POINT
Refer to appendix 4 for the measurement point.
Symbol Unit
Feedback pulses from the servo motor encoder are counted and
CL pulse
displayed.
Press the "SET" button to reset the display value to zero.
Negative values are indicated by the lit decimal points in the upper two
CH 1000pulses
digits.
The servo motor speed is displayed in 10r/min unit.
r 10r/min
The servo motor speed is displayed in r/min unit.
r1 r/min
The number of droop pulses in the deviation counter is displayed.
EL pulse
When the servo motor is rotating in the reverse direction, the decimal
points in the upper two digits are lit.
EH 1000pulses The displayed number of pulses is in the same pulse unit as the servo
motor encoder resolution.
The position command input pulses are counted and displayed.
As the value displayed is not yet multiplied by the electronic gear
PL pulse
(CMX/CDV), it may not match the indication of the cumulative feedback
pulses.
Press the "SET" button to reset the display value to zero.
PH 1000pulses
Reverse rotation is indicated by the lit decimal points in the upper two
digits.
The frequency of the position command input pulses is displayed.
The value displayed is not multiplied by the electronic gear (CMX/CDV).
The value in excess of ±999 can be counted up to ±1500. However, the
n kpps
counter shows only the lower three digits since the servo amplifier
display is three digits.
The ratio of regenerative power to permissible regenerative power is
L %
displayed in %.
The continuous effective load current is displayed.
The effective value in the past 15[s] is displayed relative to the rated
J %
current of 100%.
The maximum current is displayed.
The highest value in the past 15[s] is displayed relative to the rated
b %
current of 100%.
Torque that occurred instantaneously is displayed.
The value of the torque that occurred is displayed in real time relative to
T %
the rate torque of 100%.
Position within one revolution is displayed in encoder pulses.
Cy1 pulse
The value returns to 0 when it exceeds the maximum number of pulses.
The value is incremented in the CCW direction of rotation.
Cy2 1000pulses
The value is decremented in the CW direction of rotation.
Multiplier
The estimated value of the load to motor inertia ratio is displayed.
dC
( 10 )

Status of the bus voltage is displayed in five steps.
5: Overvoltage (About 400V or more)
4: High voltage (About 375V or more)
Pn
3: Normal
2: Low voltage (About 200V or less)
1: Undervoltage (About 160V or less)
Settling time is displayed.
The value in excess of 999 can be counted. However, the counter
ST ms
shows only the lower three digits since the servo amplifier display is
three digits.
