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.
