1.0 Overtemp. Inverter
"Inverter overtemperature"
(inverter heat sink)
Inverter temperature monitoring
measurements are outside of the permissible temperature
range, i.e. the error is triggered if the permissible lower limit
is undershot or the permissible upper temperature limit is
exceeded.
•
Depending on the cause: Reduce or increase the
ambient temperature
•
Check the FI fan / control cabinet ventilation
•
Check the FI for dirt
1.1 Overtemp. FI internal
"Internal FI overtemperature"
(interior of FI)

2.0 Overtemp. Motor PTC
"Overtemperature motor
thermistor "
Motor temperature sensor (PTC) has triggered
• Reduce motor load
• Increase motor speed
• Use external motor fan
2.1 Overtemp. Motor I²t
"Motor overtemperature I²t"
Only if I
2
t motor (P535) is
programmed.
I
2
t motor has triggered (calculated overtemperature of
motor)
• Reduce motor load
• Increase motor speed
2.2 Overtemp. Brake r.ext
"Overtemperature of external
brake resistor "
Overtemperature via digital
input (P420 […])={13}
Temperature monitor (e.g. brake resistor) has activated
• Digital input is Low
• Check connection, temperature sensor

3.0 I
2
t overcurrent limit
a.c. inverter: I
2
t limit has triggered, e.g. > 1.5 x I
n
for 60s
(also note P504)
• Continuous overload at inverter output
• Possible encoder fault (resolution, defect,
connection)
3.1 Chopper overtemperature I
2
t
Brake chopper: I
2
t limit has activated, 1.5 times values
reached for 60s (please also pay attention to P554, if
present, and P555, P556, P557)
• Avoid overcurrent in brake resistance
3.2 IGBT overcurrent
125% monitoring
De-rating (power reduction)
• 125% overcurrent for 50ms
• Brake chopper current too high
• for fan drives: enable flying start circuit (P520)
3.3 IGBT overcurrent fast
150% monitoring
De-rating (power reduction)
• 150% overcurrent
• Brake chopper current too high
