8DI330.D90457700-1 by B & R Automation

The 8DI330.D90457700-1 belongs to the 8DI ACOPOS Motors series produced by B & R Automation. It is an inductive AC motor module intended for precise axis control on the ACOPOS drive platform, where it delivers closed-loop positioning and speed regulation for conveyors, indexers, and handling units in automated lines.

The motor reaches a rated speed of 4500 rpm, giving adequate headroom for rapid cycle machines. Its absolute encoder distinguishes 4096 (12-bit) revolutions, enabling fine multi-turn feedback without homing. Position data is carried over EnDat 2.2, so the drive receives digital position and diagnostic information on a single pair. Motion repeatability is held within ±120", supporting accurate pick-and-place or metering tasks. A permissible axial load of 1400 N lets the keyed shaft accept moderate belt tension or thrust couplings. The module includes a holding brake for power-off clamping, carries module length code 3 and size code 3 for cabinet planning, and uses an oil seal to contain lubricant. Two 24 V DC outputs and two trigger inputs are provided for local sensor or actuator wiring, while the inductive operating principle removes magnetic hysteresis. Multi-turn functional safety is integrated at the encoder, and no special shaft option simplifies spare-part stock.

For network topology, there is one additional POWERLINK connection that supports line or ring layouts without external switches. The unit meets <=2,000 m/s² shock resistance and a vibration endurance of <=400 m/s² / <=600 m/s², matching typical plant floor dynamics. Its hardwired safety technology channel allows emergency-stop chains to bypass fieldbus latency. A keyed shaft end couples directly to standard hub components, and configuration version 1 ensures parameter sets stay consistent across replacements.
