15. USING A DIRECT DRIVE MOTOR

15.3.2 Magnetic pole detection

Before the positioning operation of the direct drive motor, make sure to perform the magnetic pole detection.

Before starting up the equipment, perform the test operation (positioning operation) of MR Configurator2.

The magnetic pole detection is not required for the configured absolute position

detection system where the Z-phase pulse of the direct drive motor can be

turned on manually.

For this operation, always connect the direct drive motor encoder and the servo

amplifier and turn on the control circuit power supply of the servo amplifier.

Perform this operation by considering the safety.

When performing a magnetic pole detection without using LSP (Forward rotation

stroke end) and LSN (Reverse rotation stroke end), set [Pr. PL08 Linear servo

motor/DD motor function selection 3] to "_ 1 _ _" to disable LSP and LSN.

Set [Pr. PE47 Torque offset] to "0 (initial value)" before executing the magnetic

pole detection.

For the magnetic pole detection of vertical axis with direct drive motors, refer to

section 2.1 of "Direct Drive Motor Instruction Manual".
