Data type Description
Main circuit bus voltage The voltage of main circuit converter (between P+ and N-) is displayed.
Regenerative load ratio The ratio of regenerative power to permissible regenerative power is displayed in %.
Effective load ratio The continuous effective load current is displayed.
The effective value is displayed considering a rated current as 100%.
Peak load ratio The maximum torque generated is displayed.
The highest value in the past 15 s is displayed, with the rated torque being 100 %.
Estimate inertia moment ratio The set ratio of the load inertia moment to the servo motor shaft inertia moment is
displayed.
Model loop gain The model loop gain value is displayed.
LED display The value shown on the 7-segment LED display of the servo amplifier is displayed.
Load-side encoder information 1 When an incremental type linear encoder is used for the load-side encoder, the Z-phase
counter of the load-side encoder is displayed by encoder pulses.
When an absolute position type linear encoder is used for the load-side encoder, the
encoder absolute position is displayed.
Load-side encoder information 2 When an incremental type linear encoder is used for the load-side encoder, the display
shows 0.
When an absolute position type linear encoder is used for the load-side encoder, the
display shows 0.
When a rotary encoder is used for the load-side encoder, the display shows the multi-
revolution counter value of the encoder.
Speed feedback The servo motor speed is displayed.
Servo motor thermistor temperature The thermistor temperature is displayed for the servo motor with a thermistor.
For the servo motor without thermistor, "9999" is displayed.
For the servo motor with a thermistor, refer to each servo motor instruction manual.
Z-phase counter The Z-phase counter is displayed in the encoder pulse unit.
For an incremental type linear encoder, the Z-phase counter is displayed. The value is
counted up from 0 based on the home position (reference mark).
For an absolute position type linear encoder, the encoder absolute position is displayed.
Module power consumption The module power consumption is displayed.
The positive value is displayed in power running. The negative value is displayed in
regeneration.
Module integral power consumption The module integral power consumption is displayed.
Disturbance torque The difference between the torque necessary to drive the servo motor and the actually
required torque (Torque current value) is displayed as the disturbance torque.
Instantaneous torque The instantaneous torque is displayed.
The value of torque being occurred is displayed in real time considering a rated torque as
100%.
Overload alarm margin The margins to the levels which trigger [AL. 50 Overload 1] and [AL. 51 Overload 2] are
displayed in percentage.
Error excessive alarm margin The margin to the level which triggers the error excessive alarm is displayed in units of
encoder pulses.
The error excessive alarm occurs at 0 pulses.
Settling time The time (Settling time) after command is completed until INP (In-position) turns on is
displayed.
Overshoot amount The overshoot amount during position control is displayed in units of encoder pulses.
Servo motor side/load-side position
deviation During fully closed loop control, a deviation between servo motor side position and load-
side position is displayed.
The number of pulses displayed is in the load-side encoder pulse unit.
Servo motor side/load-side speed
deviation During fully closed loop control, a deviation between servo motor side speed and load-side
speed is displayed.
Internal temperature of encoder The internal temperature of encoder is displayed. "0" is displayed for the linear servo
motor. When an encoder communication error occurs, the last value will be displayed
before the error.
This is available with servo amplifiers with software version C4 or later.
Machine diagnostic status The current status of the machine diagnostic function is displayed.
Friction estimation data The friction estimation data estimated by the machine diagnostic function is displayed.
Vibration estimation data The vibration estimation data estimated by the machine diagnostic function is displayed.
