Warning and fault
Class 20 / uint16Defines the motor overload class to be used. The class
of protection is specified by the user as the time for
tripping at 7.2 times (IEC 60947-4-1) or 6 times (NEMA
ICS) the tripping level current.

0.0 % / real32Shows the calculated temperature of the motor cable.
See section Thermal protection of motor
cable (page 133).
102% = overtemperature warning (A480 Motor cable
overload)
106% = overtemperature fault (4000 Motor cable
overload)
This parameter is read-only.
Cable temperature35.60
1 = 1 % / 10 = 1 %Calculated temperature of motor cable.0.0 ... 200.0 %
10000.00 A / real32Specifies the continuous current of the motor cable
for the thermal protection function in the control
program.
WARNING!
The value entered in this parameter must be
limited according to all factors affecting the
loadability of the cable, such as ambient
temperature, cabling arrangement, and
shrouding. Refer to the technical data from the
cable manufacturer.
