Drive Faults; F030 Commutation Failure Or Overcurrent Has Occurred (Active In Operating States Of – –, I, Ii); F033 Fault Message From Free Function Block Fb4 (Active In All Operating States); F029 Motor Overtemperature (Active In All Operating States) - Siemens 6RA70 Series Instructions Manual

Fault
No.
Cause as a function of fault value
(r047.001, r949.001 or r949.009 with acknowledged error)
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

Drive faults

NOTICE
The monitoring functions F031, F035, F036, and F037 are deactivated in the delivery state.
They can be activated via parameter P820.
F030 Commutation failure or overcurrent has occurred
(active in operating states of – –, I, II)
Possible error causes
♦ Mains voltage dip in regenerative feedback mode
♦ Current control loop not optimized
Fault value:
1 The blocking voltage time area for the commutating
thyristor pair was too small
2 The current crest curve breaks upwards
3 The maximum current value was higher than 250% of
rated device current
4 A paralleled SIMOREG DC Master has detected a
commutation failure or overcurrent
F031 Speed controller monitoring
(active in operating states of – –, I, II)
The monitor responds when the difference between the connectors selected in P590 and P591 (factory setting: Setpoint/actual
value difference of speed controller) exceeds the limit set in parameter P388 for longer than the time set in parameter P390.
Possible fault causes
♦ Open control loop
♦ Controller not optimized
♦ P590 or P591 is not correctly parameterized
