4 Connectors
The TMCM-1110_V23 stepRocker has nine connectors altogehter. There are two screw connectors for
power and motor and two interface connectors (mini-USB and RS485). Furthermore, the stepRocker has
one connector for reference switches for all three motors, the driver input connector (TTL level) for motor
0, two controller output connectors (TTL level) for motors 1 and 2 and the GPIO connector, which can be
used e.g. for connecting an ABN-encoder.
NOTICE
Start with power supply OFF and do not connect or disconnect motor dur-
ing operation! Motor cable and motor inductivity might lead to voltage spikes
when the motor is (dis)connected while energized. These voltage spikes might
exceed voltage limits of the driver MOSFETs and might permanently damage
them. Therefore, always switch off / disconnect power supply or at least disable
driver stage before connecting / disconnecting motor.
