Test Operation - Mitsubishi MR-JE-10A Instruction Manual

4. STARTUP

4.2.3 Test operation

Before starting actual operation, perform test operation to make sure that the machine operates normally.
Refer to section 4.2.1 for how to power on and off the servo amplifier.
Test operation of the servo motor
alone in JOG operation of test
operation mode
Test operation of the servo motor
alone by commands
Test operation with the servo motor
and machine connected
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. Refer to section 4.5.9 for the test operation mode.
In this step, confirm that the servo motor correctly rotates at the slowest
speed 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 a pulse train is input from the controller, the servo motor starts
rotating. Give a low speed command at first and check the rotation
direction, etc. of the servo motor. 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) When a pulse train is input from the controller, the servo motor starts
rotating. Give a low speed command at first and check the operation
direction, etc. of the machine. 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, command pulse frequency, load
ratio, etc.
4) Then, check automatic operation with the program of the controller.
