Test Operation - Mitsubishi Electric MELSERVO-J3 Series Manual

5. OPERATION

5.2.3 Test operation

Before starting actual operation, perform test operation to make sure that the machine operates normally.
Refer to section 5.2.1 for the power on and off methods of the servo amplifier.
Test operation of servo motor
alone in JOG operation of test
operation mode
Test operation of servo motor
alone by commands
Test operation with 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 7.7 and
8.5.7 for the test operation mode.
In this step, confirm that the servo motor correctly rotates at the
slowest speed under the commands from the command device.
Make sure that the servo motor rotates in the following
procedure.
1) Switch on the Forced stop (EMG) and Servo-on (RYn0).
When the servo amplifier is put in a servo-on status, the
Ready (RD) switches on.
2) Switch on the Forward rotation stroke end (LSP) or Reverse
rotation stroke end (LSN).
3) When the point table is designated to switch on the forward
rotation start (RYn1) or reverse rotation start (RYn2), the
servo motor starts rotating. Give a low speed command at
first and check the rotation direction, etc. of the servo motor.
If the servo 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 command device.
Make sure that the servo motor rotates in the following
procedure.
1) Switch on the Forced stop (EMG) and Servo-on (RYn0).
When the servo amplifier is put in a servo-on status, the
Ready (RD) switches on.
2) Switch on the Forward rotation stroke end (LSP) or Reverse
rotation stroke end (LSN).
3) When the point table is specified from the command device
and the forward rotation start (RYn1) or reverse rotation start
(RYn2) is turned ON, 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, load ratio, etc.
4) Then, check automatic operation with the program of the
command device.
