Magnetic Pole Detection - Mitsubishi Electric MR-J4-10B(-RJ) Instruction Manual

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.
POINT
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 FLS (Upper stroke
limit) and RLS (Lower stroke limit), set [Pr. PL08 Linear servo motor/DD motor
function selection 3] to "_ 1 _ _" to disable FLS and RLS.
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".
