Actual value memory

The assessment of the operating behavior and the maintenance 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 peri-
od. 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.
