− Frequency: Refers to Maximum Frequency 419. Maximum Frequency 419 refers to
100.00 %
− Voltage: Refers to 400 V
eff
(bzw. 400 √2 V
peak
). The value refers to 100.00 %.
Mathematical functions use percentage values as input and output values.
Internal conversions
Internal values of the frequency inverter are processed as percentage value. Frequencies, Cur-
rents and voltage are converted.

The instructions are processed cyclically. In the first step, the output buffer is written to the
global variables, then the input buffer is written to the sources.
Then the instructions are processed, starting with Index 1.
