NOTICE
Do not connect or disconnect motor during operation!
Motor cable and mo-
tor inductivity might lead to voltage spikes when the motor is connected / discon-
nected 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 connecting or disconnecting the motor.
