Product Information

Back to top
The TMCM-170 is a controller / driver module for high performance servo drives based on brushless DC motors. It gives a high resolution like a stepper motor coupled with the high dynamic, high velocity and high reliability of a BLDC drive. A built-in ramp generator allows parameterized smooth positioning, with an external switch in order to provide for an absolute position reference. Its small form factor allows direct mounting on or into a motorencoder assembly. The TMCM-170 integrates a position regulator and a ramp generator, to allow for velocity modes. The module can be remote controlled via an RS232, RS485 or via a CAN interface (ordering option).
