Alternate macro

This macro provides an I/O configuration adopted to a sequence of DI control
signals used when alternating the rotation direction of the motor. To enable, set the
value of parameter 9902 to 3 (
Connection example:
1...10 kohm
• Analog reference (AI1)
• Start, stop and direction (DI1,2)
• Constant speed selection (DI3,4)
• Ramp pair 1/2 selection (DI5)
• Run enable (DI6)
