The current position from the machine home position of 0
mm
is displayed.
The position data in the point table or the preset
mm
command position is displayed.
During operation, the remaining distance from the
mm current position to the command position is displayed.
During a stop, the next feed distance is displayed.
The point table No. being executed is displayed.
Feedback pulses from the servo motor encoder are
counted and displayed.
pulse
When the value exceeds 9999999, it returns to zero.
Press the "SET" button to reset the display value to zero.
The servo motor speed is displayed.
r r/min " " is added to the speed of the servo motor rotating in
the reverse direction
The number of droop pulses in the deviation counter is
displayed.
pulse " " is added to the droop pulses in the reverse direction.
The displayed number of pulses is not yet multiplied by
the electronic gear value.
The override setting is displayed.
%
100% is displayed when override is invalid.
V The voltage of the analog torque limit (TLA) is displayed.
The ratio of regenerative power to permissible
L %
regenerative power is displayed in %.
The continuous effective load torque is displayed.
J % Rated torque is defined as 100% and the effective value
for the past 15 seconds is displayed.
The peak torque is displayed.
b % Rated torque is defined as 100% and the peak torque for
the past 15 seconds is displayed.
Position within one revolution is displayed in terms of
encoder pulses.
When the value exceeds the maximum number of pulses,
Cy pulse it returns to 0.
The servo amplifier display shows the 4 lower digits of
the actual within one-revolution position.
It is incremented by CCW rotation.
Moving distance from the home position in the absolute
position detection system is displayed in terms of the
LS rev absolute position detector's counter value.
Because of 4-digit indication, the servo amplifier display
shows the 4 lower digits of the actual ABS counter value.
The estimated ratio of the load inertia moment to the
dC Times
servo motor shaft inertia moment is displayed.
