Maybe a bad encoder/vane sensor? I would try a new learn trip first, before I change the encoder/vane sensor.....

Error ID: 1501 Message ID: 05DD
NameShort Inv Car Pos
NameLong Invalid Car Position
ErrorGroup 1500_1999_Travel_Control_Ext
SourceID Identification number of the source code file
Description The actual car position read from the position encoder is not in the range of the learnt floor/stop positions (1m above the top floor / 1m below the bottom floor).

The monitoring is not active when a learn trip is needed or is being performed. It is not reported with active montage (JMOF on). The error is surpressed during active acceptance testing, since some of the tests require the elevator to move beyond the normally acceptable range [extreme floors +/- 1meter]. On systems with incremental position tachos this error is not reported.
OEM error category Safety
Extra Info Actual car position (decimal value in [mm]) when the error occurred.

ID Cause Action
1 Car position encoder was moved (without car) while not connected to control or with power down (AGSI) Do a learn trip
2 Car position encoder was replaced Do a learn trip
3 Car position encoder faulty Replace encoder and do a learn trip

ErrorGroup 1500_1999_Travel_Control_Ext
SourceID Identification number of source file
Description The software calculates a difference of the car position values for two consecutive readings (read cycle: 10msec) which exceeds a travel distance of 240mm. After 5 consecutive wrong reading cycles the software logs the error: the elevator performs an emergency stop and is blocked permanent.

This monitoring limits the 'change rate' of the readings from the position tacho and prevents that the software calculates wrong a false floor position (or speed) for the car. The limit value of 240mm is independent of the car speed (240mm is less than the foreseen minimum floor distance). The limit distance is not adjustable.
OEM error category Safety
Extra Info Value of position tacho [increments]

ID Cause Action
1 EMC problems with car position encoder (absolute encoder) Check wiring of car position encoder
2 Faulty car position encoder Replace encoder
3 Faulty wiring of car position encoder Check wiring and connectors

NameShort InvFlPosTrp
NameLong Invalid Floor Position during Trip
ErrorGroup 1500_1999_Travel_Control_Ext
SourceID Identification of the source code file
Description Inconsistent floor position found during a trip. The error is logged when:
a.) the software detects no related floor signal (e.g. hardware input KUET/KUET2) at a car position for which a floor/stop was detected during the learn trip;
b.) the software sees the input for the floor/stop detection (e.g. KUET/KUET2) switching at a car position not related to a position found during the learn trip.

The monitoring is disabled:
- when a learn trip is needed or is being performed.
- with active montage (JMOF on).
- when the mains switch JH is off

On systems with incremental position tachos this error is not reported when the car position is unknown and during a 'sync trip' .
OEM error category Safety
Extra Info Actual car position (decimal value in [mm]) when the error occurred.

ID Cause Action
1 Missing floor magnet or floor vane (KUET/KUET2). Check the hardware in the hoistway.
2 Faulty input on interface board for KUET/KUET2. Check/replace the interface board.
3 Mechanical problem with fixation of floor vane. Check fixation of vane(s).
