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
pulse
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.
The servo motor speed or linear servo motor speed is displayed.
r/min
It is displayed rounding off 0.1 r/min (0.1 mm/s) unit.
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.
pulse
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.
pulse Not used with the positioning mode. "0" is always displayed.
kpulse/s Not used with the positioning mode. "0" is always displayed.
Not used with the positioning mode. An applied voltage to the CN1
V
connector is displayed.
Not used with the positioning mode. An applied voltage to the CN1
connector is displayed.
V
Voltage of TLA (Analog torque limit) voltage is displayed.
The ratio of regenerative power to permissible regenerative power is
%
displayed in %.
The continuous effective load current is displayed.
% The effective value in the past 15 s is displayed relative to the rated
current of 100 %.
The maximum occurrence torque is displayed.
%
The highest value in the past 15 s is displayed relative to the rated
torque of 100 %.
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 is displayed in encoder pulses.
The values in excess of ±99999 can be counted. However, the counter
pulse 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.
The within one-revolution position is displayed in 1000 pulse
1000
increments of the encoder.
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 counter value of the absolution position encoder in the
absolution position detection system.
rev
The travel distance from the home position is displayed as load side
multi-revolution counter value in the absolution position detection
system.
The estimated ratio of the load inertia moment to the servo motor shaft
Multiplier
inertia moment is displayed.
V The voltage of main circuit converter (between P+ and N-) is displayed.
°C Inside temperature of encoder detected by the encoder is displayed.
