Comprehensive Analysis of Relative and Absolute Positioning in Mitsubishi PLCs: A Practical Guide to Stepper/Servo Motor Control

1. Core Concepts of Positioning Control 1. Relative Positioning (Incremental Positioning) Definition: Move a specified number of steps based on the current position Instruction: PLSY (Pulse Frequency Output) – Requires manual origin point recording – Suitable for repeated relative movements – Weaker anti-interference capability 2. Absolute Positioning (Absolute Positioning) Definition: Directly move to a preset … Read more

Understanding Pulse Control in PLC for Servo Motor Positioning

by

PLC sends pulse signals to control servo operation. One of the most challenging aspects is how the pulses sent by the PLC (i.e., the position set in the PLC) correspond to the distance the servo moves the mechanical system.Here, I will explain this in the simplest way possible.1. Before discussing the method, it is essential … Read more
