7.2.10 Manual Zero Adjustment and Gain Adjustment of
Analog Monitor Output
Motor speed, torque reference, and position error can be monitored through the ana-
log monitor output. Refer to Section 6.5 Analog Monitor.
Use the manual zero adjustment function to compensate for the output voltage drift
or the zero point drift caused by noise entering the monitor system. The gain adjust-
ment function can be changed to match the sensitivity of the measuring system.
Note: The output voltage of the analog monitor is ±8V. The output voltage polarity will be reversed if ±8V
is exceeded.
