5.3 TMCM-3212 + TMCM-3213 Driver Brick
The driver brick of the TMCM-3212 and TMCM-3213 offers one output for bipolar stepper motors with up-to 3A
RMS / 4.2A peak motor current (programmable), separate HOME + REFL and REFR inputs and encoder inputs (for
incremental ABN encoders with differential signals) for the related motor axis. The TMCM-3212 and TMCM-3213
offer three such driver bricks, supporting 3 stepper motors altogether.

5.3.1 Motor connector
Each motor (with two coils A + B and four connecting wires) can be connected via one 4 pin Molex MicroFit™
connector (Molex part no. 43045-0412). Mating connector housing e.g. Molex 43025-0400, contacts Molex 43030-
0007. Please note that there are alternative options available from Molex for both, mating housing and contacts.
