APPENDIX

App. 9 Optional data monitor function

The optional data monitor function is used to monitor data in the servo amplifier with the servo system
controller. With the optional data monitor, the following data types of registered monitor can be set.
For details of usage, unit of data type, and others, refer to the manuals for servo system controllers.
Data type
Effective load ratio
Regenerative load ratio
Peak load ratio
Position feedback
Encoder position within one revolution
Encoder multiple revolution counter
Load inertia moment ratio
Model loop gain
Main circuit bus voltage
Cumulative current value
Servo motor speed
Module power consumption
Module integral power consumption
Instantaneous torque
Servo motor thermistor temperature
Disturbance torque
Overload alarm margin
Error excessive alarm margin
Settling time
Overshoot amount
Internal temperature of encoder
Servo command value
Torque command
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 model loop gain value is displayed.
The voltage of main circuit converter is displayed.
The cumulative current value of the servo motor is displayed.
The servo motor speed 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 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 margins to the levels which trigger [AL. 50 Overload 1] and [AL. 51 Overload 2] are
displayed in percentage.
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.
The time (Settling time) after command is completed until INP (In-position) turns on is
displayed.
The overshoot amount during position control is displayed in units of encoder pulses.
The internal temperature of encoder is displayed. 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.
The position command from the controller is displayed.
The torque command from the controller is displayed.
