Why Repair WEG Equipment?

Replacing a WEG drive, controller, soft starter, or other automation component is not always a straightforward swap. Existing equipment may contain application-specific parameters, motor settings, communication configurations, or control programming that need to remain compatible with the machine.

Repairing the original equipment can help:

• Reduce replacement costs
• Avoid equipment sourcing delays
• Preserve existing machine settings
• Maintain compatibility with installed motors and controls
• Support older or discontinued WEG equipment
• Reduce programming and commissioning work
• Limit production downtime
• Avoid unnecessary machine modifications

For machinery that is already configured and operating properly, repairing the original component can often be a less disruptive alternative to replacement.

Repairing an existing drive may allow the machine to remain configured around its original control platform instead of requiring a larger equipment change.

WEG Servo Drive Repair

WEG servo drives are designed for applications requiring precise speed, torque, synchronization, and positioning control. WEG’s SCA06 and SCA700 platforms provide servo control capabilities for three-phase servo motors, with applicable systems supporting feedback devices such as encoders or resolvers.

AES repairs applicable WEG servo drives experiencing:

• Servo will not enable
• Positioning errors
• Encoder or feedback faults
• Communication failures
• Overcurrent alarms
• Internal power supply problems
• Output-stage failures
• Intermittent servo faults
• Loss of synchronization
• Excessive motor or drive faults

The exact repair approach depends on the servo drive model, failure symptoms, and condition of the internal electronics.

WEG SCA06 & SCA700 Servo Drive Repair

AES can evaluate applicable WEG SCA06 and SCA700 servo drives for electronic and operational failures.

Common issues may include:

• Loss of motor control
• Positioning problems
• Feedback errors
• Communication faults
• Power failures
• Output-stage problems
• Internal component failures
• Overheating
• Intermittent operation

WEG identifies the SCA06 as a servo drive capable of speed, torque, and position control, while the SCA700 provides additional motion-control capabilities through its integrated SoftMotionPLC functionality.

When requesting service, provide the complete model number along with any fault codes or information displayed by the drive.

WEG Soft Starter Repair

WEG soft starters are used to control the starting and stopping of three-phase induction motors while helping reduce the mechanical and electrical stresses associated with direct starting. The WEG SSW07 is one example of this product family and includes motor protection, bypass functionality, and optional communication and interface features.

AES evaluates applicable WEG soft starters experiencing:

• Failure to start
• Failure to stop correctly
• Overcurrent faults
• Phase-related faults
• Control problems
• Communication failures
• HMI or keypad problems
• Internal power supply failures
• Thyristor or power-stage problems
• Overheating
• Intermittent operation

The specific repair requirements depend on the soft starter model and the source of the failure.

WEG SSW Series Soft Starter Repair

AES provides evaluation and repair support for applicable WEG SSW Series soft starters.

Potential repair issues include:

• No power
• Motor will not start
• Excessive starting current
• Phase-control problems

• Damaged power components
• Control-board failures
• Overheating
• Internal electronic faults

When requesting service, provide the complete SSW model and any fault information available from the unit.

WEG Motor Repair

WEG manufactures a broad range of industrial motors, including the W22 family of TEFC cast-iron motors and specialized motor designs such as W22 brake motors and W22 Magnet permanent-magnet motors.

AES can evaluate applicable WEG motors and motor-related electronic equipment for repair needs involving:

• Motor-control problems

How WEG Repairs Are Handled

WEG drives, soft starters, servo systems, controllers, and other automation products contain multiple electronic systems. A fault that appears simple from the outside may have a more complex underlying cause.

Depending on the equipment and failure, repair capabilities can include:

• Component-level fault isolation
• Power supply testing
• Control-board troubleshooting
• Power-stage inspection
• Communication circuit testing
• Electronic component replacement
• Cooling-system evaluation
• Motor and drive electronics testing
• Functional testing
• Final quality inspection

Every repaired unit is tested before it is released. The equipment is not simply powered on and shipped back. Applicable testing is performed to verify that the repair has addressed the identified problem.

Repair Support for Older WEG Equipment

Older WEG drives, motors, soft starters, controllers, and automation components can remain in service for years as part of established production machinery. When an original WEG component becomes difficult to source, replacing it with a newer platform may require:

• Parameter conversion
• Wiring changes
• Control-program updates
• Communication changes
• Motor or feedback modifications
• Machine recommissioning
• Changes to mounting or installation arrangements

AES evaluates applicable legacy WEG equipment to provide another option before making larger changes to an established machine.

Send the complete model number, part number, and serial information whenever possible. A clear photo of the equipment nameplate can also help with the evaluation.
