Name Description
Motor/load side position The position deviation between the servo motor-side and load-side is
*2
deviation displayed.
This function can be used for fully closed loop control.
The number of pulses is displayed in the load-side encoder unit.
Motor/load side speed The speed deviation between the servo motor-side and load-side is
*2
deviation displayed.
This function can be used for fully closed loop control.
Internal temperature of The internal temperature detected by the encoder is displayed.
encoder For the linear servo motor, "9999" is displayed.
Settling time The period of time (settling time) from the completion of the command to
INP (In-position) on is displayed.
Oscillation detection The frequency at the time of oscillation detection is displayed.
frequency
Number of tough drive The number of times the tough drive function has activated is displayed.
operations
Unit power consumption The unit power consumption is displayed. The positive value is displayed
in power running. The negative value is displayed in regeneration.
Unit total power consumption The unit total power consumption is displayed.
Excessive error alarm The margin for the excessive error alarm trigger level is displayed in the
margin encoder pulse unit. The excessive error alarm is triggered when the
margin is 0 pulse.
Overload alarm margin The margins for the alarm levels of [AL. 050 Overload 1] and [AL. 051
Overload 2] are displayed as a percentage.
Overshoot amount The overshoot amount during position mode is displayed in units of
encoder pulses.
Torque equivalent to The difference between the necessary torque and the actually required
disturbance torque (torque current value) to drive the servo motor is displayed as the
torque equivalent to disturbance.
Current command This indicates the current command applied to the servo motor.
Speed command This indicates the speed command being applied to the servo motor.
In the position mode, the speed command calculated from the position
command and command filter is displayed.
Command speed output 2 The command speed to be used for speed control is displayed as the
command output of the analog monitor.
Torque command The target torque value of the torque command in the torque mode is
displayed. "0" is displayed in the position mode and velocity mode.
Speed limit value The speed limit value in the torque mode is displayed.
"0" is displayed in the position mode and velocity mode.
*1
U-phase current feedback This indicates the U-phase current value applied to the servo motor in
internal units.
*1
V-phase current feedback This indicates the V-phase current value applied to the servo motor in
internal units.
*1
Encoder error counter This indicates the cumulative number of errors during communication with
the encoder.
Load-side encoder error This indicates the cumulative number of errors during communication with
*1
counter the load side encoder.
Operation mode The control modes of the servo amplifier are displayed.
The following shows the value of each control mode.
Position control mode: -20
Speed control mode: -21
Torque control mode: -22
Test operation mode (JOG operation): -1
Test operation mode (Positioning operation): -2
Test operation mode (Output signal (DO) forced output): -4
Test operation mode (Machine analyzer): -6
Droop pulses (model Droop pulses of the deviation counter between a servo motor-side position
position deviation) and a model position are displayed.
*2
Speed command 2 This indicates the speed command being applied to the servo motor.
Droop pulses (command The number of droop pulses in the deviation counter is displayed. The
*2
unit) number of pulses is displayed in the command unit.
