Home position return
Always perform home position return before starting positioning operation.
Stop
Turn off the servo-on command after the servo motor has stopped, and then switch the power off.
If any of the following situations occurs, the servo amplifier suspends and stops the operation of the servo motor.
Refer to section 3.9 of "MR-J4-_GF_(-RJ) Servo Amplifier Instruction Manual (Motion Mode)" for the servo motor with an
electromagnetic brake.
*1 Refer to "MELSERVO-J4 Servo Amplifier Instruction Manual (Troubleshooting)" for details of alarms and warnings.
*2 If an error occurs, RX (n + 3) F is set to "0".
Operation and command
Stopping condition
Master station (controller)
Servo-off command
The base circuit is shut off, and the servo motor coasts.
Ready-off command
The base circuit is shut off and the dynamic brake operates to stop the
servo motor.
Quick stop command
The servo motor decelerates to a stop.
Error occurrence
The servo motor decelerates to a stop.
Cyclic communication ready command off
The servo motor decelerates to a stop.
Servo amplifier
Alarm occurrence
The servo motor decelerates to a stop. With some alarms; however, the
dynamic brake operates to stop the servo motor.
EM2 (Forced stop 2) off
The servo motor decelerates to a stop. [AL. E6 Servo forced stop warning]
occurs. For EM1, refer to section 3.5 of "MR-J4-_GF_(-RJ) Servo Amplifier
Instruction Manual (Motion Mode)".
LSP (Forward rotation stroke end) off or
LSN (Reverse rotation stroke end) off
The servo motor stops immediately and will be servo locked. Operation in
the opposite direction is possible.
STO (STO1, STO2) off
The base circuit is shut off and the dynamic brake operates to stop the
servo motor.
