4.2 Motor Connector
For the three motors 0. . . 2 there are two connector options: either one detachable screw connector (can
be used with either 12pin or 3x4pin mating connectors) intended for prototyping and smaller series or
three crimp style connectors (Molex KK series) for higher volume / series.
NOTICE
Do not connect or disconnect motor during operation!
Motor cable and mo-
tor 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.
