1Vpp Encoder to Mesa 7i33

yes, Iam developing a HAL component for Hiperface. Sure I can provide it when finished.

The code is very rough now, but Iam able to read absolute position and some other status information too. Since its only 9600bd RS485 interface it can not be used for 1ms servo loop, but just for commutation setup after power on.

I plan to use 7i44 serial interface for encoder connection. Lately I could use some help with customization of 7i43 firmware for UART communication with selected port(s). I tried firmware compilation with Webpack 9.2i, but Iam not sure if done correctly. Maybe some sample of prj file could help.

I just finished the IC-NV chip for sin/cos interpolation initial testing. It proved its functionality for 16-fold interpolation.

Iam going to design a production PCB.

If anyone is interested having sin/cos encoder needs to be quadrature signals, please let me know. I can therefore design PCB with universal features.

Briefly about ic-nv. For 16-fold interpolation, max. input frequency is 200kHz. For instance you can have servo with 3000RPM, 2048 sin/cos encoder, in total 2048 * 16= 32768 * 4 = 131072 PPR, which is insane!

Pavel have you made this pcb's fo IC house interpolator? I would be interested

Hi,
it’s possibile have the pcb project?
i have some trouble with heidenhain liner scale
LC 483...

If you want to use a small board you can use this chinese adapter boards and and a simple experimental
PCB with some Resistors and jumpers.


I think, you cant beat this price with an individual made PCB.

Sorry, the false ev-Board
Here is the right, but the other have the same, what you get with the chinese adapters.
