5.3 TMCM-6212 + TMCM-6213 Driver Brick
The driver brick of the TMCM-6212 and TMCM-6213 offers two outputs for bipolar stepper motors with up-to 1.1A
RMS / 1.5A peak motor current (programmable), separate HOME + REFL and REFR inputs and encoder inputs (for
incremental ABN encoders with differential signals) for each motor axes. Please note that due to sharing of
hardware resources either REFL and REFR inputs or encoder inputs are available at a given point in time and may
be used. The TMCM-6212 and TMCM-6213 offer three such driver bricks, supporting 6 stepper motors altogether.

5.3.1 Motor connector
As there are two bipolar stepper motors supported per single driver brick there are also two motor connectors
per brick.
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.
