Yes. A complete variable frequency drive installation includes drive-to-PLC integration over EtherNet/IP, Modbus TCP or PROFINET, plus HMI graphics, alarms and trend setup. VFD commissioning verifies data exchange between the drive and the broader control system before the drive is released to production.
Network and HMI integration tasks during VFD commissioning:
- PLC tag mapping: Engineers map drive control words, status words, speed reference and feedback to PLC tags for use in process logic.
- Communication protocol setup: EtherNet/IP, Modbus TCP, PROFINET and CANopen each have different timing, addressing and electronic data sheet (EDS) requirements that must be configured on both ends.
- HMI graphics and alarms: Drive status, fault codes, speed feedback and motor current populate the operator interface so production staff can run and troubleshoot without a laptop.
- Trend logging: Drive parameters can be logged to the PLC or historian for energy reporting, predictive maintenance and root-cause analysis.
- Safety integration: If the drive is part of a safety-integrated system, then commissioning includes verification of safety function exchange between the drive’s STO inputs and the safety PLC.
