WEG EUCFW110024T40FAZ | Industrial Variable Speed Drive

Description

Core Product Summary (Brand / Model / Key Attributes)

The WEG EUCFW110024T40FAZ is a CFW11-series variable frequency drive rated for 11 kW / 15 HP three-phase induction-motor control at 380–480 V AC. Its CFW11 0024 T4 rating corresponds to a 24 A continuous output current.

The drive controls standard three-phase asynchronous motors using V/f control, VVW voltage-vector control, and closed-loop vector control. It also supports WEG Magnet permanent-magnet synchronous motors through the applicable CFW11 control configuration. The EUCFW110024T40FAZ includes a standard Modbus RTU interface and supports optional communication plugins for protocols such as PROFIBUS DP, DeviceNet, CANopen, EtherNet/IP, and BACnet, depending on the installed option module.

Key Technical Specifications

Detailed Product Overview

The WEG EUCFW110024T40FAZ is a CFW11 frequency inverter configured for an 11 kW, 24 A, 380–480 V AC application. It converts fixed-frequency mains power into variable voltage and frequency for speed and torque control of a three-phase motor. The CFW11 platform is designed for both standard induction motors and WEG Magnet permanent-magnet synchronous motors.

The drive supports several control strategies. V/f control is suitable for general-purpose machinery where simple speed regulation is required. VVW voltage-vector control provides improved low-speed torque behavior without requiring an encoder. Vector control supports closed-loop operation with an encoder and is used where precise speed or torque regulation is required. For vector control, the connected motor’s rated current must be equivalent to the CFW11 rated current to obtain the best possible torque-control accuracy.

The EUCFW110024T40FAZ includes Modbus RTU as its standard network interface. Optional plug-in communication modules extend integration to industrial networks including PROFIBUS DP, DeviceNet, CANopen, EtherNet/IP, and BACnet. This makes the drive suitable for PLC-, DCS-, and building-automation-connected systems, provided the installed plugin and firmware support the selected protocol.

The CFW11 provides programmable digital and analog I/O, relay outputs, motor thermal protection, and configurable fault and alarm behavior. Parameters can be set from the optional HMI keypad, through communication, or with WEG configuration software. The standard CFW11 version identified by the Z suffix is supplied without an HMI keypad; a keypad can be added where local operation and parameter access are required.

Installation must follow the CFW11 user and installation manuals. The drive is intended for installation in a protected enclosure or electrical room, with correct cable sizing, grounding, shielding, cooling, and input-power protection. Firmware can be updated through the USB interface using WEG WFD software, but the update process must not be interrupted.

Engineering Selection Highlights

• The EUCFW110024T40FAZ is rated 24 A and 11 kW / 15 HP at 380–480 V AC, so motor full-load current and supply voltage must fall within the drive’s rating.
• It is a CFW11-series drive for three-phase induction and WEG Magnet PM motors, so the motor type and control method must be selected during commissioning.
• V/f, VVW, and vector-control modes provide different performance levels, with vector control requiring appropriate motor data and, where applicable, encoder feedback.
• Modbus RTU is standard, while PROFIBUS DP, DeviceNet, CANopen, EtherNet/IP, and BACnet require the appropriate optional plugin.
• The Z suffix identifies a standard CFW11 configuration without an HMI keypad, so local keypad operation requires adding the appropriate HMI accessory.
• Programmable I/O and relay outputs allow integration with machine interlocks, start/stop controls, speed references, and status signaling.
• Cabinet installation must provide adequate cooling, EMC wiring practice, and protection against dust, moisture, and conductive contamination.

System Compatibility & Integration Requirements

Dimensions, Mounting & Connection Notes

• Install the CFW11 in a protected enclosure or electrical room; the standard drive is IP20/NEMA 1 depending on configuration.
• Provide sufficient clearance for ventilation and follow the CFW11 installation manual for the installed frame size.
• Use correctly sized power cables, control cables, grounding conductors, and input protection according to the CFW11 installation manual and local electrical code.
• Separate power and control wiring; use shielded cable and proper grounding practice for analog signals, encoder feedback, and communication wiring.
• Confirm motor cable length, carrier frequency, output filter, and EMC requirements before final installation.
• Verify that the DC-bus voltage has discharged before touching power terminals after removing supply power.
• Do not connect supply power to the motor-output terminals.

Verification & Troubleshooting Notes

• Verify the complete nameplate: model, rated current, input/output voltage, serial number, firmware version, and installed options.
• Confirm that the motor full-load current does not exceed the drive’s 24 A rating and that the motor data entered in the drive matches the actual motor.
• If the drive will not start, check the enable/run command, speed reference source, digital-input configuration, and active interlocks.
• For vector-control applications, verify motor nameplate data, encoder feedback, cable shielding, and motor/drive current matching.
• For communication faults, check the installed plugin, network address, baud rate, termination, wiring polarity, and protocol selection.
• For overcurrent or overload faults, inspect the motor cable, motor condition, mechanical load, acceleration ramp, and duty cycle.
• Do not interrupt power during a firmware update; an interrupted update can leave the drive inoperable.
• Follow lockout/tagout procedures and wait for DC-bus discharge before working on power terminals.
