P8-17
Running direction
of programs
0-255 BIT0-7 indicates directions
for 0-7 (0:FWD 1:REV)
Default : 0
The P8-17 parameter determines the direction that will be followed for the individual phases in the
simple PLC program.

Each bit in the byte corresponds to the corresponding phase in the simple PLC program as shown in
the table above.
A value 0 in the bit corresponds to a FWD direction rotation while writing a value 1 to the bit will
cause REV direction rotation.
In the above example, we have phases 0 (principal frequency), 2, 3, and 5 running in the forward
direction while
phases 1, 4, 6, and 7 will run in the reverse direction. The parameter value comes out to be
