5.1.1 Power supply requirements

The power supply should be designed in a way, that it supplies the nominal motor voltage at the desired

maximum motor current. In no case shall the supply voltage exceed the upper or lower voltage limits. To be

able to cope with high voltage spikes which might be caused by energy fed back from the motor during

deceleration, a sufficient power supply capacitor should be added on the baseboard closed to the module.

Depending on the motor and expected motor current please use a 4700µF or larger capacitor with suitable

voltage rating. Additionally, a suitable suppressor (zener-) diode might be useful.
