4. STARTUP
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 m ethods 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 rotat es correctly. Refer to section
4.5 for the test operation mode.
In this step, confirm that the servo motor ro tates correctly under the
commands from the controller.
Make sure that the servo motor rotates in the f ollowing procedure.
Give a low speed command at first and check the rotation d irection, etc. of the
servo motor.
If the servo motor does not operate in the intended direction, check the inp ut
signal.
In this step, connect the servo motor with the machin e and confirm that the
machine operates normally under the commands f rom the command device.
Make sure that the servo motor rotates in the f ollowing procedure.
Give a low speed command at first and check the op eration 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 rat io, etc.
Then, check automatic operation with the program of the command devic e.
