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 as an example for how to set the rotation speed while rotating the motor.
Example: Set the rotation speed to 1000 r/min from 0 r/min
24 VDC±10%
150 mA or more

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 figure 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.29 for how to set the parameter.
•
Setting with external potentiometer (supplied or sold separately).
Connect the external potentiometer to the CN4.
Turn the external potentiometer clockwise to
increase the speed.

The gure and characteristics show examples
for when the supplied external potentiometer or
accessory
PAVR-20KZ
(sold separately) 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 to 5" (initial value) for 0 to 5 VDC
"0 to 10" for 0 to 10 VDC
The input impedance between the VM input and
VL input is approximately 11.3 kΩ.

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