VFD Programming Technician – VPT
What is VFD Programming?
A Variable Frequency Drive (VFD) or Variable Speed Drive (VSD) is an electronic device used to control the speed, torque, and direction of AC motors by varying the frequency and voltage supplied to the motor. VFD programming is the process of configuring drive parameters, control terminals, protection systems, and operational modes to ensure safe, efficient, and reliable motor control in industrial environments. VFD systems are widely used in: Mining plants, water treatment systems, conveyor systems, food processing industries, manufacturing plants, pumping stations, and HVAC systems.
The VFD Programming Technician program is a hands on practical training focused entirely on configuring and commissioning industrial Variable Frequency Drives such as CNC VFD, Danfoss VFD, and Delta VFD systems.
Who Needs This Training?
This training is designed for industrial electricians, maintenance technicians, plant operators, engineers, and engineering students who want practical skills in motor speed control systems. It is ideal for anyone working with pumps, compressors, conveyors, fans, mixers, or any motor driven process that requires speed control and protection.
If you want to confidently wire, program, and troubleshoot industrial VFD systems without depending on PLC control, this training is for you.
