Indramat DDC

Indramat DDC

The DDC 1.2, featuring an IP65 protection rating, can be mounted directly at the feeder station, functioning well even in challenging conditions and reducing the risk of faults associated with long cabling. Its construction includes a DC bus converter, a bleeder resistor for energy dissipation during braking, a main contactor to cut power, and a section for control voltage regulation. It accommodates various application-specific plug-in cards in slots U1 to U5.

Indramat supplies the DDC as a fully assembled and configured unit, comprising a basic unit, a command interface card, a software module, and, if required, additional auxiliary plug-in modules. It also includes a configuration rating plate for specifications. Each of these components is detailed in specific sections of the documentation.

Interface Options

The DDC controllers offer a selection of command interface modules suitable for various functions. These modules can either connect to the Numerical Control (NC) unit or provide positioning control with interfaces for manual operation or machine control. The available interface cards include:

- SERCOS interfaces, coming in types DSS 1.1 and DSS 1.3, which enable digital communication for servo drives.
- An ANALOG interface with an incremental encoder emulator, designated as type DAE 1.1, to replicate encoder signals.

OG interface with an absolute encoder emulator, labeled as type DAA 1.1, which simulates absolute encoder signals.
- A Positioning module, type DLC 1.1, designed for precise position control tasks.
