Open-source EtherCat Spindle Encoder using GDS32F407 and LAN9252

This code was developed for this board from AliExpress: This board has 8 LEDs and 8 switches connected to a GD32F407ZG. The GD32F407ZG has SPI and an FSMC bus to a LAN9252 which has the PHY and EEPROM ...

Problem with spindle synchronous encoder

The sender has set PULSE 100, encoder A is connected to PULSE, and Z is connected to INDEX. Of course, I also swapped them, and there was no change in the iOS speed after rotation. I also used an ...

A high-speed vector-controlled spindle motor drive with closed transition between with encoder control and without encoder control

Abstract: A 40000-r/min vector-controlled induction motor drive is introduced. The vector control of induction motors has been widely accepted in spindle drives of machine tools where they replace ...

Improve encoder performance

It’s easy to treat optical encoders as “black boxes” that need minimal consideration before they are installed to translate rotary motion into position or velocity feedback signals for a motion ...
