18.2 Actual Values of the Machine
The frequency inverter controls the behavior of the machine in the various operating
points. As a function of the configuration selected and the expansion cards installed,
control variables and further actual value parameters of the machine can be dis-
played.

according to O
peration Mode 465 for tempera-
ture adjustment.
227 Act. Rotor Time Constant
Time constant calculated for the operating point
of the machine from the rated motor parame-
ters, the rated and control variables.
235 Flux-Forming Voltage
Voltage component of the field-orientated control
forming the magnetic flux.
236 Torque-Forming Voltage

240 Actual Speed Measured and/or calculated speed of drive.
241 Actual Frequency Measured and/or calculated frequency of drive.
Note: The actual values can be read out and monitored in the VAL menu
branch of the operating unit. The parameter
Control Level 28 in the
PARA menu branch defines the selection of the actual value parameters
to be selected.
