6 Operating status messages
Cause
• Remedy
Inverter temperature monitoring
Warning: permissible temperature limit reached.
Reduce ambient temperature
•
• Check the FI fan / control cabinet ventilation
• Check the FI 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. brake resistor) has
activated
• Digital input is Low
2
Warning: Inverter: I t limit has triggered, e.g. > 1.3 x I
60s (please also note P504)
• Continuous overload at FI output
2
Warning: I t limit for the brake chopper has triggered, 1.3x
value attained for 60s (also note P554, if present, as well as
P555, P556, P557)
• Avoid overload of brake resistance
Warning: Torque current limit reached
