so, i need your help in the following :

1-what this error mean
2- how to do cold start to axes
3- is it possible to change the language to English?

All of the information you requested should be in your manuals for this machine. If you do not have the manuals, you should purchase them.

Error #26 is an overload in jog mode. This could be a weak amplifier or motor. Perhaps there is some excess mechanical drag in gibbs, straps or ball screw.
Can you operate the machine if you turn down to rapid overload selector to 50% or 25%?
