ClearPath SC integrated servo with full software control, C++ class library, Window/Linux, and 16+ axis coordination


ClearPath-SC blends a sophisticated, networked motion controller into the already compact ClearPath all-in-one servo motor system. There is no easier way to get high-performance motion control.

Two models are available: the SK model, which has 2-3 times the power of similar size hybrid step systems; and the HP model, which has the highest amount of power per cubic inch of any servo available today.

Software Features

Feature Description Basic Version
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
Alternative step & direction interface ClearPath-SC's inputs can be configured to accept step and direction (or quadrature A/B) signals like the ClearPath-SD series. But while running in step & direction mode with the SC series, you can also communicate using your own C++ application software to query status or change parameters. check check
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
