TMCM-3314, TMCM-3315 Hardware Manual (V1.00 / 2018-APR-30) 4

2 Features

The TMCM-3314 / TMCM-3315 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-3314 and EtherCAT™ together with USB (Micro-USB) on the TMCM-3315 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
