS, etc.?

Yes and no. After 30 years in the motion control business, we’ve seen dozens of “standards” come and go (or die). We also know motion is just one of many subsystems on your machine. So we made the decision to get off the merry-go-round of shifting standards, forced OS changes, etc. We designed Meridian based on two fundamental constructs: 1) Provide uncompromised motion quality. 2) Instead of directly plugging into everything under the sun (and accepting the cost and performance compromises required to do so), we decided to create a system that could happily live alongside any of the above systems. So figure out what you need for vision, process operation, imaging, testing – whatever is at the heart of your machine. Then pick your OS, computer systems, etc. Meridian will sit happily alongside any of that without compromising motion quality or your budget.

Intelligent Power Supplies

How many motors can run from one Teknic supply?

This depends on dozens of mechanical and timing factors. Because much of what is needed for a power calculation is unknown during the design stage, a good rule of thumb is that an IPC-3 can run 3-4 axes and the IPC-5 can run 5-6 axes.

Can I use a switching mode power supply?

Sometimes. A stock switcher has very little peak capacity (beyond its continuous power rating) and can’t handle regenerative energy. Because of these limitations, typically a switcher is only fine in applications with low acceleration and similar peak and average current demands. In all other cases we recommend either a Teknic IPC power supply or a bulk-linear supply from a third party.

Can the IPC-3 and IPC-5 run off either 110 or 220 volts AC?

Yes. Just change the jumper per the manual.

How do I choose a power supply?

Great question. A motor drive is a power converter, so the math is not straightforward. Moreover, the power supply captures regenerative energy from a decelerating motor and applies to it an accelerating motor (or capacitively stores it), reducing energy demands (think hybrid car). Now consider friction, reverse mechanical efficiency, asynchronous motion, etc. and it becomes clear why there’s no easy answer. So here are some good rules of thumb:

1. An IPC-3 is typically good for 3 axes, an IPC-5 for up to 5 or maybe even more.

2. If looking at a 3rd party power supply:

  • Have enough supply voltage to counter the motor’s back voltage (back-EMF) at your max velocity plus enough additional voltage to generate the required current into the resistance of the motor’s windings.
  • You can’t get more power out than you put in. Make sure you have plenty of wattage for the mechanical shaft power you require.
  • For the first machine, order a supply with more power than you think you need and downsize on machine #2 if you can. If you guess low, the return shipping cost alone will swamp out anything you save upfront.
  • If considering a switcher, please see the FAQ on switchers.

Lead Time/Shipping

What is the web order lead time?

For up to 5 units of each part number, we will ship in 3 days or less. For orders greater than 5 units, the remainder will ship within 3 weeks (the first 5 units still ship within 3 days).

Teknic keeps a stock of semi-finished assemblies. Your order is what triggers the final assembly, full test, and shipment of that specific product (which can take up to three business days). This production method allows Teknic to promise a consistent, short lead time for any one of almost a thousand unique part numbers.

What is the lead time for buying products not via the website?

For OEMs buying with a purchase order, the lead time is 4 weeks (a few products are 3 weeks). This allows us to optimize production scheduling to minimize costs and prices.

Can I get a ClearPath in less than 3 days?


Teknic is able to promise that any part number ordered from the web will ship within three business days. We are able to promise this because we keep a stock of semi-finished assemblies. Your order is what triggers the final assembly, full test, and shipment of that specific product. This production method allows Teknic to promise a consistent, short lead time for any one of almost a thousand unique part numbers.

Depending on the exact manufacturing and order details, we may be able to build the order in less than three days. If that's the case, we won't hold off from shipping earlier. We just can't promise to ship anything in less than three business days. (And remember to add the shipping transit time to estimate the actual arrival date of your order.)

*Quantities up to 5 (per part number) will ship within 3 business days (5 business days for international orders). For quantities greater than 5 (per part number), we will ship the first five units within 3 business days and the remainder will ship within 3 weeks.

Can I get the remainder of my ClearPath order in less than 3 weeks?

Probably – in many cases web customers receive the remainder of their orders sooner than the stated 3 week lead time. That said, we can’t guarantee a faster delivery as the additional units go through our standard manufacturing and testing processes (just like our high volume OEM purchase orders).

Why did only 5 of my 8 ClearPath motors ship in 3 days?

For web orders up to 5 units, we complete the build of semi-finished inventory to your order, fully test, and then ship within 3 business days. For quantities above 5 units, the additional units are typically fulfilled in 3 weeks via the full manufacturing process.

Can you ship faster than 4 weeks for non-web orders?

