4. STARTUP
4 - 10
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 how to power on and off the servo amplifier.
POINT
If necessary, verify controller programs by using motor-less operation. Refer to
section 4.5.2 for the motor-less operation.
Test operation of the servo motor
alone in JOG operation of test
operation mode
Test operation of the servo motor
alone by commands
Test operation with the 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.
Give a low speed command 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.
In this step, connect the servo motor with the machine and confirm that the
machine operates normally under the commands from the controller.
Give a low speed command first and check the operation direction, etc. of
the machine. If the machine does not operate in the intended direction,
check the input signal.
Check any problems with the servo motor speed, load ratio, and other status
display items with MR Configurator2.
Then, check automatic operation with the program of the controller.
4.5 Test operation mode
CAUTION
The test operation mode is designed for checking servo operation. It is not for
checking machine operation. Do not use this mode with the machine. Always use
the servo motor alone.
If the servo motor operates abnormally, use EM2 (Forced stop 2) to stop it.
POINT
The content described in this section indicates that the servo amplifier and a
personal computer are directly connected.
By using a personal computer and MR Configurator2, you can execute JOG operation, positioning operation,
output signal forced output, and program operation without connecting the servo system controller.
