p0304
Rated motor voltage
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.
p0305
Rated motor current
p0307
Rated motor power
p0310
Rated motor frequency
p0311
Rated motor speed
p0314
Motor pole pair number
If this value is not known, the value "0" can also be entered.
p0316
Motor torque constant
If this value is not known, the value "0" can also be entered.
If the torque constant k
T
is not stamped on the type plate or specified in the data sheet, you
can calculate this value from the rated motor data or from the stall current I
0
and stall torque
M
0
as follows:
or
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.
