4. HOW TO USE THE POINT TABLE
4 - 2
4.1 Startup
4.1.1 Power on and off procedures
When the servo amplifier is powered on for the first time, the control mode is set to position control mode.
(Refer to section 4.2.1 of "MR-J4-_A_(-RJ) Servo Amplifier Instruction Manual".)
This section provides a case where the servo amplifier is powered on after setting the positioning mode.
(1) Power-on
Switch power on in the following procedure. Always follow this procedure at power-on.
1) Switch off SON (Servo-on).
2) Make sure that ST1 (Forward rotation start) and ST2 (Reverse rotation start) are off.
3) Switch on the main circuit power supply and control circuit power supply.
The display shows "PoS" ("PSL" for MR-J4-03A6-RJ servo amplifiers), and in 2 s later, shows
data.
MR-J4-_A_-RJ 100 W or more
MR-J4-03A6-RJ
(2) Power-off
1) Switch off ST1 (Forward rotation start) and ST2 (Reverse rotation start).
2) Switch off SON (Servo-on).
3) Switch off the main circuit power supply and control circuit power supply.
4.1.2 Stop
If any of the following situations occurs, the servo amplifier suspends the running of the servo motor and
brings it to a stop.
Refer to section 3.10 of "MR-J4-_A_(-RJ) Servo Amplifier Instruction Manual" for the servo motor with an
electromagnetic brake.
Operation/command Stopping
condition
SON (Servo-on) off
The base circuit is shut off and the servo motor coasts.
Alarm occurrence
The servo motor decelerates to a stop with the command. With some alarms,
however, the dynamic brake operates to bring the servo motor to a stop. (Refer to
chapter 8. (Note 1))
EM2 (Forced stop 2) off
The servo motor decelerates to a stop with the command. [AL. E6 Servo forced stop
warning] occurs. Refer to section 2.3 for EM1.
STO (STO1, STO2) off (Note 2)
The base circuit is shut off and the dynamic brake operates to bring the servo motor to
a stop.
LSP (Forward rotation stroke end) off, LSN
(Reverse rotation stroke end) off
It will bring the motor to a sudden stop and make it servo-locked. It can be run in the
opposite direction.
Note 1. Only a list of alarms and warnings is listed in chapter 8. Refer to "MELSERVO-J4 Servo Amplifier Instruction Manual
(Troubleshooting)" for details of alarms and warnings.
2. MR-J4-03A6-RJ servo amplifiers are not compatible with the STO function.
