Siemens 6RA70 Drive faults, F029 Motor overtemperature active in all operating states

Fault

No.

Description
Cause as a function of fault value	Further information (r047.002 to r047.016)
(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:

1Fault activation through temperature sensor at terminals 22 / 23

2Fault activation through temperature sensor at terminals 204 / 205

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:		r047 Index 002 to 016:
1	The blocking voltage time area for the commutating	i002	Delay angle (K0100) in case of error
	thyristor pair was too small	i003	Actual EMF (K0287) in case of error
2	The current crest curve breaks upwards	i004	Trigger circuitry diagnostics (K0989) in case of error
3	The maximum current value was higher than 250% of	i005	Actual field current (K0265) in case of error
	rated device current
		i006	Number of pulses (K0105) in case of error

4A 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
