Test Operation - Mitsubishi Electric MELSERVO-J4 Series Instruction Manual

4. HOW TO USE THE POINT TABLE

4.1.3 Test operation

Before starting actual operation, perform test operation to make sure that the machine operates normally.
Refer to section 4.1 for how to power on and off the servo amplifier.
Test operation of the servo motor
alone in JOG operation of test
operation mode
Manual operation of the servo motor
alone in test operation mode
Test operation with the servo motor
and machine connected
Automatic operation by
the point table
In this step, confirm that the servo amplifier and servo motor operate
normally.
With the servo motor disconnected from the machine, use the test operation
mode and check whether the servo motor correctly rotates at the slowest
speed. For the test operation mode, refer to section 3.1.8, 3.1.9, 3.2.8, and
3.2.9 in this manual, and section 4.5.9 and 18.5.10 of "MR-J4-_A_(-RJ)
Servo Amplifier Instruction Manual".
In this step, confirm that the servo motor correctly rotates at the slowest
speed in the manual operation mode.
Make sure that the servo motor rotates in the following procedure.
1) Switch on EM2 (Forced stop 2) and SON (Servo-on). When the servo
amplifier is put in a servo-on status, RD (Ready) switches on.
2) Switch on LSP (Forward rotation stroke end) and LSN (Reverse rotation
stroke end).
3) When MD0 (Operation mode selection 1) is switched off from the
controller and ST1 (Forward rotation start) or ST2 (Reverse rotation
start) is switched on in the manual operation mode, the servo motor
starts rotating. Set a low speed to the point table at first, make the servo
motor operate, and check the rotation direction of the motor, etc. If the
motor does not operate in the intended direction, check the input signal.
In this step, connect the servo motor with the machine and confirm that the
machine operates normally under the commands from the controller.
Make sure that the servo motor rotates in the following procedure.
1) Switch on EM2 (Forced stop 2) and SON (Servo-on). When the servo
amplifier is put in a servo-on status, RD (Ready) switches on.
2) Switch on LSP (Forward rotation stroke end) and LSN (Reverse rotation
stroke end).
3) When MD0 (Operation mode selection 1) is switched off from the
controller and ST1 (Forward rotation start) or ST2 (Reverse rotation
start) is switched on in the manual operation mode, the servo motor
starts rotating. Set a low speed to the point table at first, make the servo
motor operate, and check the rotation direction of the machine, etc. If the
machine does not operate in the intended direction, check the input
signal. In the status display, check for any problems of the servo motor
speed, load ratio, etc.
Check automatic operation from the controller.
