The setting method for each operation data number can be changed using the
MEXE02
.
If the external analog setting device/PWM signal input is selected in the setting method, you can switch whether to set
with the analog setting device (external potentiometer, external DC voltage) or the PWM signal input externally using
the parameter.
Change the setting method using the
MEXE02
while operation is stopped.

VR1 and VR2
Internal potentiometers VR1 and VR2 are used when the rotation
speed is not changed frequently or is set without providing an
external setting device. Adjust the potentiometer using an insulated
screwdriver.
Factory setting: 0 r/min

External potentiometer
An external potentiometer is used when the speed is set from a place away from the driver.
Use the
PAVR2-20K
(sold separately) for an external potentiometer.
Refer to p.46 when setting the upper limit and lower limit of the rotation speed.
