App. 13 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, the unit of data types, and others, refer to the manuals for servo system controllers.

The continuous effective load current is displayed.
The effective value is displayed considering a rated current as 100%.
The ratio of regenerative power to permissible regenerative power is displayed in %.
The maximum torque generated is displayed.
The highest value in the past 15 s is displayed, with the rated torque being 100%.
Feedback pulses from the servo motor encoder are counted and displayed.
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.
The rotation amount of the servo motor is displayed. The value is counted up by one per
servo motor revolution.
The set ratio of the load inertia moment to the servo motor shaft inertia moment is
displayed.
The load to mass of the linear servo motor primary-side ratio is displayed.
The model loop gain value is displayed.
The voltage of main circuit converter (between P+ and N-) is displayed.
The cumulative current value of the servo motor is displayed.
The servo motor speed is displayed.
The linear servo motor speed is displayed at linear servo motor driving.
The droop pulse set in [Pr. PE10] is displayed.
The module power consumption is displayed.
The positive value is displayed in power running. The negative value is displayed in
regeneration.
The module integral power consumption is displayed.
The instantaneous torque is displayed.
The value of torque being occurred is displayed in real time considering a rated torque as
100%.
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%.
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.
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.
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.
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.
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.
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.
