Application macros
Dual Setpoint with PID macro
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

. Set process PID setpoints (internal to the drive) using
parameters 4011 (
SET
1) and 4111 (
SET
2).
