Using an external potentiometer
An external potentiometer is used to set the speed.
Use the
PAVR2-20K
(sold separately) for an external potentiometer.
Setting range: 0, 80 to 3150 r/min

Using external DC voltage
External DC voltage is used when the speed is set from an external control device.
For the external DC voltage, use a DC power supply (0 to 5 VDC, 1 mA or more) with reinforced insulation on its primary
and secondary sides.
Setting range: 0, 80 to 3150 r/min

Using PWM signal input
The rotation speed is set by inputting the PWM signal.
The rotation speed varies according to the duty cycle of input PWM signals.
Setting range: 0, 80 to 3150 r/min
