15.7.4 Use of servo motor with electromagnetic brake
The timing charts at power on/off and servo-on (SON) on/off are given below.
Preset " 1 " in parameter No. 1 to make the electromagnetic brake interlock (MBR) usable. When the
ABS transfer mode is ON, the electromagnetic brake interlock (MBR) 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).
