Temperature protection can be implemented using a temperature sensor (KTY/PTC). In
order to achieve a high torque accuracy, we recommend that a KTY temperature sensor is
used.

Parameter Description Remark
p0304 Rated motor voltage If this value is not known, a "0" can also be
entered. Using this value, the stator leakage
inductance can be more precisely calculated
(p0356, p0357).
