Vector control 4.15 Instructions for commissioning permanent-magnet synchronous motors

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.

Table 4-5	Motor data
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).
p0305		Rated motor current	-
p0307		Rated motor power	-
p0310		Rated motor frequency	-
p0311		Rated motor speed	-

If the torque constant kT is not stamped on the rating plate or specified in the data sheet, you can calculate this value from the rated motor data or from the stall current Io and stall torque Mo as follows:
