20AB042C3AYNANC0

The Allen-Bradley 20AB042C3AYNANC0 is a PowerFlex70 adjustable frequency AC drive. It features 240V AC power and 3PH, 42 Amps, 15 HP of output at normal duty and 10 HP of output at heavy-duty. It also has an IP66/NEMA Type 4X/12 (Indoor) enclosure. This unit features conformal coating, a full keypad, and an LCD, but it does not have a drive-mounted brake resistor. The 20AB042C3AYNANC0 is an enhanced control without a feedback AC drive. It has a ‘calculator-like’ number pad that facilitates data entry. It also has alternative function keys that enable shortcuts to common tasks. The control keys of this drive help in starting, stopping, speeding up, and giving directions to the users. This drive uses a variety of languages and this enables it to be used by different users who speak different languages. The languages supported by this drive include English, German, Spanish, Italian, Dutch, and Portuguese.

The 20AB042C3AYNANC0 features a PI control that eliminates the process loop controller. The flying start feature of this device enables uniform connection between rotating loads despite the command direction. The 20AB042C3AYNANC0 does this without needing a speed feedback device. It also has a fast-acting current limit and bus voltage regulation. These leads to unmatched acceleration and deceleration without the device tripping. The slip compensation of this unit provides minimum open-loop speed regulation across a wide speed range. The 20AB042C3AYNANC0 has a safe-off option, which prevents the drive from sending rotational energy to the motors by integrating a safety circuit with its power switching signals. It also has user sets that enable as many as three complete sets of parameter data to be used. This data can be loaded individually for varying batch processes.
