Product Description:

The DDS02.1-W100-DS45-01-FW is a digital AC servo drive controller in the DDS Drive Controllers series. It mounts on a backplane beside a regulated power supply and shares the common DC bus, creating a modular drive stack for multi-axis equipment. In machining centers, packaging machines, and assembly lines, the unit converts motion commands from the machine control into precise three-phase output so connected motors can maintain commanded position, speed, and torque during changing loads. Because it operates as part of a modular stack rather than as a standalone power section, it fits cabinets where several servo axes must be arranged closely together. Its slim housing and plug-in connections also help reduce cabinet space while keeping the overall layout easy to route.

At the power stage, the controller can deliver a continuous output of 100 A. Real-time command and diagnostic data move over the SERCOS interface, which uses a fiber-optic ring to reduce electrical noise and support deterministic update cycles. Rotor position is returned through digital servo feedback, allowing high-resolution commutation without analog converters. This feedback path lets the controller close motion loops directly at the drive, which supports accurate response during rapid acceleration and load reversals. Thermal energy is removed by internal cabinet air cooling, so enclosure airflow must keep the electronics within the permitted temperature range. The product belongs to Line 02 of the platform.

The drive uses Function ID 01 for its functional feature set and Version 1 for its build revision. These identifiers keep operating behavior consistent across matching axes in the same machine, so the controller responds with the same feature set and revision level wherever the same unit is installed. In multi-axis equipment, the modular arrangement keeps the supply stage separate from the axis controller while preserving a compact cabinet layout. That approach suits machines that need several coordinated servo channels without giving each axis a standalone power supply.
