Object target velocity is the speed reference value for the frequency inverter. Target
velocity is interpreted as a speed with the unit RPM. The inverter's internal reference
frequency is calculated from the target velocity in RPM taking into account parameter
No. of Pole Pairs
373.
The parameter
No. of Pole Pairs
373 has four different data sets. In motion control
applications (configuration = x40) only the data set 1 is used.
Non motion control applications (configuration
≠
x40) sometimes have more than one
motor connected to the inverter (only one at a time, switched over by contactor).
These motors may have a different no. of pole pairs. The entry in
No. of Pole Pairs
373 is then different in the four data sets. After change-over of the motor, the object
target velocity must be written at least once in order to recalculate the internal refer-
ence frequency of the inverter using the correct no. of pole pairs.

In Non motion Control configurations (conf. ≠ x40) the target velocity reference value is
product-internally connected to the Reference line value. This reference value is
combined with the internal reference frequency value from the frequency reference
value channel in the input of the ramp function (see chapter 14.3.3 “Reference value /
actual value”).
