When overtemperature is detected thedrive reacts as defined by parameter 31.01 Mot temp1 prot.Note: If one FEN-xx module is used, parameter setting mustbe either KTY 1st FEN or PTC 1st FEN. The FEN-xx modulecan be in either Slot 1 or Slot 2.Estimated The temperature is supervised based on the motor thermalprotection model, which uses the motor thermal time constant(parameter 31.14 Mot therm time) and the motor load curve(parameters 31.10…31.12). User tuning is typically neededonly if the ambient temperature differs from the normaloperating temperature specified for the motor.The motor temperature increases if it operates in the regionabove the motor load curve. The motor temperaturedecreases if it operates in the region below the motor loadcurve (if the motor is overheated).WARNING! The model does not protect the motor ifit does not cool properly due to dust and dirt.0KTY 1st FEN The temperature is supervised using a KTY84 sensorconnected to encoder interface module FEN-xx installed indrive Slot 1/2. If two encoder interface modules are used,encoder module connected to Slot 1 is used for thetemperature supervision.Note: This selection does not apply to FEN-01.2KTY 2nd FEN The temperature is supervised using a KTY84 sensorconnected to encoder interface module FEN-xx installed indrive Slot 1/2. If two encoder interface modules are used,encoder module connected to Slot 2 is used for thetemperature supervision.Note: This selection does not apply to FEN-01.3PTC JCU The temperature is supervised using a PTC sensorconnected to DI6.4PTC 1st FEN The temperature is supervised using 1...3 PTC sensorsconnected to encoder interface module FEN-xx installed indrive Slot 1/2. If two encoder interface modules are used,encoder module connected to Slot 1 is used for thetemperature supervision.5No. Name/Value Description FbEq
