Indication Status Description
A b
Initializing
Power of the servo amplifier was switched on at the condition that the power of
servo system controller is OFF.
The axis No. set to the servo system controller does not match the axis No. set
with the rotary axis setting switch (SW1) of the servo amplifier.
A servo amplifier fault occurred or an error took place in communication with the
servo system controller. In this case, the indication changes.
"Ab "
"AC " "Ad " "Ab "
The servo system controller is faulty.

4.4 Test operation
Before starting actual operation, perform test operation to make sure that the machine operates normally.
Refer to section 4.2 for the power on and off methods of the servo amplifier.
POINT
If necessary, verify controller program by using motorless operation.
Refer to section 4.5.2 for the motorless operation.
Test operation of servo motor
alone in JOG operation of test
operation mode
Test operation of servo motor
alone by commands
Test operation with servo motor
and machine connected
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. Refer to section
4.5 for the test operation mode.
In this step, confirm that the servo motor rotates correctly under the
commands from the controller.
Make sure that the servo motor rotates in the following procedure.
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.
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.
Give a low speed command at first and check the operation direction, etc. o
f
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, command pulse frequency, load ratio, etc.
Then, check automatic operation with the program of the command device.
