ClearPath® - Integrated Servo System

CPM-SDSK-2341S-ELN

The ClearPath-SD “SK” model is our “Stepper Killer”. This name started as an inside joke, but it is true, so we kept the name. Compared to a stepper, ClearPath is fully closed-loop (can’t lose steps), quiet, and 2 - 3 times the power for less money than a stepper system. (Compare ClearPath prices with any stepper system where the stepper’s maximum power (i.e., its maximum value of torque times speed) is at least one third of that of the ClearPath model you’re comparing.)

Operating Modes

Step and Direction One ClearPath input counts steps from your motion controller, the other input determines if the steps are made in the clockwise or counter-clockwise direction.

ClearPath International Shipping Policies

Teknic ships ClearPath products to a number of selected countries outside of the United States. To see if we currently ship to your country, check the drop-down menu in the “Calculate Shipping Cost” box in the shopping cart or the Country drop-down menus on the Checkout page. Products shipped internationally may take up to two more days to ship due to extra processing time, but we will do our best to ship small quantities within three days.

For more information about Teknic’s international shipping policies and capabilities, please see the International Shipping FAQs page. Additionally, you can fill out our contact form or call us at +1 585 784 7454 for information about our OEM-direct sales channel and other options that may be available to you.

IMPORTANT: Additional charges 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.

The tariff codes for the products available on our website are as follows:

Product Type Harmonized System (HS) Tariff Code

Feature Description Basic Version

Advanced Version
(Optional)
Jerk-limited
positional moves
Make relative or absolute moves with automatic jerk limiting and jerk-derivative limiting for ultra-smooth motion. check check
Velocity moves Ramp up or down to user-selected velocities and rotate continuously. Programmable settings control acceleration, jerk (rate of change of acceleration), and jerk derivative for ultra-smooth changes in speed. check check
Flexible homing routines Home to a limit switch or hardstop (with gentle, torque-limited hardstop detection). User-defined homing routine can be pre-configured and invoked with one line of code. check check
Read measured position, velocity, torque, and much more Full access to real-time status of all motion parameters (more than 30 different status indicators) check check
Safety shutdowns Constant, automatic monitoring of a variety of motor operating conditions, and shutdowns as necessary to prevent motor and/or system damage. check check
Soft limits Set software end-of-motion limits to prevent accidental crashes (can be used simultaneously with physical limit switches). check check
Global torque limiting Programmable limit on the maximum amount of torque. check check
Automatic brake
coil control
Automatically engage a third-party fail-safe brake when an axis shuts down or is disabled. check check
Group shutdowns Automatically stop all motion axes simultaneously when any axis has a problem. Also, a global stop input allows non-programmatic simultaneous stopping of all axes using a digital input, button, or switch. check check
Up to 16 axes per
com port
Using low-cost SC Hub boards ($49), create up to 4 "mini-networks" of up to 4 axes each, which can be daisy-chained (distributed or plugged directly into each other without cables) to allow maximum flexibility and minimal wiring. check check
Robust communication Innovative hardware and communication design allows high command throughput (over 1,000 commands per second) without using noise-sensitive high-speed circuitry or non-deterministic "crash and retry" protocols. All inputs are optically isolated for even more noise immunity. check check
Automatic network configuration No need for setting DIP switches or programming network addresses. Just power up the system and each axis is automatically addressed based on its position in the network. check check
g-Stop™ anti-vibration move profiles Motion profile sculpting based on patented anti-vibration technology. Allows the fastest possible moves without exciting mechanical resonances in the machine. Easy to configure, and robust operation even as mechanics wear over time. See video demonstration. check
Triggered moves One or more axes can be configured to start simultaneously upon command or electronic signal for the most precise synchronization requirements. check
Head-tail moves Create two- or three-part move profiles where the beginning and/or the end of the moves are at a different maximum velocity than the middle part of the moves. This is useful for making fast moves with one or two slower segments (e.g., moving past a camera slowly and then moving to a target quickly, or slowly clamping something at the end of a fast move). check
Asymmetric moves Create move profiles with different acceleration and deceleration limits. Often, because of friction (or gravity), an axis can decelerate faster than it can accelerate, and this feature allows faster moves in these cases. check
Trigger events at user-defined positions Get a notification when an axis reaches a certain position (either after the start or before the end of the move) to allow synchronization with other events or processes. check
Positive/Negative torque limiting Independently limit positive torque and negative torque (typically used in clamping applications). check
Conditional torque limiting Automatically limit torque (positive and/or negative torque) when an axis is in a certain positional zone, or based on an electrical signal, or when a move completes. check
Attention generation Automatically generate interrupts based on user-defined events so that you don't have to constantly poll for them. This creates a more responsive and synchronized system. check
Position capture Precisely capture axis position on-the-fly based on an electronic input. check
