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.
