8.4 Speed response selection
Select the motor response in reaction to the command speed using the basic function switch (SW1-No.1).
Setting to the high response mode (ON) can achieve quick motor response.
Setting to the regenerative power suppression mode (OFF) can slow the motor response and suppress the occurrence
of the regenerative power.
Setting range: OFF (Regenerative power suppression mode)
ON (High response mode)
Factory setting: OFF (Regenerative power suppression mode)

Note
•
Turn on the main power supply again after switching the basic function switch (SW1-No.1). If the control
power supply is connected, also turn on the control power supply again.
•
When using the electromagnetic brake type motor in vertical drive such as elevating equipment, set the
basic function switch to the high response mode (ON).
8.5 Two-speed operation
Operation can be performed at two speeds through use of both the internal potentiometer and external
potentiometer (external DC voltage).
When the M0 input is ON, the motor rotates at the speed set with the external potentiometer or external DC voltage.
When the M0 input is OFF, the motor rotates at the speed set with the internal potentiometer.
