8. HOW TO USE INDEXER

8.1 Startup

8.1.1 Test operation

Before starting an actual operation, perform a test operation to make sure that the machine operates
normally.
Refer to section 3.1 for how to power on and off the servo amplifier.
Test operation of the servo motor
alone in JOG operation of test
operation mode
Jog mode (jg) of the servo motor
alone in test operation mode
Test operation with the servo
motor and machine connected
Operation using the indexer method
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 correctly rotates at the slowest
speed possible. For the test operation mode, refer to section 4.7 of the "MR-
JE-_C Servo Amplifier Instruction Manual".
In this step, confirm that the servo motor rotates correctly at the slowest
speed in the JOG mode (jg).
Make sure that the servo motor rotates in the following procedure.
1) Issue the Enable Operation command from Controlword (6040h) by
turning on EM2 (Forced stop 2). 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 "-100" is set in Modes of operation (6060h) by the controller, and
bit 4 of Controlword (6040h) is turned on in the Jog mode (jg), the servo
motor rotates At first, set the Profile velocity (6081h) to low speed, then
operate the servo motor, and check the rotation direction of the servo
motor.
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) Issue the Enable Operation command from Controlword (6040h) by
turning on EM2 (Forced stop 2). 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 "-100" is set in Modes of operation (6060h) by the controller, and
bit 4 of Controlword (6040h) is turned on in the Jog mode (jg), the servo
motor rotates At first, set the Profile velocity (6081h) to low speed, then
operate the servo motor, and check the operation direction of the
machine. 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 the indexer operation from the controller.
