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
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.
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 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.
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 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 or MR Configurator, 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.
