Test operation
Before starting actual operation, perform a test operation to make sure that the machine operates normally. Refer to the
following for the power on and off methods of the servo amplifier.
• If necessary, verify the master station (controller) program by using motor-less operation. Refer to the
following for the motor-less operation.
Page 53 Motor-less operation in controller
• Refer to the following for connection via a network.
4.5
Test operation mode
• The content described in this section indicates that the servo amplifier and a personal computer are directly
connected.
• The test operation mode with an Ethernet connection can be used with servo amplifiers with software
version A4 or later and MR Configurator2 with software version 1.70Y or later.
With a personal computer and MR Configurator2, you can execute JOG operation, positioning operation, output signal forced
output, and program operation.
Step
Description
1.
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. Refer to the following for the test operation
mode.
2.
Test operation of the servo motor alone by
commands
In this step, confirm that the servo motor rotates correctly with the commands from the
master station (controller).
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.
3.
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 master station (controller).
Give a low-speed command at first and check the operation direction, etc. of the machine.
If the servo motor 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 master station (controller).
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.
