Sequence Control
The sequence control enables a cyclical program sequence with the fixed frequency setpoints
FF0 to FF7. To run the program you can also select from four different operating modes and
assign rotation direction (FWD/REV) and run time to the individual fixed frequencies. The
program sequence is programmed in binary code and is represented by a decimal number for
simple entry.
Fixed Frequency Setpoint Value, continued
The table below shows the parameters of the fixed frequencies (P10.1–P10.8) with the
associated run times (P10.11–P10.18) and the corresponding values in binary and decimal
format.
Depending on the selected rotating field direction (FWD/REV), the decimal value is multiplied
by 0 (= FWD) or 1 (= REV). The sum of all decimal values forms the program number for
parameter P10.10.
Determining the Program Number (P10.10)
The fixed frequencies (FF0–FF7) are only active if the run times (P10.11–P10.18) of the
associated parameters are set (>0s).
