PLC jog logic, simplified: the jog button runs the motor only while it's held — no seal-in, so releasing it stops the motor instantly. The run-while-held rung. Here's how.
⚡ QUICK ANSWER
Jog logic is the simplest motor rung: the motor runs only while the jog button is held. Unlike a start-stop circuit, there's no seal-in — no contact latching the output on — so the moment you release the jog button, the rung goes false and the motor stops immediately. That's the whole point of jog: momentary, run-only-while-held control for inching a machine into position or bumping it a little at a time. In ladder logic it's often a single, clean rung — the jog input driving the motor output directly, with nothing holding it. Because there's no latch, it can't run away on you; let go and it's off. Here it's shown against the ACC Simulator's Control Panel scene, so you can watch the motor run only while jog is pressed. The full walkthrough is in the guide below.

📚 WHAT YOU'LL LEARN
✅ How jog logic runs the motor only while the button is held
✅ Why there's no seal-in — so releasing jog stops the motor instantly
✅ How the jog input drives the output directly in a single rung
✅ Why jog is used for inching a machine into position
❓ FREQUENTLY ASKED
Q: What is jog logic in a PLC?
A: It's a rung where the jog button runs the motor only while it's held — there's no seal-in, so releasing the button stops the motor immediately. The full walkthrough is in the guide.
Q: How is jog different from start-stop?
A: Start seals the motor in so it keeps running after you release the button; jog has no seal-in, so the motor runs only while jog is held and stops the instant you let go.
