Mitsubishi iQ-F FX5U PLC

Built-in High-Speed Counter Functionality & PLC interaction with encoder using pulse density.

Introduction

Just some additional information the Encoder interfacing to the Melsec iQ-FX5U PLC – please note that the following function blocks is essential to be incorporated within the PLC program;

If one requires to read pulse-density (an application of encoder feedback); Below some PLC programming blocks this purpose;

As for the High-speed counter settings – the following was applicable;

Some information regarding high-speed counters (which is normally used in conjunction with encoder feedback.) – A standard CTU can be used temporarily for that purpose;
