Parameter Details
8-4 Analog Control Parameters
Explanation of Set Values
Select the speed command when using speed control. The drive has internally set speed function
that can be used to easily achieve speed control by using contact inputs.
For details on internally set speed function, refer to "5-4 Internally Set Speed Control" (P.5-19).
Explanation of Set Values
Set to reverse the polarity of the speed command input (REF: CN1 pin 14). This is used to change
the motor rotation direction without changing the polarity of host device command signals.
The default setting for this parameter is 0. By rotating to the reverse direction with the +command
keeps the compatibility with all OMNUC W-Series Servo Drives.
The operation of the Servomotor may be abnormal if the polarity of the speed command signal from the Position
Control Unit does not agree with the setting of this parameter when the Servo Drive system is comprised of the
combination of the Servo Drive set to the Speed Control Mode and an external Position Control Unit.
