4 -  2 

 
4.2 Magnetic pole detection 

POINT  

Magnetic pole detection is not required for the configured absolute position 
detection system where the Z-phase pulse 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. 

 

 
Make sure to perform the magnetic pole detection before starting the positioning operation in order to match the 
positional relationship between the direct drive motor and the encoder. 
Before starting up the equipment, always perform the test operation (positioning operation) of MR Configurator. 
 
4.2.1 Preparation for the magnetic pole detection   

POINT  

When the test operation mode is set with the test operation select switch (SW2-1), 
the SSCNET   communication of the servo amplifiers following the servo amplifier 
with the test operation mode is disconnected. 

 

 
For the magnetic pole detection, the test operation mode (positioning operation) of MR Configurator is used. 
Turn the power of servo amplifier off and set the test operation select switch (SW2-1) as shown below. By 
turning the power on, it switches to the test operation mode.
