HMI Repair & Electrical Drive Troubleshooting
When You Lose Control, You Need a Team That Gets It Back—Fast.
When your HMI or drive system goes down, your entire operation can grind to a halt. That’s when you need fast, intelligent service.
At Altech Process and Control, we specialize in on-site repair and troubleshooting of Human-Machine Interfaces (HMIs), variable frequency drives (VFDs), and servo drives. Whether it’s a touchscreen failure, communication dropout, power issue, or drive fault, we get to the root cause fast.
We work with:
New and obsolete HMIs and drives
Servo and VFD systems in CNCs and industrial automation
Allen Bradley, Siemens, ABB, FANUC, and more…
High-accuracy automation equipment
You call. We show up. We fix it.
No fluff, just expert troubleshooting that gets you running again.
Signs Your HMI or Drive Needs Immediate Attention:
Frozen or unresponsive touchscreen displays
Erratic machine behavior or control loss
Servo motor faults or inconsistencies
Alarm codes without clear explanations
Display, sensor, or feedback errors
Failure to load or communicate with PLCs or CNCs
If you’re experiencing any of these, don’t wait for it to get worse. A minor HMI glitch today could become a full shutdown tomorrow.
Common HMI and Drive Issues We Solve:
Cracked or non-functioning HMI screens
Software corruption and control system reboots
Sensor errors and calibration faults
Electrical drive failures in servo systems
Faulty power supply units
Motor control inconsistencies
Data communication breakdowns between HMIs, PLCs, and CNCs
Overheating or thermal shutdowns in drive enclosures or control cabinets
