Replacing a freqrol FRSX-2-11-K

[carbidecraters]

The drive is from a older QT10 we have here with a T1 control. Is it possible to replace with another 10hp spindle drive or do we have to get this one fixed. Are these propietary? What are our options

you can use 11kw VFD/Inverter with vector control, it's similar.
i have replaced in my machine, and working fine. i use Toshiba inverter.

Do you have a internet link? How much USD did you have into the inverter swap? I am trying to save this old heap before I throw it away

you can find www.meau.com
i change the spindle drive with toshiba inverter, just less than $900 , and i get 1 year warranty. and working fine about 3 years and nothing problem.

What model did you end up using? I may give them a call. Did you have the same Universal 10 Mazak that we have with the T1 controller? Was there much of a wiring difference? And lastly could you post a picture?

I use Toshiba VF-S11 11kw, but if your motor is 5.5Kw, you should use 7.5Kw.
Toshiba have same pin description with FRSX, and only 1 wire that connected directly with common ( Zero Speed Cable ).
You can choose the brand of inverter, depend your budget, all inverter connection are almost same.
don't forget, spindle encoder is not connected with the inverter and you can save it.

Wow what a great help! It turns out the local Toshiba rep is only 2 miles from our shop and is stopping by on monday!! I thought maybe the encoder may have had an issue as well because we had to splice the wires together after the cable rubbed on the belts. wow we are actually going to get this old beast running and running well! Thank you so much for the help and picture!

What is the black box you have on the inside side of the cabinet? Are you currently DNC'ing to your Mazak?

[nastek]

it's just cooling fan, Mazak cannot connect with ordinary DNC, i make program by hand.
it's simple, no need dnc.

Ok so the local Toshiba rep came and he said he will install 15hp unit and it will need to be wired. I dont have any wiring schematics. Do you have a pin out for the cables? And how many of the 3 plugs did you use on the unit? The Toshiba rep said they do not have plugs like the Mazak has.

Thank you so much for the help!

i have no detailed manual, you can download it.
i attached picture of VF-S11 Connection with Caption.
Red text are pins on FRSX.
no use encoder, keep it.
for RPM setting, you can use manual spindle rotation on 100% Scale.
and please remember the original FRSX's RPM. just like that.
You should use Braking resistor for deceleration.
use parameter F201 if your rotation can not reach the maximum RPM.
i think the Toshiba's engineer know it.
same like me, Toshiba's engineer installed mine.
hope this help.
sorry for my english.