For a specific OEM PO, we may be able to reduce lead time below 4 weeks. Our ability to expedite depends on many factors (component inventory, equipment usage rates, order backlog, etc.). Please call with your specific needs and we’ll examine options and costs.

How do I select the best shipping method for me?

Your order will be shipped within 3 days (for all part numbers for which you are ordering 5 or fewer). We are located in Victor, New York, so you need to add the time it takes to deliver to your shipping address. Here is a map that shows the UPS shipping time from our location to all areas of the USA.


Do you ship orders overseas?

Yes, all of the items on our eCommerce store (ClearPath, ClearPath accessories, and power supplies) can be shipped internationally. Currently, we support shipping to:

Most likely. Please contact Teknic at sales@teknic.com or call us at +1 585 784 7454 and we will find out the best way for you to order Teknic products.

How much will I pay for international shipping?

Your shipping price will depend on the order size, type of products, destination, and shipping speed. This will be shown on the “Shipping Method” page during checkout.


Please note: Some countries charge additional customs fees and carrier charges. Teknic cannot anticipate these costs. Before placing your order, please contact your local customs office to inquire about any fees that you may expect. Teknic will not reimburse you for any additional fees incurred.


For more information, please see the FAQ section "Are there any other charges, such as duties or taxes?"

What are my international shipping options?

All international orders ship using FedEx. We do not offer Overnight or Second Day deliveries for international orders at this time.

How long will it take for my package to ship internationally?

For up to 5 units of each part number, we will ship within 3 to 5 business days. For orders greater then 5 units, the remainder will ship within 3 weeks (the first 5 units still ship within 3 days). We complete the build of semi-finished inventory to your order, fully test, and then ship. No finished product is on the shelf. This way you get exactly what you want, not what we happen to have.


For additional lead time questions, please check out the full “Lead Time/Shipping” FAQ section.

Are there any other charges, such as duties or taxes?

Additional charges are not included in Teknic's shipping charges.


Teknic's international shipping charges include express air transportation, brokerage fees, and clearance entry fees, but your destination country may charge you import duties (tariffs) and/or taxes and other fees for the products you import from Teknic. These charges are not included and must be paid by you upon receipt of your shipment.


Unfortunately, we cannot calculate what your additional charges may be, because customs and taxation policies vary widely from country to country. As a general guideline, the European Union duty rate for ClearPath motors is 2.7%; the global average import duty rate is about 4%; rates of 8-12% are not uncommon; and a few countries are higher. For exact details, please contact your destination’s customs office or visit their official website.

Does Teknic have a distributor or representative in my country?

No, Teknic chose not to use international distributors or representatives (reps). We’ve made this decision for several reasons:


1. In selling exclusively factory direct, this eliminates the cost overhead of a distributor, which we pass directly to you. (These costs can be as high as 40%).
2. Webstore purchases come with direct support from factory-trained engineers that focus exclusively on Teknic products.
3. We designed ClearPath to be an extremely easy-to-use servo, with: automatic tuning, simple software configuration, and extensive online resources.


Are Teknic's products made in the USA?

Yes. All of Teknic’s products are designed, assembled and tested in Victor, New York (near Rochester).

Are Teknic's products tested?

100%. For example, during assembly, a ClearPath motor undergoes over 80 in-process checks, multiple MDQ tests, a completed-motor stress test and two full functional tests.

Can I get a report that shows proof of test?

If your product has a label, it’s been fully tested. A positive test result is lock-stepped with the next manufacturing process (the next manufacturing step is powered down if the previous step failed.) The very final step in the entire process is label creation. A label will not print if the unit does not pass test, so the label is your proof of a passed test.

How can a US-built motor offer this price/performance, and do you offer customized products?

While there’s wizardry in our firmware, there is no magic in making a better motor. We start with better parts (fully-sintered rare earth magnets, NSK or SKF bearings instead of knock-offs, etc.) We designed a custom encoder for superior integration and lower cost. We automated and streamlined our manufacturing systems to keep quality up and unit cost down. And we test every single product at multiple times during the manufacturing process because defects are expensive for everyone.

But there is a catch. We don’t customize. We have many options that cover 95% of the motor applications in our power range. Unfortunately, custom modifications for individual customers can not be reasonably supported by our automated system without a large risk to quality and overall cost. But if you must have a customized motor, contact us and we may be able to recommend another motor manufacturer.


Is Teknic a manufacturer or a distributor?

Teknic is a manufacturer of state of the art servo motion control products.

How long has Teknic been in business?

Teknic has been at the vanguard of the servo control industry since 1985.
