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 or
disconnect power supply before (dis)connecting the motor.
