8DI330.D90450001-1 by B & R Automation

The 8DI330.D90450001-1 is a motor module produced by B & R Automation for the 8DI ACOPOS Motors series. It serves as a drive element that converts electrical command signals into rotary motion for positioning tasks in automated machinery. Within an ACOPOS multi-axis system, the module contributes precise feedback and torque generation to support coordinated motion.

The module reaches a rated nominal speed of 4500 rpm, allowing fast cycle times when that rotational velocity matches the application load. Position data are resolved into 4096 (12-bit) distinct revolutions, and each revolution is tracked by an EnDat 2.2 interface. This serial encoder delivers both position and diagnostic data through a bidirectional channel. The encoder uses a multi-turn functional safety design, and its sensing elements rely on an inductive operating principle that is immune to magnetic interference. Angular precision is specified at ±120", so the controller can command fine incremental moves without exceeding that error band. There is no additional POWERLINK connection on this product because feedback and power are combined in the standard hybrid connector.

Mechanically, the module tolerates an axial load of 1400 N on the shaft and withstands shocks up to <=2,000 m/s² during handling or abrupt stops. Continuous service vibration is limited to <=400 m/s² / <=600 m/s² depending on orientation, and hard-wired functional inputs provide hardwired safety technology without reliance on software channels. The smooth shaft end and a special-purpose 14h6 interface with 30 mm length simplify coupling to keyed or clamped hubs. This model is supplied without a holding brake, and no oil seal is installed, so external sealing must be provided if exposure to lubricants is expected. Module size code 3 and length code 3 define its frame envelope, while configuration version 1 denotes the first released hardware revision.
