14. ABSOLUTE POSITION DETECTION SYSTEM 
 
14.9.4 Use of servo motor with an electromagnetic brake 
The timing charts at power on/off and servo-on (SON) on/off are given below. 
Preset parameter No.PA04/PD13 to PD16/PD18 of the servo amplifier to make the electromagnetic brake 
interlock (MBR) valid. When the ABS transfer mode is ON, the electromagnetic brake interlock (MBR) set in 
parameter No.PA04 is used as the ABS data bit 1.  
Hence, make up an external sequence which will cause the electromagnetic brake torque to be generated by 
the ABS mode (ABSM) and electromagnetic brake interlock (MBR).
