Open-loop
Motor speed is determined by applying a speed reference or by setting desired speed when in hand
mode.
Open-loop is also used if the adjustable frequency drive is part of a closed-loop control system based
on an external PID controller providing a speed reference signal as output.
[3]
Closed-loop
Motor speed will be determined by a reference from the built-in PID controller varying the motor
speed as part of a closed-loop control process (e.g., constant pressure or flow). The PID controller
must be configured in par. 20-** or via the function set-ups accessed by pressing the [Quick Menu]
button.
NOTE!
This parameter cannot be changed when the motor is running.
NOTE!
When set for closed-loop, the commands reversing and start reversing will not reverse the direction of the motor.
