Test Operation - Mitsubishi Electric Melservo MR-J3-A 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 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 6.9 for
the test operation mode.
In this step, confirm that the servo motor correctly rotates at the
slowest speed under the commands from the command device.
Make sure that the servo motor rotates in the following
procedure.
1) Switch on the Emergency stop (EMG) and Servo-on (SON).
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 a pulse train is input from the command device, 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 Emergency stop (EMG) and Servo-on (SON).
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 a pulse train is input from the command device, 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
command device.
