Engineering experience that connects the whole machine
A machine fault can involve several systems at once. An axis that loses position may need its drive, feedback and mechanical condition investigated. A machine that stops during an automatic cycle may be waiting for a sensor, a drive status or a response from connected equipment.
PMI brings the machinery and its control system into the same investigation. We trace the reported symptoms through the equipment involved, drawing on experience in:
- CNC and machinery fault finding — investigating operating faults, recurring alarms and interrupted machine sequences.
- PLC, HMI and control software — understanding machine logic, inputs, outputs and software behaviour, including TwinCAT and CODESYS environments.
- Servo drives and motion control — investigating drive alarms, motor-feedback problems, homing faults and positioning errors, with experience using IndraWorks, DriveTop and Siemens STARTER drive software.
- Industrial networks — diagnosing EtherCAT, PROFINET and communication problems between controllers, drives and I/O.
- Maintenance and machinery projects — applying equipment knowledge to servicing, installation, relocation and changes to existing machinery.
This combination helps us explain what is affecting your machine, identify the work required and assess replacement components in the context of the complete system.

Brands and systems we work on
Our experience includes the following machinery manufacturers, automation systems and vacuum-pump brands.
PMI provides fault finding, servicing and maintenance for HOMAG woodworking machinery, backed by practical CNC and automation experience.
We investigate recurring alarms, interrupted machine cycles and movement faults, and support machinery installation and relocation projects. Understanding the controls, electrical equipment and mechanics together helps us investigate problems across the complete machine.
Explore HOMAG machinery support →Specialist support for Beckhoff machine-control systems, TwinCAT software and EtherCAT networks.
Whether the PLC is running but the machine will not move, an I/O device has stopped communicating or an EtherCAT device remains in SAFE-OP, PMI investigates the control sequence, device diagnostics and configuration.
We also handle Beckhoff component-sourcing enquiries, using the full part number, revision and application to assess the requirement.
Explore Beckhoff and TwinCAT support →Practical experience with Bosch Rexroth drives and motion-control systems, including IndraDrive, alongside experience using IndraWorks and DriveTop software.
Contact PMI about drive alarms, axes failing to home, motor-feedback faults or a servo drive that will not enable. We bring fault investigation and replacement assessment together, considering the drive, motor, feedback and machine configuration.
For a Rexroth component enquiry, send the complete type code and any associated motor or module details.
Explore Rexroth and IndraDrive support →Engineering support and component-sourcing enquiries for Inovance automation, servo-drive and motor applications.
Whether you need help with a drive fault, a replacement servo motor or a drive-and-motor combination, PMI reviews the equipment in its machine context. We consider the connected controller, motor feedback and communication interface when assessing the requirement.
Explore Inovance engineering and parts support →Busch vacuum pump experience covering planned servicing, fault finding, repair and overhaul.
If your pump is losing vacuum, overheating, becoming noisy or stopping unexpectedly, PMI investigates its condition and the machinery it serves. We plan the work around the pump model, operating duty, service history and production requirements.
Explore Busch vacuum pump servicing →Becker vacuum pump servicing and fault finding supported by wider CNC and machinery knowledge.
PMI helps with reduced vacuum performance, unusual vibration and planned maintenance. We assess the pump alongside its installation and inspect the relevant service components, including filters and vanes where fitted, to establish whether servicing, a targeted repair or a more extensive overhaul is appropriate.
Explore Becker vacuum pump servicing →Parts sourcing backed by engineering knowledge
Need a replacement PLC, servo drive, motor, I/O module or industrial PC? Send the manufacturer and full part number, or a clear photograph of the equipment label.
PMI combines component sourcing with an understanding of the machinery around the part. We consider the relevant specifications, interfaces, feedback and configuration when assessing a replacement, and confirm suitability and availability for the specific requirement.
For older machinery, we can investigate obsolete automation parts and assess the options for sourcing the original item or making an engineered replacement.
Questions about our engineering experience
Can PMI help when a machine contains equipment from several manufacturers?
Yes. Our CNC and automation experience helps us investigate how controllers, drives, motors, I/O and machine signals work together. Send the machine model and the control or drive details you have so we can review the installed system and the help required.
Can I enquire if I only have a fault code or a photograph?
Yes. A clear photograph of the machine identification plate, component label or fault screen is a useful starting point. Explain what the machine is doing, when the problem occurs and whether anything changed before the fault appeared.
Where does PMI provide engineering support?
PMI is based in Craigavon, County Armagh, and provides engineering support across Northern Ireland and the Republic of Ireland. Include your site location and required timing so we can discuss the work and attendance arrangements.
Put our experience to work on your equipment
Tell us what your machine is doing, which component you need or what you want to change.
Send the equipment identity, site location and required timing, together with any useful fault codes, photographs or part numbers. We will review the requirement and discuss the next step with you.
