Product Description:

The 8CVI045S1HCS0.00-1 is a compact inverter module developed by B & R Automation for the 8CVI ACOPOS Inverter Modules series. Serving as the power stage inside machine cabinets, the unit modulates a high-voltage DC link to supply three-phase AC motors and forms the interface between the drive controller and the motor winding. By converting DC energy into variable voltage and frequency, it supports precise speed and torque control in industrial automation lines.

For steady operation, the inverter delivers a motor shaft output of 1.5 kW while keeping the phase current at 4.5 Aeff. The internal DC link is stabilized at 750 VDC, giving the drive headroom for fast torque transients without reaching saturation. Pulse-width modulation is executed at a nominal carrier of 5 kHz, a rate that balances acoustic noise and switching losses. On the output side, the synthesized frequency can be raised up to 598 Hz, allowing the same hardware to run high-speed spindles or standard induction motors. These electrical limits indicate the continuous thermal load and help with the selection of matching motors and line filters.

Peripheral services are covered by a 24 V auxiliary rail that can source 8 A for actuators, sensors, and an encoder supply of 300 mA. During acceleration, the power stage tolerates a peak phase current of 13.5 Aeff, extending torque availability for brief load surges. The housing carries an IP65 rating, so the 137 mm-wide, 131 mm-deep, and 287.2 mm-high enclosure can be mounted outside a control cabinet without additional sealing, and the total mass is 4.8 kg. System communication uses POWERLINK at a line speed of 100 Mbit/s, enabling cycle-synchronous setpoint updates that match the drive's 12-bit ADC resolution. A 35 µF DC-bus capacitor supports these fast cycles by absorbing regenerated energy and smoothing link voltage.
