1) Setting the electronic thermal protection characteristics selection and
motor electronic thermal protection level 1
The electronic thermal protection characteristics selection is used to enable or disable the motor
overload trip function ( ) and the overload stall function.
While the inverter overload trip (
) will be in constant detect operation, the motor overload trip ( )
can be selected using the parameter .
Explanation of terms
Overload stall: When the inverter detects an overload, this function automatically lowers the output
frequency before the motor overload trip is activated. The soft stall function
allows the drive to run with balanced load current frequency without a trip. This is an
optimum function for equipment such as fans, pumps and blowers with variable
torque characteristics that the load current decreases as the operating speed de-
creases.
Note: Do not use the overload stall function with loads having constant torque characteristics (such as
conveyor belts in which load current is fixed with no relation to speed).
[Using standard motors (other than motors intended for use with inverters)]
When a motor is used in the lower frequency range than the rated frequency, that will decrease the cooling
effects for the motor. This speeds up the start of overload detection operations when a standard motor is
used in order to prevent overheating.
