TNC-G09 : Drill Cycle Controller
Single-axis drill cycle controller with four timed 24 V relay outputs and differential step outputs.
Overview
The TNC-G09 runs a drilling cycle on a single axis, and its value is in the sequencing rather than the motion.
Four 24 V relay outputs each take a settable delay before cycle start. That covers the things that must happen around a drill cycle and in the right order — coolant on, clamp closed, guard confirmed — without a separate PLC to coordinate them.
The axis drives through differential outputs, which will run a stepper or a servo drive. Differential signalling matters more than it sounds on a drilling machine: the pulse train runs alongside contactors and motor cables, and a differential pair rejects the noise that a single-ended output would pick up as false steps.
External inputs are provided for emergency stop, start/stop, safe height and home. Operation is through a 20 × 4 character LCD with menus intended to be usable by an operator rather than a programmer.

Questions
What are the four relay outputs for?
Sequencing the machine around the drill cycle — coolant, clamping, guarding and similar. Each has a settable delay before cycle start, so the order and timing are configured rather than wired.
Can it drive a servo?
Yes. The axis output is differential and will drive a stepper drive or a digital servo drive.
Why differential outputs rather than single-ended?
A differential pair rejects electrical noise. On a drilling machine the pulse train runs near contactors and motor cables, and single-ended signalling is where false steps come from.
