Using an external potentiometer
When the torque limiting value is set using an external potentiometer, use the
PAVR2-20K
(sold separately).
Setting range: 0 to 200%

Using external DC voltage
Use when the torque limiting value is set by DC voltage 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 to 200%

Using PWM signal input
Set the torque limiting value by inputting the PWM signal.
The torque limiting value changes according to the duty cycle of input PWM signal.
