Yaskawa Electric Corporation CIMR-AU4A0031FAA Variable Frequency Drive

The Yaskawa CIMR-AU4A0031FAA is a 20 HP A1000 Series variable frequency drive that precisely speeds and torque-controls industrial motors in demanding automation systems. It accepts 3-phase 380–480 VAC input and delivers about 31 A output (with an input current around 24 A), enabling efficient motor control in conveyors, pumps, compressors, and other heavy-duty equipment. The drive supports vector control and V/f control, with a frequency output up to 400 Hz, and is housed in a NEMA 1 / IP20 panel-mounted enclosure for indoor industrial installations. Key features include auto-tuning, network communication capability, and expandable I/O, making it suitable for retrofits and upgrades in material handling, HVAC, water and wastewater treatment, and manufacturing lines where controlled acceleration and torque stability drive energy efficiency. Common replacements include CIMR-AC4A0031FAA, CIMR-VU4A0031FAA, and CIMR-VC4A0031FAA.
