Encoder Pulse Frequency Calculation: A Technical Guide

TL;DR: Specifying an encoder for motion control requires exact math to prevent PLC signal loss. Calculating the baseline encoder pulse frequency calculation ensures your High-Speed Counter (HSC) input card can keep up with maximum motor RPM, particularly when utilizing x4 quadrature decoding. The Physics of Encoder Pulse Frequency Calculation In motion control, mismatched hardware specifications […]

Inside PROFINET IRT: A Comprehensive Configuration Guide for Motion Control

When engineering high-speed motion control systems, standard real-time communication often falls short. In applications like robotics, CNC, or tightly coupled electronic gearing, a variance of a few milliseconds in communication can translate to mechanical collisions or significant product defects. Achieving precise coordination requires a hardware-synchronized, deterministic network architecture. This is where PROFINET IRT configuration comes […]

How-To: Calculating Servo Motor Inertia Ratio for High-Speed Indexing

When an industrial automation engineer sizes a servo motor for a high-speed indexing application, simply matching the torque and speed requirements is a recipe for disaster. If the inertia of the driven load vastly exceeds the inertia of the motor rotor, the servo system will struggle to control the load dynamically. This mismatch results in […]
