The Allen Bradley 20BC260A0ANNACC0 operates as an AC variable frequency drive (VFD) tailored for advanced motor control tasks. It is engineered to accept a mains supply of 400V AC, 3-phase, at a frequency of 50 Hz. This drive is capable of supporting a normal duty power of 132 kW, corresponding to 177 kVA, and has a maximum heavy-duty power rating of 110 kW. Notably, it can deliver a continuous output current of 260 Amps under the specified conditions, while its input current rating stands at 255 Amps.
Protection from environmental factors is afforded by its enclosure, which is rated at IP20 and complies with NEMA Type 1 standards. This rating allows placement in typical indoor situations without exposure to severe dust or moisture. The drive’s operational features include a control method based on sine-coded PWM, with carrier operations adjustable between 2 to 10 kHz—this enables fine control over motor performance.
Users can select between two motor control modes: sensorless vector control for enhanced performance or a custom V/Hz control for simpler applications. In addition to its robust control methods, the drive supports a ControlNet coaxial DPI communication module, aiding in integration with other control systems. Input and output capabilities are adequate for most setups featuring 6 digital inputs and 3 outputs, alongside 2 analog inputs and 2 outputs. It is worth noting that this model does not include a brake IGBT, which may be relevant in applications requiring dynamic braking.
