6 Operating status messages
Cause
• Remedy
Temperature monitoring of the inverter
Warning, permissible temperature limit reached.
• Reduce ambient temperature
• Check device fan/cabinet ventilation
• Check the device for dirt
Warning from motor temperature sensor (triggering
threshold reached)
• Reduce motor load
• Increase motor speed
• Use external motor fan
Warning: I2t motor monitoring (1.3 times the rated current
reached for the time period specified in (P535))
• Reduce motor load
• Increase motor speed
Warning: Temperature monitor (e.g. braking resistor) has
activated
• Digital input is low
Warning: a.c. inverter: I
for 60 s (also note P504)
• Continuous overload at inverter output
2 2
t Warning: I t limit for the brake chopper has activated, 1.3
times values reached for 60 s (please also pay attention to
P554, if present, and P555, P556, P557)
• Avoid overcurrent in brake resistance
Warning: Torque current limit reached
• Check (P112)
Warning: Current limit reached
• Check (P536)
