16. INDEXER POSITIONING OPERATION
16.5.3 Test operation
Before starting actual operation, perform test operation to make sure that the machine operates normally.
Refer to section 16.5.1 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 moto
r
operate normally.
With the servo motor disconnected from the machine, use the test
operation mode and check whether the servo motor correctl
y
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 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 start (RYn1)
the servo motor starts rotating. Give a low speed command at
first and check the rotation direction, etc. of the servo motor. I
f
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
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 start (RYn1) 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.
