CP-Parameter for open-loop operation
CP27 Response Description
1 Quick stopping,
modulation off,
restart after reset
Status message „Warning! …“
Fast stop - switch off of 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.
2 Quick stopping,
holding torque,
restart after reset
Status message „Warning! …“
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.
3 modulation off,
automatic restart
Status message „Warning! …“
Immediate switch off of modulation; the drive re-
turns automatically to normal operation, as soon as
the fault no longer exists.
4 Quick stopping,
modulation off,
automatic restart
Status message „Warning! …“
Fast stop - switch off of modulation after reaching
0 Hz. the drive returns automatically to normal op-
eration, as soon as the fault no longer exists.
5 Quick stopping,
holding torque,
automatic restart
Status message „Warning! …“
Fast stop - holding torque on reaching 0 Hz. the
drive returns automatically to normal operation, as
soon as the fault no longer exists.
6 Warning signal by digital out-
put,
no message
No effect on the drive. Error is being ignored. Switch-
ing condition (CP32 and CP33) value „10“ is set.
CP28 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 specied value, if the motor has not been operated for
an appropriate time with underload.
CP29 motorprot. rated current
This parameter species the rated current (= 100% utilization) for the motor protective func-
tion. The motor protection-load is calculated as follows:
Inverter apparent current (CP04)
Motor protection load = –––––––––––––––––––––––––––––––
motorprot. rated current (CP29)
