4. HOW TO USE THE POINT TABLE

4.1.3 Test operation
Before starting an actual operation, perform a test operation to make sure that the machine operates
normally.
Refer to section 4.1 for how to power on and off the servo amplifier.
Test operation of the servo
motor alone in JOG operation
of test operation mode
Manual operation of the servo
motor alone in test operation
mode
Test operation with the servo
motor and machine connected
Automatic operation using the
point table
In this step, confirm that the servo amplifier and the 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 at the slowest
speed. For the test operation mode, refer to section 3.1.8 and 3.1.9 in this
manual, and section 4.5.9 of "MR-JE-_A Servo Amplifier Instruction Manual".
In this step, confirm that the servo motor rotates correctly at the slowest
speed in the manual operation mode.
Make sure that the servo motor rotates in the following procedure.
1) Switch on EM2 (Forced stop 2) and SON (Servo-on). When the servo
amplifier is in a servo-on status, RD (Ready) switches on.
2) Switch on LSP (Forward rotation stroke end) and LSN (Reverse rotation
stroke end).
3) When MD0 (Operation mode selection 1) is switched off from the
controller and ST1 (Forward rotation start) or ST2 (Reverse rotation
start) is switched on in the manual operation mode, the servo motor
starts rotating. Set a low speed to the point table at first, operate the
servo motor, and check the rotation direction of the servo motor, etc. 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 with the commands from the controller.
Make sure that the servo motor rotates in the following procedure.
1) Switch on EM2 (Forced stop 2) and SON (Servo-on). When the servo
amplifier is in a servo-on status, RD (Ready) switches on.
2) Switch on LSP (Forward rotation stroke end) and LSN (Reverse rotation
stroke end).
3) When MD0 (Operation mode selection 1) is switched off from the
controller and ST1 (Forward rotation start) or ST2 (Reverse rotation
start) is switched on in the manual operation mode, the servo motor
starts rotating. Set a low speed to the point table at first, operate the
servo motor, and check the rotation direction of the machine, etc. If the
servo motor 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.
Check automatic operation from the controller.
