5.3 TMCM-3314 + TMCM-3315 Driver Brick
The driver brick of the TMCM-3314 and TMCM-3315 includes a single axis motion controller (supporting linear + S-
ramps and closed-loop support with external encoder) and a bipolar stepper motor driver with up-to 7A RMS /
9.6A peak motor current (programmable). It offers dedicated HOME + REFL and REFR inputs and encoder inputs
for incremental ABN encoders with differential signals. The TMCM-3314 and TMCM-3315 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 MiniFit™
connector (Molex part no. 39-28-8040). Mating connector housing e.g. Molex 39-01-2040, contacts Molex 39-00-0039.
Please note that there are alternative options available from Molex for both, mating housing and contacts.
