[ 0 ]
By selecting the appropriate value and confirming it with the ENTER key, the selected parameter
range is entered in the factory setting. Once the setting has been made, the value of the
parameter returns automatically to 0.
0 = No change:
Does not change the parameterisation.
1 = Load factory settings:
The complete parameterisation of the FI reverts to the factory
setting. All originally parameterised data are lost.
2 = Factory settings without bus:
All parameters of the frequency inverter, with the
exception of the bus parameter, are reset to the factory setting.

Via this parameter both the
drive
[-01] and the
generator
[-02] switch-off value can be adjusted.
If 80% of the set value is reached, a warning status is set. At 100% switch-off is performed with
an error message.
Error 12.1 is given on exceeding the drive switch-off limit and 12.2on exceeding the generator
switch-off limit.

When calculating the motor temperature, the output current, time and the output frequency
(cooling) are taken into account. If the temperature limit value is reached then switch off occurs
and error message E002 (motor overheating) is output. Possible positive or negative effects of
ambient conditions cannot be taken into account here.

The I

t motor function can now be set in a differentiated manner. Up to four curves with three
different triggering times can be set. The trigger times are based on classes 5, 10 and 20 for
semiconductor switching devices.
Setting 5 corresponds to the previous setting “ON”.
All curves run from 0Hz to half of the nominal frequency (P201). From half of the nominal
frequency upwards, the full nominal current is available.
