LL07 Encoder Synchronization
Determines correct phasing of A/B encoder channels and direction of rotation.
Refer to Encoder Synchronization Section, pg. 72 for procedure.
USER: Run empty car UP on
Inspection Speed
FAILURE: Speeds not correct,
verify encoder
PPR/Signal/Mounting
STATUS: Speed signs don't match,
swapping encoder phases, run the
car UP again
USER: Did the elevator travel UP?
STATUS: Reversing motor
direction, run the car UP again
FAILURE: Encoder error detected,
verify encoder
PPR/Signal/Mounting
FAILURE: Minimum measurement
speed not reached, increase
speed, run the car UP again
SUCCESS: Encoder
synchronization complete
Cannot start tune because another
tune mode is already active
FAILURE: Motor phasing incorrect,
swapping encoder phases, do SPI
