AC Variable Frequency Drive Training System Plus

Model: 429E

DAC Worldwide’s AC Variable Frequency Drive Training System Plus (429E) examines AC variable speed drive principles. Learners will explore variable frequency AC solid-state control of 3-phase electric motors in various automation applications. The trainer also covers industry-relevant skills, such as AC drive programming, drive system troubleshooting, and control wiring in a variety of applications.

This AC Variable Frequency Drive Training System includes an industrial 3-phase motor, a three-pole circuit breaker with lock out/tag out, twenty-nine (29) banana jacks, and much more. Learners will use these components to study topics such as minimum and maximum frequencies, plotting the ramping characteristics, programming AC Drive outputs, and troubleshooting.

This system utilizes industry-grade components, providing durability to stand up to frequent use while aiding learners in becoming better prepared for the tasks they will encounter on the job. Whether it’s used as a stand-alone training device or in combination with other automation-related training products, this device will help make training in this fundamental technology more informative and productive.

Practice Hands-On Electrical Skills for Various Applications

This AC Variable Frequency Drive Training System features a portable, benchtop mount, including a welded tubular aluminum baseplate with rails for mounting a 56-frame motor. All I/O and control wiring capabilities of the Allen-Bradley, PowerFlex 40 drive are accessed using banana jack connections on the front panel face. Additionally, eight fault switches are provided on the back of the electrical enclosure allowing for drive, motor, and control wiring troubleshooting.

This trainer, however, centers on the Allen-Bradley PowerFlex 40 variable frequency drive, which creates working voltages of 115/220 VAC. It features a remote potentiometer input with adjustable frequency. There are three inputs (voltage, resistance, and amperage), as well as three outputs (voltage, relay, and amperage). It also features eight (8) inputs for PLC data, and a programmable acceleration/deceleration with an on-board PID control loop.

Learners will use these components to practice hands-on skills, such as checking the nameplate data, performing pre-power checks/start up, programming over current safety features, setting acceleration/deceleration timing, and an introduction into troubleshooting AC motors.

In addition to standard courseware curriculum, the trainer comes with eight (8) instructor fault switches in the rear of the device, allowing students to practice real-time troubleshooting skills.

Hands-On Exercises and Learning Activities Lead to Realistic Results

DAC Worldwide’s AC Variable Frequency Drive Training System also features exercises and learning activities that focus more on results and less on secondary academic background information. This comprehensive training system offers learning over specific automation skills, including: Variable Frequency AC Drive Theory, Electrical Connections of the Allen-Bradley PowerFlex 40, Checking and Setting Jog Parameters, Using External Voltage and Current Sources of Motor Control, and much more. The integrated course includes a total of 26 activities, all of which include background information on the topic, hands-on experiments, and related review questions.
