Description
Motor thermal time constant.
Selects the action taken when motor overload is
detected.
See section Motor overload protection (page
No action taken.
Drive generates warning
the motor is overloaded to the warning level, that is,

is overloaded to the fault level, that is, parameter
Motor overload level reaches value 100.0%.
Defines 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.
See section Motor overload protection (page

This parameter is read-only.
Calculated temperature of motor cable.
Specifies 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.
