Operating Instructions ACU
The calculated energy from the motor in generator operation.
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.
Parameter Reset Memory 237 which is to be selected in the PARA menu branch of the operating
unit enables purposeful resetting of the individual mean and peak values. The peak value and the
mean value with the values stored in the period are overwritten with the parameter value zero.
Values of actual value memory remain unchanged.

20.4 Actual values of the system
The calculation of the actual figures of the system is based on the parameterized system data.
Specific to the application, the parameters are calculated from the factors, electrical variables and
the controls. The correct display of the actual figures is a function of the data of the system to be
parameterized.
20.4.1 Actual value system
The drive can be monitored via actual value Actual Value System 242.
The Actual Frequency 241 to be monitored is multiplied by the Factor Actual Value System 389
and can be read out via parameter Actual Value System 242, i.e. Actual Frequency 241 x Factor
Actual Value System 389 = Actual Value System 242.
Calculated frequency of drive.
