The FANUC A860-0203-T013 is a Manual Pulse Generator (MPG), commonly known as a handwheel or pendant. It's a portable, handheld control unit used for the manual, precise positioning and adjustment of machine axes on CNC (Computer Numerical Control) equipment like milling machines and machining centers.
Application: Designed for 4-axis control, typically labeled as X, Y, Z, and a 4th axis, and is well-suited for milling applications
Display: Features an integrated LED display to show axis positions and other operational information
Design: A pendant-style, portable unit with an ergonomic design for hand-held operation
Compatibility: Specifically designed for seamless integration with FANUC CNC systems
Power Supply: Requires a 24 V DC power supply
Purpose & Application
The primary function of the A860-0203-T013 is to enable an operator to manually move the machine's axes with high precision. By turning the handwheel, the operator sends precise electronic pulses to the CNC controller, allowing for fine adjustments down to a very small increment (e.g., 0.001mm), which is essential for setup, tool alignment, and manual machining operations. It acts as a direct, tactile interface between the operator and the machine.
