CP.28 Motor protection / mode
The cooling mode of the motor is adjusted with these programmable parameters.
Value Condition
0 Motor with separate cooling
1 Motor with self-cooling
For self-ventilated motors the tripping times decrease with the frequency of the motor. The
motor protective function acts integrating, i.e. times with overload on the motor are added,
times with underload are substracted. After triggering the motor protective function, the new
tripping time is reduced to 1/4 of the specified value, if the motor has not been operated for
an appropriate time with underload.
CP.29 Motor protection / rated current
This parameter specifies the rated current (= 100% utilization) for the motor protective
function. The motor protection-load is calculated as follows:
Motor protection load
Description
Fast stop - switch off of the modulation after reaching
0 Hz. Correct the error for the restart and activate
reset. The drive remains in condition fast stop until a
reset signal is recognized.
Fast stop - holding torque on reaching 0 Hz. Correct
the error for the restart and activate reset. The drive
remains in condition fast stop until a reset signal is
recognized.
Immediate switch off of the modulation; the drive
returns automatically to normal operation, as soon
as the fault no longer exists.
Fast stop - switch off of the modulation after reaching
0 Hz. the drive returns automatically to normal opera-
tion, as soon as the fault no longer exists.
Fast stop - holding torque on reaching 0 Hz. the drive
returns automatically to normal operation, as soon as
the fault no longer exists.
No effect to the drive. Error is being ignored. Switching
conditions (CP.32 and CP.33) value „10" are set.
