KEBA KeDrive D3-DA axis controller

Comprehensive performance scaling

The drive system KeDrive D3 offers axis controllers as single-axis, double-axis and triple-axis controllers in a power range up to

300 A for optimal system design.

Cost-effective drive systems for 4 axes (3 + 1), 5 axes (3 + 2), 6 axes (3 + 3) or more can therefore be combined without problems

and that not only for a specific sector, as the control technology meets the highest requirements even applications in the machine

tool industry are possible. Due to the innovative usage of technology, the control performance also remains identical independent of

the number of drive controller axes. Thanks to the development of a special drive ASIC, consistent performance from single-axis to

triple-axis controllers is realised.

There are also no restrictions on the usage of different encoder technologies, as proven interfaces such as resolver, sine/cosine,

HIPERFACE® or EnDAT are available along with the latest one-cable solutions to the servomotor.

Central supply

D3-DA 3xx axis controllers are supplied with power and auxiliary power via a central supply unit D3-DP 300.

The number of axis controllers that can be arranged beside a supply unit is dependent on the power (power supply and auxiliary

power supply) required for the application and must be taken into account during the project planning of the multi-axis system.

A maximum of 8 axis controllers (corresponding to a maximum of 24 axes) can be operated on a supply unit.

With the aid of the expansion module, a second row can be established and in this way the number of axis controllers expanded.

Safety technology

The axis controller provides scalable integrated safety technology. In the standard model the functions STO (Safe Torque Off)

and SBC (Safe Brake Control) are available. The expanded, optional "functional safety" forms, together with the central safety

control FSM, a system for axis monitoring connected via EtherCAT. This can include safe and non-safe encoders and encoder

combinations (HIPERFACE DSL®, SinCos, resolver, TTL and HTL) that are evaluated directly on the axis controller.

Field bus

The D3-DA 3xx axis controllers are designed for operation on the EtherCAT CoE field bus system. Bus cycle times of a minimum of

125 µs can be configured. Operation on alternative field bus systems such as Powerlink or PROFINet is also possible.

In operation, service and diagnostics access is by tunnelling via the central controller (EtherCAT EoE). For this purpose the controller

must support the routing function for TCP/IP communication via EoE (Ethernet-over-EtherCAT). Digital inputs are available for axis

related functions, such as limit switch or reference mark evaluation.
