8DI330.D90457100-1 by B & R Automation

The 8DI330.D90457100-1 is an integrated servo motor produced by B & R Automation within the 8DI ACOPOS Motors series. It combines drive electronics, feedback, and network connectivity in one enclosure. This layout supplies decentralized motion control for packaging machines, pick-and-place axes, and other automated stations where compact installation space is critical. The integrated format reduces the amount of separate axis hardware needed near the motor and keeps wiring concentrated at the machine. That arrangement is useful in tightly packed machine modules where cable paths and mounting space are limited.

This motor sustains a rated speed of 4500 rpm, giving rapid positioning cycles and a high rotational ceiling for short moves. Position feedback is delivered by a multi-turn functional safety encoder that resolves 4096 (12-bit) revolutions and transmits data through the EnDat 2.2 protocol. This arrangement provides absolute position information over multiple turns while maintaining a direct digital feedback link to the control electronics. Thrust loads can be transmitted through the smooth shaft, which supports up to 1400 N of permissible axial force, and the housing endures shocks up to <=2,000 m/s². The unit is version 1 with module size code 3 and length code 3. It is delivered without a holding brake, and the shaft carries an oil seal with no special shaft option applied.

An inductive operating principle inside the encoder head eliminates optical disks, helping the system achieve a directional precision of ±120" under dynamic loads. Machine safety circuits can be routed directly to the drive because the control section is designed for hardwired safety technology. The mechanical structure tolerates composite vibration levels of <=400 m/s² / <=600 m/s² along the principal axes, complementing the stated shock resistance during continuous motion. One additional POWERLINK port allows simple daisy-chain wiring, and on-board I/O includes two trigger inputs plus two 24 VDC transistor outputs for local sensors or actuators. These local connections let the motor exchange nearby signals without requiring separate interface hardware at the axis.
