Parameter Reference
AC30 series Variable Speed Drive
Motor Load
Parameters::Motor Control::Motor Load
Motor Protection, function of the motor type.
The
Motor Load parameters determines the allowed level of motor overload. This can be especially useful when operating with motors smaller than
the drive rating.
For an IM, an IxT protection is used and provides a current reduction if the max overload level is reached.
The max overload level is calculated based on a 150% for 60s.
For a PMAC motor, the motor load is calculated using the rated motor current and the thermal time constant (2 parameters of the PMAC motor
module). The Thermal time constant is used as the constant time of a simple 1
st
order low pass filter.
% Are all related to rated motor current.
