Symbol Unit
Feedback pulses from the servo motor encoder are counted and displayed.
The values in excess of ±99999 can be counted. However, the counter shows
only the lower five digits of the actual value since the servo amplifier display is
C pulse
five digits.
Press the "SET" button to reset the display value to zero.
The value of minus is indicated by the lit decimal points in the upper four digits.
The servo motor speed is displayed.
r r/min
It is displayed rounding off 0.1 r/min unit.
The number of droop pulse in the deviation counter is displayed.
The decimal points in the upper four digits are lit for reverse rotation pulses.
The values in excess of ±99999 can be counted. However, the counter shows
E pulse
only the lower five digits of the actual value since the servo amplifier display is
five digits.
The number of pulses displayed is in the encoder pulse unit.
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 values in excess of ±99999 can be counted. However, the counter shows
P pulse only the lower five digits of the actual value since the servo amplifier display is
five digits.
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 frequency of position command input pulses is counted and displayed.
n kpps
The value displayed is not multiplied by the electronic gear (CMX/CDV).
1) Torque control mode
Input voltage of VLA (Analog speed limit) voltage is displayed.
F V
2) Speed control mode
Input voltage of VC (Analog speed command) voltage is displayed
1) Position control mode and speed control mode
Voltage of TLA (Analog torque limit) voltage is displayed.
U V
2) Torque control mode
Voltage of TC (Analog torque command) voltage is displayed.
The ratio of regenerative power to permissible regenerative power is displayed
L %
in %.
The continuous effective load current is displayed.
J %
The effective value in the past 15 s is displayed relative to the rated current of
100 %.
The maximum occurrence torque is displayed.
b %
The highest value in the past 15 s is displayed relative to the rated current of
100 %.
The instantaneous occurrence torque is displayed.
T %
The value of torque being occurred is displayed in real time considering a rated
torque as 100%.
Position within one revolution is displayed in encoder pulses.
The values in excess of ±99999 can be counted. However, the counter shows
Cy1 pulse only the lower five digits of the actual value since the servo amplifier display is
five digits.
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
1000
encoder.
Cy2
pulses
When the servo motor rotates in the CCW direction, the value is added.
The travel distance from the home position is displayed as multi-revolution
LS rev counter value of the absolution position encoder in the absolution position
detection system.
