4.4.3 Test operation
Before starting actual operation, perform test operation to make sure that the machine operates normally.
Refer to section 4.4.1 for the power on and off methods of the servo amplifier.
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 correctly rotates at the slowest
speed. Refer to section 4.5.9 for the test operation mode.
In this step, confirm that the servo motor correctly rotates at the slowest
speed under the commands from the controller.
Make sure that the servo motor rotates in the following procedure.
1) Switch on SON (Servo-on). When the servo amplifier is put in a servo-on
status, RD (Ready) switches on.
2) When TC (Analog speed command) is input from the controller and RS1
(Forward rotation start) or RS2 (Reverse rotation start) is switched on,
the servo motor starts rotating. Give a low torque command at 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.
Make sure that the servo motor rotates in the following procedure.
1) Switch on SON (Servo-on). When the servo amplifier is put in a servo-on
status, RD (Ready) switches on.
2) When TC (Analog speed command) is input from the controller and RS1
(Forward rotation start) or RS2 (Reverse rotation start) is switched on,
the servo motor starts rotating. Give a low torque 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, check for any problems of the servo motor speed, load ratio, etc.
3) Then, check automatic operation with the program of the controller.
