Nm
Specifies the duration for which the parameterised maximum
current may act. In the case of a servomotor, the current set-
point is automatically limited to the rated current at the end of
the period and the corresponding diagnostic message with the
parameterised behaviour is generated (I²t monitoring). If a
thermal model is used for I²t monitoring, as for a stepper motor
with rated current=maximum current, the time constant is used
as the filter time constant.
