Yaskawa Electric Corporation CIMR-VA4K0004JSB VFD Drive

The Yaskawa CIMR-VA4K0004JSB is a hoist-rated AC variable frequency drive (VFD) from the V1000 family with custom hoist firmware that enables precise speed control, braking, and load management in cranes, hoists, elevators, and other lifting systems. It accepts 380–480 VAC three-phase input and delivers about 4.1 A output with a ~1.5 kW (2 HP) rating, supports V/f and sensorless vector control, and offers a 0–400 Hz frequency range for fine acceleration and deceleration. A hoist-focused firmware provides enhanced braking and load control; overload capability around 150% for 60 seconds. Mounting is panel-mounted with an IP20 enclosure and internal fan cooling, and the drive is positioned for legacy/service-repair and retrofit markets in hoists, cranes, lifting systems, and conveyors. Common replacements include CIMR-VC4A0004BAA, GA500 (hoist-capable configuration), and A1000 heavy-duty hoist upgrades.
