Alternate macro
This macro provides an I/O configuration adapted to a sequence of DI control
signals used when alternating the rotation direction of the drive. To enable the
macro, set the value of parameter
9902 to 3 (ALTERNATE).
For the parameter default values, see section Default values with different macros
on page 142 . If you use other than the default connections presented below, see
section I/O terminals on page 40 .
