Operating Principle
The simplified diagram of the AMD5x control is shown below. The 3 phase AC supply voltage is converted to DC,
which is then distributed via a bus to each Drive. The number of drives is chosen by the customer. Each drive
converts the DC into the required variable frequency AC voltage signal to drive each motor.
