Application macros
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 (
ALTERNATE
).
Connection example:
Input signals Output signals Jumper setting
• Analog reference (AI1)
• Start, stop and direction (DI1,2)
• Constant speed selection (DI3,4)
• Ramp pair 1/2 selection (DI5)
• Run enable (DI6) • Analog output AO1: Speed
• Analog output AO2: Current
• Relay output 1: Ready
• Relay output 2: Running
• Relay output 3: Fault (-1)

Start fwd: If DI1 state is the same as DI2, the drive stops
Start reverse
Ramp pair selection: Activation selects 2nd acc/dec ramp pair
Run enable: Deactivation always stops the drive
