12. WHEN USING WITH A GENERAL-PURPOSE INTERFACE
(c) Assigning recommended I/O devices
Assign recommended I/O devices to the pins of CN3 in accordance with each section of point table
method and indexer method.
(d) Other parameter settings
Set the parameters according to the structure and specifications of the machine. Refer to chapter 4
for details.
After setting the parameters, turn off the power as necessary. Then switch power on again to enable
the parameter values.
(3) Servo-on
Enable the servo-on with the following procedure.
(a) Turn on the power.
(b) Switch on SON (Servo-on).
When the servo-on status is enabled, the servo amplifier is ready to operate and the servo motor is
locked.
(4) Power-off
(a) Switch off ST1 (Forward rotation start) and ST2 (Reverse rotation start).
(b) Switch off SON (Servo-on).
(c) Turn off the power.
(5) Homing
Always perform home position return before starting positioning operation.
(6) Stop
If any of the following situations occurs, the servo amplifier suspends and stops the operation of the
servo motor.
Turn off SON (Servo-on) after the servo motor has stopped, and then switch the power off.
Refer to section 3.10 in "MR-JE-_C Servo Amplifier Instruction Manual" for the servo motor with an
electromagnetic brake.
Operation and command
Alarm occurrence
Servo-off command
EM2 (Forced stop 2) off
Servo amplifier
LSP (Forward rotation
stroke end) off or LSN
(Reverse rotation stroke
end) off
Note. Refer to "MELSERVO-JE Servo Amplifier Instruction Manual (Troubleshooting)" for details of alarms and warnings.
The servo motor decelerates to a stop. With some alarms; however, the dynamic brake
operates to stop the servo motor. (Note)
The base circuit is shut off, and the servo motor coasts.
The servo motor decelerates to a stop. [AL. E6 Servo forced stop warning] occurs. In
the torque control mode, EM2 functions the same as EM1.
The servo motor stops immediately and will be servo locked. Operation in the opposite
direction is possible.
