Servo Transient Transmission Function - Mitsubishi Electric MELSERVO-J4 Series Instruction Manual

Servo transient transmission function

The servo transient transmission function is used to monitor data in the servo amplifier with the servo system controller. In the
servo transient transmission function, the following data can be monitored by setting Index, Sub Index, and Data Type for
each command.
For details of usage, the unit of data types, and others, refer to RD77GF Simple Motion Module User's Manual.

Description
The encoder resolution is displayed.
When the linear servo motor is connected, the virtual resolution
per revolution is returned. When the fully closed loop system is
used, the number of load-side pulses per servo motor-side
revolution is returned.
For rotary type, for example, when an encoder of 4194304
pulse/rev is connected, the object value is 4194304.
The value is always 0 except for rotary type.
The number of characters of the servo amplifier name (N) is
displayed.
The servo amplifier name is displayed.
The number of characters of the servo amplifier software
version (N) is displayed.
The software version of the servo amplifier is displayed.
The cumulative time after power on of the servo amplifier is
displayed.
is displayed.
The alarm history/detail #1 to #16 are displayed. (Hexadecimal)
The alarm occurrence time #1 to #16 are displayed.
(Hexadecimal)
The voltage of main circuit converter (between P+ and N-) is
displayed.
The ratio of regenerative power to permissible regenerative
power is displayed in %.
The continuous effective load current is displayed.
The effective value is displayed considering a rated current as
100%.
The maximum torque generated is displayed.
The highest value in the past 15 s is displayed, with the rated
torque being 100%.
The set ratio of the load inertia moment to the servo motor shaft
inertia moment is displayed.
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 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 module power consumption is displayed. (16 bit version)
The positive value is displayed in power running. The negative
value is displayed in regeneration.
The module integral power consumption is displayed.
