Product Description:

The 8CVI045E1HCS0.00-1 is an inverter module produced by B&R Automation and supplied within the 8CVI ACOPOS Inverter Modules series. Installed between the DC bus and an AC motor, it converts shared DC-link energy into regulated three-phase output for speed and torque control in industrial automation cells. Cold-plate construction lets the unit mount to a liquid-cooled backplane, so cabinet heat is transferred to an external heat exchanger instead of being released into the drive stack. This arrangement supports dense machine layouts where thermal management must remain predictable during continuous operation.

This model can deliver up to 1.5 kW of continuous mechanical power to the connected motor while supplying a continuous output current of 4.5 Aeff. A stabilized DC link of 750 VDC feeds the IGBT output stage, and the integrated capacitor bank provides 35 µF to absorb load transients and smooth ripple on the bus. Pulse-width modulation operates at a nominal switching frequency of 5 kHz, which affects current control behavior and the audible response of the motor. These electrical values suit servo and spindle duties that require controlled acceleration, repeatable speed regulation, and stable torque delivery over long production cycles.

For intermittent demand, the drive can supply up to 13.5 Aeff, providing additional torque during short acceleration periods. Vector control supports carrier behavior that permits output frequencies up to 598 Hz, allowing high-speed motors to run over a broad operating range. The housing has an IP65 rating, which helps protect the electronics from dust and low-pressure water jets when the unit is mounted on the machine. Real-time coordination with adjacent modules takes place over POWERLINK 100BASE-T, carrying cyclic commands and diagnostic data through a single Ethernet connection. The module also supports a holding-brake supply of 1.1 A, encoder cable lengths up to 10 m, and overall dimensions of 287.2 mm × 137 mm × 131 mm with a mass of 4.8 kg.
