Product Description:

B & R Automation manufactures the 8V1640.13-2, a servo drive belonging to the 8V1 ACOPOS Servo Drives series. The device converts energy from the shared DC link into controlled three-phase output for a single motor, allowing rapid torque and velocity regulation in packaging machines, pick-and-place gantries, and other coordinated multi-axis systems. By monitoring feedback and modulating its IGBT bridge, the drive maintains command fidelity while protecting the motor from overload.

The power section is sized for a continuous output of 64 Aeff, which is the steady-state line current the unit can deliver without thermal derating. Rated apparent power reaches 32 kW, matching medium-frame motors typically used on conveyor or spindle axes. A DC-bus capacitor bank of 3300 µF smooths the intermediate-circuit voltage and stores regenerated energy during braking events. The gate pattern is refreshed at a nominal switching frequency of 10 kHz, so output harmonics stay above the mechanical bandwidth of most loads. During startup, the rectifier draws 26 A of inrush at 400 VAC, and the installation must therefore include appropriately delayed fusing. Aggregate installed load is 54 kVA, while standby losses remain limited to 32 W when the enable signal is low.

For dynamic peaks, the current reserve climbs to 200 Aeff, and the output waveform may rise to 598 Hz to support high-speed servo motors. Motor cables can be routed up to 25 m without additional filters, which is sufficient for most cabinet-mounted layouts. The housing carries a protection rating of IP20, so it must be mounted inside a closed electrical enclosure that provides airflow around its 276 mm width, 295 mm depth, and 460 mm height. Total mass is 24.1 kg, and four plug-in module slots provide space for encoder, fieldbus, or safe-motion options.
