P 4.6.3 Warning Current High
Enter the I-high value. When the motor current exceeds this limit, a bit in the drives status word is set. This value can also be
programmed to produce a signal on the digital output or the relay output.

P 4.6.7 Motor Thermal Protection
Motor thermal protection can be implemented via a PTC sensor in the motor windings connected to 1 of the analog or digital inputs (P
4.6.8 Thermistor Source). Or via calculation (ETR = Electronic Thermal Relay) of the thermal load, based on the actual load and time. The
calculated thermal load is compared with the rated motor current I

Selection description
Continuously overloaded motor, when no warning or trip of the
frequency converter is required.
Activates a warning when the connected thermistor in the motor
reacts to a motor overtemperature.
Stops (trips) the frequency converter when the connected
thermistor in the motor reacts to a motor overtemperature. The
thermistor cut out value must be >3 kΩ. Integrate a thermistor
(PTC sensor) in the motor for winding protection.
