254 Operating Instructions ACU 12/16
226 Winding Temperature
Measured temperature of the motor winding according to Operation
Mode 465 for temperature adjustment
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-oriented control forming the
magnetic flux.
236 Torque-Forming
Voltage
Voltage component of the field-oriented control forming the torque.
238 Flux Value
Magnetic flux calculated according to the rated values and the
operating point of the motor.
239 Reactive Current
Reactive current calculated from the rated motor parameters, the
control variables and the current.
240 Actual Speed Measured or calculated speed of drive.
241 Actual Frequency Measured or calculated frequency of drive.
The actual values can be read out and monitored in the VAL menu branch of the
operating unit. Parameter
Control Level
28 in PARA menu branch defines the selection
of the actual value parameters to be selected.
20.3 Actual value memory
The assessment of the operating behavior and the service of the frequency inverter in the
application are facilitated by storing various actual values. The actual value memory guarantees
monitoring of the individual variables for a definable period. The parameters of the actual value
memory can be read out via a communication interface and displayed via the operating unit. In
addition, the operating unit provides monitoring of the peak and mean values in the VAL menu
branch.
