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
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.
Test operation of servo motor
alone by commands
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 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 from the controller 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.
Test operation with servo motor
and machine connected
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 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 controller 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
controller.
