Test Operation - Mitsubishi Electric MELSERVO-J4 Instruction Manual

6. HOW TO USE INDEXER

6.1.3 Test operation

Before starting actual operation, perform test operation to make sure that the machine operates normally.
Refer to section 6.1.1 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 indexer
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 3.8, 3.9, and "MR-J4-
_A_(-RJ) Servo Amplifier Instruction Manual" section 4.5.9.
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) To rotate the servo motor, turn on ST1 (Forward rotation start) in the
manual operation mode with the controller. Set a low speed to [Pr. PT13]
at first, make the servo motor operate, and check the rotation direction of
the motor, etc. If the machine 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) To rotate the servo motor, turn on ST1 (Forward rotation start) in the
manual operation mode with the controller. Set a low speed to [Pr. PT13]
at first, make the servo motor operate, and check the operation 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.
4) Next, check automatic operation from the controller.
