Error group 2 Undervoltage in intermediate circuit
No. Code Message Reaction
2-0 3220h Undervoltage in intermediate circuit configurable
Cause Intermediate circuit voltage falls below the parameterised
threshold (è Additional information).
Error priority set too high?
Action Quick discharge due to switched-off mains supply.
Check power supply.
Couple intermediate circuits if technically permissible.
Check intermediate circuit voltage (measure).
Check undervoltage monitor (threshold value).
Additional
info
Additional information in PNU 203/213:
Upper 16 bits: Status number of internal state machine
Lower 16 bits: Intermediate circuit voltage (internal scaling approx.
17.1 digit/V).
Error group 3 Motor overtemperature
No. Code Message Reaction
3-0 4310h Analogue motor overtemperature QStop
Cause Motor overloaded, temperature too high.
– Motor too hot?
– Incorrect sensor?
– Sensor defective?
– Cable fracture?
Action Check parameters (current regulator, current limits).
Check the parametrisation of the sensor or the sensor charac
teristics.
If the error persists when the sensor is bypassed: Device defective.
3-1 4310h Digital motor overtemperature configurable
Cause – Motor overloaded, temperature too high.
– Suitable sensor or sensor characteristics parametrised?
– Sensor defective?
Action Check parameters (current regulator, current limits).
Check the parametrisation of the sensor or the sensor charac
teristics.
If the error persists when the sensor is bypassed: Device defective.
3-2 4310h Analogue motor overtemperature: Broken wire configurable
Cause The measured resistance value is above the threshold for wire
break detection.
Action Check the connecting cables of the temperature sensor for wire
breaks.
Check the parametrisation (threshold value) for wire break
detection.
