Function:
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 frequency converter is part of a closed loop control system based on
an external PID controller providing a speed reference signal as output.
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 Setups accessed by pressing the [Quick Menus]
button.
