Application Macro: Alternate

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

14 DI2 Start reverse
15 DI3 Constant speed selection
16 DI4 Constant speed selection
17 DI5 Ramp pair selection: Activation selects 2nd acc/dec ramp pair.
18 DI6 Run enable: Deactivation always stops the drive
