17. SPEED CONTROL OPERATION
17.5.3 Test operation
Before starting an actual operation, perform a test operation to make sure that the machine operates normally.
Refer to section 17.5.1 for how to power on and off the servo amplifier.
Test operation of the 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 rotates correctly at
the slowest speed. Refer to section 7.7 and 8.5.7 for the test operation
mode.
Test operation of the 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 in the servo-on status, the ready (RD) is switched
on.
2) Switch on the forward rotation stroke end (LSP) and the 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 machine does not operate in the intended direction,
check the input signal.
Test operation with the servo motor
and machine connected
In this step, connect the servo motor with the machine and confirm that
the machine operates normally with 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 in the servo-on status, the ready (RD) is switched
on.
2) Switch on the forward rotation stroke end (LSP) and the 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 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) Check automatic operation with the program of the controller.
