Setting method using the operation panel
The rotation speed can be set while rotating the motor, and it can also be set in the motor standstill state.
This section explains how to set the rotation speed while rotating the motor as an example.
Example: Set the rotation speed to 1000 r/min from 0 r/min

The determined rotation speed is written to the
operation data which is selected based on a combination
of ON/OFF status of the M0 and M1 inputs.
Rotation speed:
0 r/min (Initial value)

If the rotation speed is already set, the motor rotates.
(The gure shows an example of sink logic)
If both the FWD input and REV input are turned OFF, the rotation speed can be set in a state of motor standstill.
Setting method
Remote setting method
The rotation speed can also be set remotely by the following two methods.
Set the "external speed command input" parameter to "ON (enable)" (initial value: OFF), and turn the M0 input and M1 input OFF.
Refer to p.27 for how to set the parameter.
Setting with external potentiometer (accessory)
Connect the external potentiometer to the CN4.
Turning the external potentiometer in the
clockwise direction increases the speed.
"External speed command voltage selection"
parameter:
“0-5” (initial value)
The gure and characteristics are an example
when the external potentiometer
PAVR2-20K
(accessory) is used.

Setting with external DC voltage
Connect an external DC power supply (0 to 5 VDC
or 0 to 10 VDC) with reinforced insulation on its
primary and secondary sides to the CN4.
"External speed command voltage selection"
parameter:
"0 - 5" (initial value) for 0 to 5 VDC

Note
Be sure to set the external DC voltage to 10 VDC or lower. When connecting the external DC power supply, make sure
the polarities are correct. If the polarities are reversed, the speed controller may be damaged.
