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 amplif ier and servo moto
r
operate normally.
With the servo motor disconnected from the mac hine, 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 a t the
slowest speed under the commands from the comm and device.
Make sure that the servo motor rotates in the f ollowing procedure.
1) Switch on the Forced stop (EMG) and Servo-o n (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 th e start (RYn1)
the servo motor starts rotating. Give a low sp eed 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 machin e and confirm
that the machine operates normally under the c ommands from the
command device.
Make sure that the servo motor rotates in the f ollowing procedure.
1) Switch on the Forced stop (EMG) and Servo-o n (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 dev ice 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 operat e
in the intended direction, check the input signal. In t he status
display, check for any problems of the servo m otor speed, load
ratio, etc.
4) Then, check automatic operation with the pro gram of the
command device.
