Yaskawa CIMR-VUBA0018BAA

The CIMR-VUBA0018BAA is a single-phase, 240V AC variable frequency drive rated at 3.7 kW, belonging to Yaskawa's V1000 compact drive series. Designed for space-constrained installations where panel real estate is at a premium, the unit delivers adjustable-frequency motor control across a broad torque range without requiring a full-size enclosure. The V1000 series occupies Yaskawa's entry-to-mid tier, positioned between the J1000 basic drives and the higher-performance A1000 family, making the Yaskawa CIMR-VUBA0018BAA a practical choice where advanced vector control is needed without the added cost of full-feature high-end drives. At its core, the unit accepts single-phase 240V input and conditions it for three-phase output to the connected motor load, enabling the use of standard three-phase motors on single-phase power supplies — a configuration common in light industrial and commercial settings. The drive supports both V/f control and closed-loop vector control modes, giving engineers flexibility in how they tune motor response for a given application. Output current capacity and the 3.7 kW power rating make this unit suitable for loads such as small conveyors, pumps, fans, and compressors operating at or below that power threshold.

Distinguishing the CIMR-VUBA0018BAA from sibling models, the single-phase input configuration sets it apart from the majority of V1000 units in the family, which are specified for three-phase input; this makes the CIMR-VUBA0018BAA the preferred selection when only single-phase 240V supply is available at the installation point. The drive incorporates Yaskawa's closed-loop vector control capability alongside its open-loop V/f modes, a feature that differentiates it from the stripped-down J1000 series that lacks closed-loop feedback support. Built-in EMC filtering and a compact footprint allow the unit to be mounted directly inside standard control panels without supplemental filter hardware in many installations. For network integration, the Yaskawa CIMR-VUBA0018BAA supports optional communication cards enabling Modbus RTU, DeviceNet, and PROFIBUS connectivity, making it compatible with Allen-Bradley and Siemens PLC ecosystems as well as Yaskawa's own DriveWizard Industrial PC software for parameter management. Industries where this drive sees regular deployment include food and beverage processing lines, HVAC systems in commercial buildings, textile machinery, woodworking equipment, and small-scale water treatment pump stations. Facilities managers and OEMs sourcing drives for these environments will find the CIMR-VUBA0018BAA among our VFD repair catalog, which covers the full V1000 product line alongside other Yaskawa families.

Field service experience with the CIMR-VUBA0018BAA shows that the most frequently encountered failure modes include DC bus capacitor degradation after extended operating hours in high-ambient-temperature enclosures, IGBT module failure tied to repetitive overcurrent fault conditions, and gate drive board faults arising from voltage transients on poorly conditioned single-phase supply lines. Because the unit draws all input power through a single-phase connection, line voltage fluctuations and harmonic distortion tend to stress the internal rectifier bridge more than equivalent three-phase input models, making upstream line conditioning worth considering in environments with poor power quality. Fan bearing wear on the internal cooling fan is another age-related issue that commonly precedes thermal shutdown faults on older units. When evaluating a CIMR-VUBA0018BAA replacement after a failure, it is worth confirming whether the original fault was a component-level issue or a systematic problem such as an undersized drive for the actual load — an important step before sourcing a CIMR-VUBA0018BAA for sale or committing to a repair path. Technicians looking for documentation on fault code interpretation and parameter backup procedures can reference Yaskawa's published technical manual alongside our VFD repair services page, which covers diagnostic intake for this model.
