4.2 Vector Control Drive Concept
A standard system concept is used with this drive; see
following hardware parts:
The drive can be controlled in two different operational modes:
In the Manual operational mode, the required speed is set by the Start/Stop switch and the Up/Down
push buttons.
In the PC master software operational mode, the required speed and Start/Stop switch are set by the
PC.
