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.
