6. DISPLAY AND OPERATION

6.2.2 Status display list

The following table lists the servo statuses that may be shown:
Refer to Appendix 2 for the measurement point.

Description

Display

range

Cumulative feedback
pulses

C

pulse

Feedback pulses from the servo motor encoder are counted and
displayed. The value in excess of 99999 is counted, bus since the
servo amplifier display is five digits, it shows the lower five digits of
the actual value. Press the "SET" button to reset the display value to
zero.
Reverse rotation is indicated by the lit decimal points in the upper
four digits.

99999

to

99999

Servo motor speed

r

r/min

The servo motor speed is displayed.
The value rounded off is displayed in 0.1r/min.

5400

to

5400

Droop pulses

E

pulse

The number of droop pulses in the deviation counter is displayed.
When the servo motor is rotating in the reverse direction, the
decimal points in the upper four digits are lit.
Since the servo amplifier display is five digits, it shows the lower five
digits of the actual value.
The number of pulses displayed is not yet multiplied by the electronic
gear.

99999

to

99999

Cumulative command
pulses

P

pulse

The position command input pulses are counted and displayed.
As the value displayed is not yet multiplied by the electronic gear
(CMX/CDV), it may not match the indication of the cumulative
feedback pulses.
The value in excess of 99999 is counted, but since the servo
amplifier display is five digits, it shows the lower five digits of the
actual value. Press the "SET" button to reset the display value to
zero. When the servo motor is rotating in the reverse direction, the
decimal points in the upper four digits are lit.

The continuous effective load torque is displayed.
The effective value in the past 15 seconds is displayed relative to the
rated torque of 100%.

0

to

300

Peak load ratio

b

%

The maximum torque generated during acceleration/deceleration, etc.
The highest value in the past 15 seconds is displayed relative to the
rated torque of 100%.

0

to

400

Instantaneous torque

T

%

Torque that occurred instantaneously is displayed.
The value of the torque that occurred is displayed in real time
relative to the rate torque of 100%.

0

to

400

Within one-revolution
position low

Cy1

pulse

Position within one revolution is displayed in encoder pulses.
The value returns to 0 when it exceeds the maximum number of
pulses.
The value is incremented in the CCW direction of rotation.
