Hello,

I have recently purchased an Excitech router, with DSP and HSD spindle.
I came to an issue where i cannot command the spindle driver with the speed of spindle in Gcode. It only runs at maximum (300Hz/18k RPM). Does the DSP handle puts only on/off signal to the driver? How are you working with different speeds?

Thank you for your help,

You can change Spindle speed through the inverter keypad.

Scroll down to the " How to operate the Excitech " thread. There is plenty of info about it there.

Hi Rocket,

Thank you for your reply, i have spent half a day searching for information on this item.
Fortunately i have somehow solved the problem: the DSP works with 6 speeds preset(it can be changed in the menu) and each speed number is related to some binary 3digit number which can also be configured in the menu. For speed S1 i get 50Hz (3000RPM), for S6 i have 300Hz(18000RPM), this is good enough for me. It requires however changing the tool database in CAM.

thanks,
