
20.9 Resolver ABS backup
All models of the BA-C axis AC servomotor include a resolver ABS. The power is driven by a
battery to enable constant monitoring of motor operation even when the power supply to the
controller is cut off and to allow smooth startup without returning to the origin when starting
the system and recovering from an emergency stop.
NOTE
If the setting of
“Setting of encoder type” (refer to section 13.4.14) is “Incremental
encoder
”, the absolute function does not operate even if the battery is connected.
