Product Description:

The 8DI440.DA0220000-1 is a servo motor manufactured by B & R Automation for the 8DI ACOPOS Motors series. It is intended for direct integration with ACOPOS drives, where it supplies closed-loop torque and position control to conveyors, pick-and-place axes, and other industrial motion tasks. The device ships without a holding brake or oil seal and uses a smooth shaft end, features that suit it for clean, low-friction couplings inside protected machine enclosures. This layout also helps keep the output end simple for enclosed machine designs that do not require a sealing element.

The motor supports a rated speed of 2200 rpm, which is the continuous rotational velocity available when the drive runs the axis at nameplate conditions. Position feedback is absolute, with 524,288 (19-bit) counts delivered each revolution; this high resolution permits fine interpolation of incremental moves. Communication between encoder and drive follows the EnDat 2.2 protocol, so a single hybrid cable carries power and digital diagnostics. Rotor position is derived through inductive sensing, which tolerates temperature variation and magnetic fields better than optical systems. Functional safety is provided through hardwired safety technology, allowing the encoder’s safe single-turn values to be evaluated by an external logic circuit without relying on software redundancy. The feedback package supports accurate motion control while keeping signal transmission digital from the motor to the drive across the full operating cycle.

The remaining details describe shaft loading and motion tolerance. The assembly uses module size and length code 4, includes no special shaft option, and does not include a POWERLINK connector. A permissible axial force of 2300 N lets the shaft handle thrust from couplings or belt tensioners. Positional accuracy stays within ±65″ during operation. The housing withstands shock up to ≤2,000 m/s² and vibration levels of ≤200 m/s² / ≤600 m/s², which suits fast-moving gantries or end-of-arm tooling. The product is configuration version 1 for this release.
