Product Overview
The B&R 8V1640.001-2 is an ACOPOS 1640 servo drive designed for industrial motion-control applications. It accepts a three-phase 400–480 VAC supply and supports 50/60 Hz operation. The unit has a maximum installed load of 54 kVA and includes an integrated line filter, DC bus power supply, braking resistor, and electronic safe restart inhibit.
This version uses partially coated printed circuit boards, identified by B&R ID code 0xA09C. The modular design provides four slots for plug-in modules, allowing the drive configuration to be adapted to the requirements of the control system.

Application
The ACOPOS 1640 is intended for machine motion-control systems where a high-power servo drive is required. Typical applications can include:
- Automated production machinery
- Packaging and material-handling equipment
- Industrial positioning systems
- Machine tools
- Multi-axis motion-control systems
- High-power servo motor applications
The actual motor, feedback interface, fieldbus configuration, and plug-in modules should be matched to the existing B&R system configuration before replacement.
Installation & Configuration
Before installation, verify the drive model, nameplate data, mains voltage, motor rating, installed option modules, and existing B&R configuration.
The unit requires a suitable three-phase 400–480 VAC supply. Proper grounding and cabinet ventilation are important because the manufacturer specifies approximately 1600 W of power dissipation at nominal device power without the braking resistor.
For replacement work, compare the existing plug-in modules and interfaces with the replacement unit. B&R Automation Studio hardware configuration should also be checked before commissioning.
Do not connect or disconnect power wiring while the drive is energized. Allow sufficient time for the DC bus to discharge and verify the DC bus voltage with appropriate test equipment before servicing.
Maintenance Recommendations
Keep the drive installed in a clean, dry control cabinet and maintain adequate airflow around the unit.
During inspection, check:
- Cooling paths and ventilation
- Power and motor terminals
- Ground connections
- Plug-in modules and connectors
- Signs of overheating or discoloration
- DC bus and braking-resistor circuitry
- Error and diagnostic information
If the drive is removed from service for an extended period, protect it from moisture, dust, and electrostatic discharge.
Replacement Notes
The suffix “.001-2” is significant. It identifies the version with partially coated printed circuit boards, so it should not automatically be treated as identical to every 8V1640 variant. B&R lists the standard 8V1640.00-2 and the 8V1640.001-2 as separate product variants.
When replacing an existing unit, compare the complete part number rather than matching only “8V1640”.
