Dual Setpoint with PID and Constant Speeds
This macro configures for applications with 2 constant speeds, active PID and PID
alternating between two setpoints using digital inputs. Set PID setpoints (internal to
the drive) using parameters 4011 (
SET
1) and 4111 (
SET
2). The digital input DI3
selects the setpoints.
