** Input power supply must not exceed recommended voltage, or it may damage the GSD1 drive.
Linear power supply can be sized per drive voltage and motor full load current.
Switched power supply should be sized per drive voltage and double the motor full load current.
*** For 0–10 VDC input signal, please refer to

**** Plugging is a method of rapidly changing motor direction by reversing motor armature polarity, while the motor is still
running.
