106 Application macros
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 motor. To enable the macro, set the
value of parameter 9902 APPLIC MACRO to 3 (ALTERNATE).
For the parameter default values, see section Default values with different macros on
page 165. If you use other than the default connections presented below, see section
I/O terminals on page 49.
