DD
Cumulative feedback
pulses
C pulse
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 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.
Servo motor speed/
linear servo motor speed
r r/min
The servo motor speed or linear servo motor speed is displayed.
It is displayed rounding off 0.1 r/min (0.1 mm/s) unit.
Droop pulses E pulse
The number of droop pulses in the deviation counter are 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 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.
Cumulative command
pulses
P pulse Not used with the positioning mode. "0" is always displayed.
Command pulse
frequency
n kpulse/s Not used with the positioning mode. "0" is always displayed.
Analog speed command
voltage
Analog speed limit
voltage
F V
Not used with the positioning mode. An applied voltage to the CN1
connector is displayed.
Analog torque command
voltage
U V
Not used with the positioning mode. An applied voltage to the CN1
connector is displayed.
Analog torque limit
voltage
Voltage of TLA (Analog torque limit) voltage is displayed.
Regenerative load ratio L %
The ratio of regenerative power to permissible regenerative power is
displayed in %.
Effective load ratio J %
The continuous effective load current is displayed.
The effective value in the past 15 s is displayed relative to the rated
current of 100 %.
Peak load ratio b %
The maximum occurrence torque is displayed.
The highest value in the past 15 s is displayed relative to the rated
torque of 100 %.
Instantaneous torque T %
The instantaneous torque is displayed.
The value of torque being occurred is displayed in real time considering
a rated torque as 100%.
Position within
one-revolution
(1 pulse unit)
Cy1 pulse
Position within one revolution is displayed in encoder pulses.
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 five digits.
When the servo motor rotates in the CCW direction, the value is added.
Position within
one-revolution
(1000 pulses unit)
Cy2
1000
pulses
The within one-revolution position is displayed in 1000 pulse
increments of the encoder.
When the servo motor rotates in the CCW direction, the value is added.
ABS counter LS rev
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.
The travel distance from the home position is displayed as load side
multi-revolution counter value in the absolution position detection
system.
Load to motor inertia
ratio
dC Multiplier
The estimated ratio of the load inertia moment to the servo motor shaft
inertia moment is displayed.
Bus voltage Pn V The voltage of main circuit converter (between P+ and N-) is displayed.
Encoder inside
temperature
ETh °C Inside temperature of encoder detected by the encoder is displayed.
