14. ABSOLUTE POSITION DETECTION SYSTEM
14.8.4 Use of servo motor with a lock
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 driver 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 wiring and sequence program which will cause the electromagnetic brake torque
to be generated by the ABS mode (ABSM) and electromagnetic brake interlock (MBR).
Refer to section
14.8.4 (1) for the external wiring example .
Refer to section 14.9.1 (2) (e), section 14.9.2 (2) (g), section 14.9.3 (2) (g) for the sequence program
example .
