2.2.3 Shaft Auto-tuning
1. Make preparations for shaft auto-tuning.
1) Check that the shaft switches act properly, including nal limit switches, limit switches, slow-
down switches, and leveling sensors.
2) Check that the acting sequence of the leveling sensors is correct.
Generally, one leveling sensor is installed. If multiple leveling sensors are installed, check that
the acting sequence is correct. Take the situation with three sensors as an example:
Acting sequence of sensors at inspection up: up leveling sensor → door zone sensor → down
leveling sensor
Acting sequence of sensors at inspection down: down leveling sensor → door zone sensor →
up leveling sensor
3) Check CANbus communication state. If fault E51 is not reported and the COP indicator on the
MCB is steady ON, it indicates that CANbus communication between the MCB and the CTB
is normal. If CANbus communication is abnormal, rectify fault E51 according to the solution
described in Chapter 9.
4) Set the related parameters.

Shaft auto-tuning is required each time F0-04 is changed. Otherwise, the
elevator running will be abnormal.
