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.
Actual Values of the Machine
No. Description Function
210 Stator Frequency
The output voltage (motor voltage) of the frequency
inverter.
211 R.m.s current
Calculated effective output current (motor current) of
the frequency inverter.

221 Slip frequency
Difference from the synchronous frequency calculated
from the rated motor parameters, the control va-
riables and the current.
224 Torque
Torque at the current output frequency calculated
from the voltage, the current and the control va-
riables.
225 Rotor flux
Current magnetic flux relative to the rated motor
parameters.
226 Winding temperature
Measured temperature of the motor winding ac-
cording to O
peration mode
465 for temperature ad-
justment.
227 Act. rotor time constant
Time constant calculated for the operating point of
the machine from the rated motor parameters, the
rated and control variables.
235 Flux-forming voltage
Voltage component of the field-orientated control
forming the magnetic flux.
