2.3.1 Control Structure Open Loop
In the configuration shown in Illustration 2.13 , parameter 1-00 Configuration Mode is set to [0] Open loop . The resulting
reference from the reference handling system or the local reference is received and fed through the ramp limitation and
speed limitation. After that, it is sent to the motor control. The output from the motor control is then limited by the
maximum frequency limit.
