Start-Up
Dual Setpoint with PID
This macro configures for dual setpoint PID applications, where activating digital
input 3 (DI3) changes the process PID controller’s setpoint to another value. When
using direct speed reference in AUTO mode or process PID, see "General
Considerations" on page 30. Set process PID setpoints (internal to the drive) using
parameters 4011 (
SET
1) and 4111 (
SET
2).
