How to get 400KHz operation with UC300-5lpt unit

[innovativeI1959]

Hello,

I am trying to get the 400KHz option on UCCNC software for my Mori Seiki Retrofit, but the software only shows 100KHz option as the maximum.
The manual indicates that it can achieve 400KHz operation.

Can you please advise ?

Thank you in advance

Do you have a USB UC300, or the UC300-ETH?

If it's a USB UC motion controller 100khz is the fastest internal loop speed due to the microcontroller I believe.

that would be the UC100 and the UC300 5LPT USB

The ethernet motion controllers UC400ETH, UC300ETH, and AXBB-E all are listed as having a selective loop speed up to 400khz

Hello,

Yes it is the USB UC motion controller.

Thank you

for the advanced functions required for a mori your going to want the ethernet version. as you will require spindle sync, threading etc etc.
the usb version doesnt have enough memory for all the functions.
i have the uc300eth on my mill and threading/ encoder tracking etc work great
