14. USING A DIRECT DRIVE MOTOR
14 - 13
14.4.2 Magnetic pole detection
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.
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 Configurator.
(1) Preparation for the magnetic pole detection
POINT
When the test operation mode is selected with the test operation select switch
(SW2-1), the SSCNET communication for the servo amplifier in the test operation
mode and the following servo amplifiers is blocked.
For the magnetic pole detection, use the test operation mode (positioning operation) of MR Configurator.
Turn off the servo amplifier power, and set the test operation select switch (SW2-1) as shown below.
Turning on the power enables the test operation mode.
