Control & Drive Repair Service | UAE
PLC, VFD and servo drive repair service in Dubai, Sharjah and across the UAE.
Fast, practical repair support for automation breakdowns and unstable control performance in facilities worldwide, with UAE and GCC on-site support. We diagnose and repair PLCs, HMIs, VFDs, servo drives, motor control systems and control panels for major industrial brands including Siemens, Schneider Electric, FANUC, Allen-Bradley, ABB and others.
Supported Brands
Multi-brand expertise
Siemens & Schneider
PLCs, HMIs, drives and controls
FANUC & ABB
Drive and motion platform support
Allen-Bradley

On the bench
Structured diagnostics before parts are replaced.
We isolate root cause on PLCs, HMIs, VFDs and servo systems with bench testing, parameter review and documented fault analysis — so repairs fix the failure, not just the symptom.

Repair Scope
Complete service for control and drive reliability.
We combine electrical, controls and process expertise to restore uptime quickly and reduce repeat failures.
Fault Diagnostics
Root-cause analysis for intermittent trips, communication faults, overheating, harmonics and unstable control loops.
PLC & HMI Recovery
Program backup/restore, I/O mapping corrections, alarm logic cleanup, HMI screen recovery and firmware compatibility checks.
VFD & Servo Drive Repair
Drive parameter correction, tuning, encoder feedback validation, braking/chopper checks, motor-drive matching and commissioning.
Control Panel Retrofit
Panel reconditioning, component replacement, terminal rewiring, protection coordination and modernization of legacy hardware.
Emergency Breakdown Support
Rapid-response troubleshooting with clear action plans to restore operation and stabilize production safely.
Preventive Reliability Program
Planned inspections, thermal checks, parameter audits, spare strategy and maintenance reports to prevent unplanned shutdowns.
Representative work
Typical control and drive repair paths we handle on site and in the workshop.
Illustrative service patterns — not a client portfolio. Every repair is scoped to your brand, fault codes and production impact.

FAQ
Questions plant engineers ask
Practical answers on PLC and drive repair — from Sharjah, for plants in the UAE and GCC.
Do you repair VFDs, PLCs and servo drives?
Yes. Diagnostics and component-level repair for Siemens, Schneider, FANUC, Allen-Bradley, ABB and related equipment, with UAE support.
Repair or reverse-engineer?
Repair first when the module is serviceable. Reverse engineering when the board is obsolete and no spare exists. We advise which path is faster for uptime.
Do you work on site in the UAE and GCC?
Yes. SAS Middle East FZC is based in Hamriyah Free Zone, Sharjah. We survey, engineer and commission PLC and drive repair on site across the UAE and GCC.
