Data set changeover
The inverter has two data sets, which can be switched with the control
inputs S1IND/S2IND. Each data set has a total of l8 parameters, which
can be set individually (see parameter description).
The truth table below refers to parameter 31-KSEL = 2 (data set selector)
Ramp changeover
As a consequence of the data set changeover option, the inverter has
2 ramp pairs available. The following sequence diagram illustrates the
function of the ramp changeover (with 31-KSEL = 2).
For more detailed information see parameter description.
