Automatic VC offset
Voltage is automatically offset to stop the servo motor if it does not come to a stop
when VC (Analog speed command) or VLA (Analog speed limit is 0 V. Section
18.5.5
Alarm code output If an alarm has occurred, the corresponding alarm number is outputted in 3-bit code. Chapter 8
Test operation mode
Jog operation, positioning operation, motor-less operation, DO forced output, and
program operation
MR Configurator2 is required for the positioning operation and program operation.
Section

Section
18.5.4
SEMI-F47 function This is not available with MR-J4-03A6 servo amplifier.
Tough drive function
This function makes the equipment to continue operating even under the condition
that an alarm occurs.
MR-J4-03A6 servo amplifier is compatible with vibration tough drive. This is not
compatible with instantaneous power failure tough drive.
Section 7.3.1
Drive recorder function
This function continuously monitors the servo status and records the status transition
before and after an alarm for a fixed period of time. You can check the recorded data
on the drive recorder window on MR Configurator2 by clicking the "Graph" button.
However, the drive recorder will not operate on the following conditions.
1. You are using the graph function of MR Configurator2.
2. You are using the machine analyzer function.
3. [Pr. PF21] is set to "-1".
