7.1 Setting the rotation speed
The rotation speed can be set using the external analog setting device (external potentiometer or external DC voltage)
or VR1.
Whether to use the external analog setting device or VR1 can be selected by switching the ON/OFF status of the M0 input.
The setting range is 100 to 3000 r/min.
