15. USING A DIRECT DRIVE MOTOR
15 - 5
15.3.1 Startup procedure
Start up the direct drive servo in the following procedure.
Absolute position detection system
Installation and wiring
Turn on the Z-phase pulse of the
direct drive motor by using the JOG
operation. (Notes 1 and 2)
Execute the magnetic pole detection. (Refer to section 15.3.2.) (Note 1)
Absolute position
detection system?
Incremental system
Can you manually turn
on the Z-phase pulse of the
direct drive motor?
Change the setting to disable the
magnetic pole detection.
(Refer to section 15.3.2.)
Turn on the Z-phase pulse of the
direct drive motor manually. (Note 3)
Turn the servo amplifier power
supply off and on again. (Note 2)
Positioning operation check using the test operation mode (Note 1)
Positioning operation check using the controller (Refer to section 15.3.3.)
Home position return operation (Refer to the controller manual used.)
Positioning operation
No
Yes
Perform this procedure once at startup.
Set [Pr. PA01]. (Refer to section 3.14.)
Note 1. Use MR Configurator2.
2. For the absolute position detection system, always turn on the Z-phase pulse of the direct drive motor while the servo amplifier
power is on, and then turn the servo amplifier power supply off and on again. By turning off and on the power supply, the
absolute position becomes confirmed. Without this operation, the absolute position will not be regained properly, and a
warning will occur at the controller.
3. If the Z-phase pulse of the direct drive motor can be turned on manually, the Z-phase pulse 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 (L11 and L21) (turn off the main circuit power supply L1, L2, and L3). Perform this
operation by considering the safety.
