TMCM-3212, TMCM-3213 Hardware Manual (V0.95 / 2017-MAR-01) 4

2 Features

The TMCM-3212 / TMCM-3213 is a three axes controller/driver module for 2-phase bipolar stepper motors with

separate encoder (differential) and HOME / STOP switch inputs for each axis. CAN, RS485 and USB (Micro-USB)

interfaces are available on the TMCM-3212 and EtherCAT™ together with USB (Micro-USB) on the TMCM-3213 for

communication. Furthermore the modules offer four analog / digital inputs and four digital outputs together with

a brake chopper unit (supporting an external brake resistor) for supply voltage limitation when energy is fed back

into the supply rail.

MAIN CHARACTERISTICS
