The three ways to control a VFD from a PLC: discrete I/O, an analog speed signal, or a network. Wiring, drive settings and tips for each.
Why drives trip on overvoltage when stopping, how a braking resistor fixes it, the alternatives, and a worked sizing example.
A step-by-step way to tell whether a proximity sensor is bad, using the LED, a multimeter or a sensor tester, for PNP, NPN and 2-wire sensors.
Learn ladder logic from the ground up: rails and rungs, contacts and coils, latches, timers and counters, with a worked start/stop example.
Size a variable frequency drive by motor current, load type, supply and environment. Includes a worked example and a sizing checklist.
Yes, a VFD can turn single-phase power into three-phase for a motor. What you need, how to size it, wiring basics and the mistakes to avoid.
Step-by-step wiring for 2-wire and 3-wire proximity sensors, PNP and NPN outputs, and connecting them to a PLC, with troubleshooting tips.
