Using the Monitor Output
The Servo Drive outputs a monitor voltage proportional to the Servomotor rotation
speed and current from the monitor output connector (CN4) on the top of the Servo Driv-
er. This output can be used to install a meter in the control panel or to enable more pre-
cise gain adjustments.
