Manual operation of VFDs using a keypad, including changing speed and direction, startup, enablement, shutdown, and basic parameter viewing and editing. PLC-controlled 2- and 3-wire VFD operation, including interpreting PLC programs and wiring schematics, configuring VFD parameters, monitoring operation, and performing normal, emergency, and pause functions. Multi-speed operation, motor speed control, acceleration and deceleration, S-curve acceleration, braking, troubleshooting VFD errors, resetting drives after faults, and understanding the effects of frequency and VFD output on motor performance.
