Roland 202 maximum speed restricted

Our Roland R202 1990 can't run faster than 9000 cycles/hour.

Looks like max speed was limited electronically.

There is a potentiometer or something like to raise the max speed?

Could someone please explain how to fix this?

Thanks.

 

In the main cabinet, where all the electronic boards are, there is a big panel at the bottom (4U1), that is the panel that controls the speed of the press.
On the mother board (top board), there should be two small potentiometers next to each other that say "min" and "max". one is for minimum speed (min) and the other is for maximum speed (max). Be very careful when you adjust, as the potentiometer is very sensitive.

I found eight small potentiometers on the board:



The only one that say "max" is the 01. I dont see the one that says "min".

You are able to recognize where they are in this photo please?

Thank you.

 

It is the adjustable resistor R241 (Nmax), I believe that would be number (6) in your picture.

Bingo. We are now running 11000 sh.

Thank you very very much!
