CANopen Stepper Motor Controller, It supports the CiA301 and CiA402 sub-protocols
of the CANopen protocol.
UC42 uses the latest 32-bit DSP digital chip and has advanced drive control algorithms and noise
suppression technology to ensure smooth motor operation. Stable, low noise, and temperature controllable.
Users can set any ID address within 1-255 and any current value within 0-8A through the host computer.
Maximum output peak current of the UC42 bus driver is 2.5A.
UC42 can be set to 1-256 subdivisions and adopts built-in micro-subdivision technology, which can achieve
high subdivision effects even under low subdivision conditions, ensuring that the motor operates with uniform
step intervals and no large or small step problems.
3 input signal ports and 2 output signal ports, supporting position, speed, and return-to-origin control modes.
with highest communication rate in 1Mbps.
