10 Structure of the drive axis
The drive axis consists of a mechanical and an electrical part.
• The mechanical system comprises the mechanics of the application, the gearbox, possibly an
additional drive element, the motor, the feedback system, and a possibly available mechanical
brake.
• The electrical system (power transmission) includes the mains supply, mains chokes and filters,
the inverter with an electrical brake unit, possibly motor chokes, and system cables.
• Mains chokes, filters, motor chokes and cables are not an integral part of the DSD.
• The motor and feedback system provide the transition between the mechanical and electrical
system of the drive axis.
• Apart from these two basic structures of power transmission you also have to consider the con-
trol system which can be divided into the areas functions, safety concept, and communication
(bus system).
• In the DSD the control system is only taken into consideration to a limited extent.
