Product Overview
The B&R 8V1090.00-2 is a modular ACOPOS servo drive rated at
4 kW and 8.8 A. It supports three-phase 400 to 480 VAC mains input and
incorporates a line filter, braking resistor and electronic restart inhibit.
Four plug-in module slots allow the drive to be configured with the communication,
encoder and additional interface modules required by the machine. Exact replacement
therefore requires verification of both the base drive and every installed 8AC module.

Compatible System and Applications
The drive is used for servo-axis control in packaging, printing, plastics processing,
textile, material-handling, metalworking and automated production machinery. Final motor
compatibility depends on the motor rating, encoder interface, motor cable, feedback cable
and drive configuration.
Maintenance and Replacement Notes
Before ordering, verify the complete drive model, mains voltage, current rating, motor
model, encoder type, brake requirement, installed plug-in modules, POWERLINK or other
network interface, firmware, controller project and parameter backup.
The holding-brake circuit and electronic restart inhibit must not be treated as a complete
personnel-safety function without validation of the entire machine safety architecture.
Related Models
Related ACOPOS drive ratings include 8V1045.00-2, 8V1022.00-2 and 8V1180.00-2. Different
8V current ratings are not direct replacements unless motor sizing, mains supply and drive
parameters are reviewed.
Inquiry and Supply Notes
Provide the complete drive nameplate, installed 8AC module list, motor nameplate,
communication network, firmware version, controller project and cable references for an
accurate compatibility assessment.
