4. STARTUP
4 - 5
(6) Servo-on
Enable the servo-on with the following procedure.
(a) Switch on the main and control circuit power supplies.
(b) Transmit the servo-on command from the master station (controller).
When the servo-on status is enabled, the servo amplifier is ready to operate and the servo motor is
locked.
(7) Home position return
Always perform home position return before starting positioning operation. (Refer to section 6.1.)
(8) 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.
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 (Note
2)
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.
(Note 1)
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.
Note 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".
