Product Overview

The Yaskawa CIMR-VU4A0011FAA is a V1000 compact vector variable frequency drive for 380-480 VAC three-phase installations. Its dual rating provides 7.5 HP at 11.1 A in Normal Duty operation and 5 HP at 9.2 A in Heavy Duty operation. The substantial difference between the two horsepower ratings makes correct duty selection especially important for this model.

Normal Duty is primarily intended for variable-torque or moderate-overload loads such as centrifugal pumps and fans. Heavy Duty provides a higher short-term overload capability for conveyors, mixers, machine tools, process equipment and other constant-torque machinery. The motor nameplate current must remain within the applicable drive-current rating under the actual ambient, carrier-frequency and installation conditions.

• V/f control for conventional motor-speed regulation
• PM Open Loop Vector mode for compatible PM motors
• Normal Duty overload capacity of 120% for 60 seconds

• Integrated braking transistor for external resistor connection
• Programmable I/O and serial communication for automation integration

Technical Specifications

Compatible System and Applications

This drive can be integrated into standalone machine-control panels or PLC-based automation systems. Run direction, reset, multi-step speed, analog speed reference and status outputs can be configured through the available terminals. Serial communication can be used where centralized parameter access or command exchange is required. The correct grounding, shielding and cable-routing practices are important when the installation contains encoders, analog instrumentation or other noise-sensitive equipment.

Typical applications include pumps, fans, belt conveyors, packaging systems, mixers, process skids and general production machinery. For constant-torque loads, use the 5 HP Heavy Duty rating unless a detailed load calculation supports another selection. For pump and fan applications, confirm the minimum speed, motor cooling and process-control requirements.

Maintenance and Replacement Notes

When replacing CIMR-VU4A0011FAA, confirm the complete suffix because similar V1000 codes may have different enclosure, regional or configuration characteristics. Record the existing parameter file and terminal wiring before removal. Check the motor winding resistance, insulation condition, grounding, output cable and mechanical load if the previous drive failed with overcurrent, ground fault or overload indications.

If the machine is being upgraded to GA500, use the corresponding 400 V class drive selected by output current and operating duty. Parameter conversion can reduce commissioning time, but it does not replace an engineering review of safety wiring, I/O logic, communication options, braking hardware and motor tuning.

Related Models

Related models include CIMR-VU4A0009FAA, CIMR-VU4A0018FAA and CIMR-VU4A0023FAA. CIMR-VU4A0009FAA is the next smaller rating, while CIMR-VU4A0018FAA provides higher continuous current. Confirm panel dimensions and thermal requirements when changing the drive capacity.
