Faults / Alarms
Fault
No.
Cause as a function of fault value
(r047.001, r949.001 or r949.009 with acknowledged error)
F022 External fault 2
(active in all operating states)
Bit 26 in control word 2 was in the log. "0" state for longer than the time set in P360 index 002
F023 Fault message from free function block FB2
(active in all operating states)
Fault value:
1 the binector wired via parameter U100 Index.001 is in the state log."1"
2 the binector wired via parameter U100 Index.002 is in the state log."1"
3 the binector wired via parameter U100 Index.003 is in the state log."1"
4 the binector wired via parameter U100 Index.004 is in the state log."1"
F024 Fault message from free function block FB3
(active in all operating states)
Fault value:
1 the binector wired via parameter U101 Index.001 is in the state log."1"
2 the binector wired via parameter U101 Index.002 is in the state log."1"
3 the binector wired via parameter U101 Index.003 is in the state log."1"
4 the binector wired via parameter U101 Index.004 is in the state log."1"
10.1.2.4 Fault messages from motor sensors
F025 Brush length too short
(active in operating states of ≤ o3)
When parameter P495=2 (binary sensing of brush length), fault message at log."0" signal (longer than 10s) at terminal 211
Possible fault causes
♦ Encoder for brush length has responded
♦ Open circuit in encoder cable
F026 Bearings in bad condition
(active in operating states of ≤ o6)
When parameter P496=2 (bearing condition sensing) fault message at log. "1" signal (longer than 2 s) at terminal 212
Possible fault causes
♦ Encoder for bearing condition has responded
F027 Air-flow monitoring of motor fan
(active in operating states of < o6)
When parameter P497=2 (air-flow monitoring), fault message at log "0" signal (longer than 40s) at terminal 213
Possible fault causes
♦ Encoder for fan monitoring has responded
♦ Open circuit in encoder cable
F028 Motor overtemperature
(active in operating states of ≤ o6)
When parameter P498=2 (thermostat connected), fault message at log. "0" signal (longer than 10s) at terminal 214
Possible fault causes
♦ Thermostat for monitoring motor temperature has responded
♦ Open circuit in encoder cable
F029 Motor overtemperature
(active in all operating states)
Select via P493=2 or 3 (temperature sensor at terminals 22 / 23) or
P494=2 or 3 (temperature sensor at terminals 204 / 205)
When parameter P490.01=1 (KTY84 at terminals 22 / 23) or P490.02=1 (KTY84 at terminals 204 / 205):
The fault message is activated if the motor temperature reaches or exceeds the value set in parameter P492.
When parameter P490.01=2, 3, 4 or 5 (PTC thermistor at terminals 22 / 23) or P490.02=2, 3, 4 or 5 (PTC thermistor at terminals
204/ 205):
The fault message is activated if the motor temperature reaches or exceeds the response value of the selected PTC thermistor.
Fault value:
1 Fault activation through temperature sensor at terminals 22 / 23
2 Fault activation through temperature sensor at terminals 204 / 205
