PTC Evaluation
Supplementary parameter for PTC in P0385
Fault

The following options can be selected when the selected PTC
switching value (P389) is reached:
0 = Alarm (alarm, motor temperature)
1 = Fault (fault, motor temperature)
0 / 1

PTC Switch value
Supplementary parameter for PTC in P0385
4000
Ω
1
Enter the resistance switching threshold to initiate the re-
sponse set using P388 (PTC evaluation).
1000 .. 4500 W
0565
Sel. overload prot.
no reation
2
The overload protection function is implemented corre-
sponding to the SIEMENS overload relay 3UB1, setting class
10.
The following options can be selected for the response of the
IxT overload protective function:
0 = no reaction
1 = warning
2 = fault
0 ... 2

Curr.overload prot.
Refer to Fig. 5-4:

Current threshold for the Ixt overload protection function.
When the Ixt threshold is reached, the response, set with
P565 is initiated.
Emulation of the thermal overload trip
When the motor rating plate data is changed, P0566 is set to
the rated motor current.
