4. OPERATION AND FUNCTIONS
4.1 Startup
Start up the direct drive servo referring to the following procedure.
Absolute position detection system
Execution of installation and wiring
Z-phase pulse of the direct drive motor is turned on
by the JOG operation (Note 1 and 2)
(Note 1) Execution of the magnetic pole detection (Refer to section 4.2)
Absolute position
detection system?
Incremental system
Can you manually turn
on the Z-phase pulse of the direct
drive motor?
Change to the setting not requiring the magnetic
pole detection (Refer to section 4.2.2)
Z-phase pulse of the direct drive
motor is turned on manually (Note 3)
Turn the servo amplifier power
supply off and on (Note 2)
(Note 1) Positioning operation check using the test operation mode
Positioning operation check using the controller (Refer to section 4.3)
Home position return (Refer to the manual of the controller.)
Positioning operation
No
Yes
Perform this procedure once at startup
Note 1. MR Configurator is used.
2. Under the absolute position detection system, always turn on the Z-phase pulse of the direct drive motor while the servo amplifier
power supply is on, then turn the servo amplifier power supply off and on. By turning off and on the power supply, the absolute
position becomes confirmed. Without this operation, the absolute position cannot be regained properly, and a warning will occur at
the controller side.
3. If the Z-phase pulse of the direct drive motor can be turned on manually, it does not have to be turned on by the magnetic pole
detection or the JOG operation.
For this operation, always connect the direct drive motor encoder and the servo amplifier and turn on only the control circuit power
supply of the servo amplifier (L
11
, L
21
) (turn off the main circuit power supply L
1
, L
2
, and L
3
). Perform this operation by considering
the safety.
