DRIVE SPEED LIMIT EXCEEDED DURING SAFETYCHAIN BRIDGED
While the car is landing on a floor the signal indicating low speed (typically at
v < 0.3 m/s) coming from the drive frequency converter (open loop) is expected
to change once from inactive to active state. The error occurs if this signal has
changed once to active state and changes back again to inactive state
(meaning: The car speed has increased during landing). Note that the safety
circuit at the door is overbridged at this point of time. Note that the elevator can
get blocked if this error appears too many times within a specific period of time
(typically > 3 times in 1 hour).
C1:See 0407
A1:See 0407
C2:Parameter 'speed limit' is set wrong
A2:Check parameter 'speed limit' at drive frequency converter
C3:Rope slip
A3:Check driving mechanics and traction
C4:See 0407, C2
A4:See 0407, A2

DRIVE MOTOR RESISTOR CONNECTION
At least one of the drive motor resistor connecting devices, used for a smooth
trip start at two speed drives (resistor start-up), does not operate as expected.
C1:Any connecting device feedback signal (typically from contactor,
for example, SWAHA, SWAFA) is faulty
A1:Check general wiring to drive motor resistor/coil connecting devices
C2:Any connecting device (for example, SWAHA, SWAFA) is faulty
(for example, stuck contacts, burned coil of contactor)
A2:Replace corresponding connection device

DRIVE BRAKE MAX RELEVELING THRESHOLD EXCEEDED
Too many consecutive relevelings in the same direction occurred, indicating a
slowly drifting car. A brake capability test is triggered.
0422
DRIVE BRAKE CAPABILITY PERIODIC TEST DELAYED
The brake capability test has been delayed by 8 h due to higher prio services
or due to test conditions not met.
Shall be possible to check the reason of the delayed test:
– Load status ≥ 21 %
– Elevator status not in maintenance
– Traffic status
0423
DRIVE BRAKE CAPABILITY PERIODIC TEST ABORTED
The brake capability test has been postponed by 24 h because:
– Safety chain opened during test
– Internal drive error
– Test timeout
