Description
The servo motor speed is displayed.
The servo motor torque is displayed with current value.
The value of torque being occurred is displayed in real time considering a rated torque as 100%.
This indicates current command applying to the servo motor.
This indicates the number of droop pulses in the deviation counter per pulse.
This indicates the number of droop pulses in the deviation counter per 100 pulses.
This indicates speed command applying to the servo motor.
This indicates bus voltage at the converter of the servo amplifier.
The continuous effective load torque is displayed. This indicates effective value for past 15
seconds.
The travel distance from the home position is displayed as multi-revolution counter value of the
absolution position encoder in the absolution position detection system.
Position within one revolution is displayed in encoder pulses.
This indicates the number of cumulative errors during a communication with the encoder.
