Commercial VFD Service
VFD Control Panel Integration
A VFD becomes part of a wider control system when it is integrated with a panel, PLC, HMI, SCADA, BMS, safety circuits and site operating modes.
Integration scope
- Drive panel layout and heat dissipation
- Power and control wiring segregation
- Analogue, digital and communications interfaces
- PLC, HMI, SCADA or BMS signals
- Bypass, isolation and operator controls where required
Control considerations
- Start/stop source and speed reference
- Local, remote, manual and automatic modes
- Fault reset and alarm philosophy
- Safe torque off and emergency-stop philosophy
- Parameter backups and change control
Documentation
- Wiring diagrams
- IO schedules
- Communication maps
- Parameter records
- Functional test sheets

What to include in your enquiry
For a faster technical discussion, send the site location, drive manufacturer and model, fault code if applicable, motor nameplate photo, motor power and full-load current, supply voltage, driven equipment type, panel photos, PLC or control-system details and any shutdown constraints.
FAQs
Common questions
Can a VFD be controlled by PLC or SCADA?
Yes, where the drive and control system are designed for it. Control can use hardwired IO or industrial communications depending on the application.
Should a bypass be included?
A bypass may be useful for some critical applications, but it adds cost and complexity. The need depends on the process and risk.
