Unit
Feedback pulses from the servo motor encoder are counted and displayed.
When the count exceeds ±999, it starts from 0.
pulse
Negative value is indicated by the lit decimal points in the upper two digits.
Press the "SET" button to reset the display value to zero.
The internal counter subtracts 500000000 when the number exceeds
1000 pulses
2000000000. The internal counter adds 500000000 when the number exceeds -
2000000000.
The servo motor speed is displayed.
10 r/min Negative value is indicated by the lit decimal points in the upper two digits.
Displayed in increments of 10 r/min.
The servo motor speed is displayed.
r/min
Negative value is indicated by the lit decimal points in the upper two digits.
The number of droop pulses in the deviation counter is displayed.
pulse
When the count exceeds ±999, it starts from 0.
The value displayed is not multiplied by the electronic gear (CMX/CDV).
1000 pulses
Negative value is indicated by the lit decimal points in the upper two digits.
pulse
Not used with the positioning mode. "0" is always displayed.

The instantaneous torque is displayed.
%
The torque generated is displayed in real time, with the rated torque being 100%.
Position within one revolution is displayed in encoder pulses.
pulse When the count exceeds 999, it starts from 0.
When the servo motor rotates in the CCW direction, the value is added.
The within one-revolution position is displayed in 1000 pulse increments of the
encoder.
1000 pulses
When the count exceeds 999, it starts from 0.
When the servo motor rotates in the CCW direction, the value is added.
The within one-revolution position is displayed in 1000000 pulse increments of the
encoder.
1000000 pulses
