KEBA D3-DA 3xx - axis controllers

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 250 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 30x.

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.
