Parameter
p0304 Rated motor voltage
p0305 Rated motor current
p0307 Rated motor power
p0310 Rated motor frequency
p0311 Rated motor speed
p0314 Motor pole pair number

The optional motor data can be entered if it is known. Otherwise, this data is estimated from
the type plate data or determined by means of motor identification or speed controller
optimization.

If this value is not known, the value "0" can also be
entered.
Entering the correct value, however, means that the
stator leakage inductance (p0356, p0357) can be
calculated more accurately.
If this value is not known, the value "0" can also be
entered.
