App. 14 Optional data monitor function
The optional data monitor function is used to monitor data in the servo amplifier with the servo system
controller. In the optional data monitor function, data types of registered monitor and transient command can
be set.
For details of usage, unit of data type, and others, refer to the manuals for servo system controllers.
App. 14.1 Registered monitor
Data type Description
Effective load ratio The continuous effective load current is displayed.
The effective value is displayed considering a rated current as 100%.
Regenerative load ratio The ratio of regenerative power to permissible regenerative power is displayed in %.
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%.
Position feedback Feedback pulses from the servo motor encoder are counted and displayed.
Encoder position within one revolution The position in servo motor-side 1-revolution is displayed in the encoder pulse unit.
When the value exceeds the maximum number of pulses, it resets to 0.
Encoder multiple revolution counter The rotation amount of the servo motor is displayed. The value is counted up by one per
servo motor revolution.
Load inertia moment ratio The set ratio of the load inertia moment to the servo motor shaft inertia moment is
displayed.
Load mass ratio The load to mass of the linear servo motor primary-side ratio is displayed.
Model loop gain The model loop gain value is displayed.
Main circuit bus voltage The voltage of main circuit converter (between P+ and N-) is displayed.
Cumulative current value The cumulative current value of the servo motor is displayed.
Servo motor speed The servo motor speed is displayed.
Servo motor speed The linear servo motor speed is displayed at linear servo motor driving.
Selected droop pulse The droop pulse set in [Pr. PE10] 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.
Instantaneous torque The instantaneous torque is displayed.
The value of torque being occurred is displayed in real time considering a rated torque as
100%.
Instantaneous thrust The instantaneous thrust is displayed at linear servo motor driving.
The value of thrust being occurred is displayed in real time considering a continuous thrust
as 100%.
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.
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.
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.
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.
Disturbance thrust The difference between the thrust necessary to drive the linear servo motor and the
actually required thrust (Thrust current value) is displayed as the disturbance thrust.
