MEC 210 - Variable Frequency AC Drives

2 Credit(s)

Prerequisite(s): MEC 149

Course Description: Teaches variable frequency AC solid-state control of 3-phase electric motors. Learners develop knowledge in the operation, installation, performance analysis, troubleshooting, and design of AC solid state control using 2-wire, 3-wire, manual, and open-loop speed control. Highlights motor jogging and dynamic braking as well as programmable acceleration and deceleration.

Course Level: Career/Tech Preparatory

Course Learning Outcomes:

CLO#1: Identify variable speed AC drive systems and operate a motor using a programming keyboard.
CLO#2: Describe how frequency affects speed on an AC Induction motor. Demonstrate proper programming of a VFD.
CLO#3: Explain ramping, special acceleration and braking using variable AC drive.
CLO#4: Troubleshoot parameter and fault code. (ILO: Critical Thinking)
