Motor thermistor over temp

What does 11 mean?

The motor thermistor indicates an over-temperature condition, or the thermistor itself may be disconnected or improperly wired. This suggests the motor is overheating, which can lead to severe damage if left unaddressed. Select whether the frequency converter issues a warning or an alarm in 1-90 Motor Thermal Protection.
