thanks to all people for the help.
The problem has been solve, replacing the encoder drive motor.
Thank you.

The fault almost certainly lies in the CPU.
You can try to replace it, otherwise it is a defect in a weld in the group of power IN-MOTION.

Ok, I'll try to check the footpedal output.
I'll tell you.
Thank you very much for your help.
Best regards
If i was to guess I would say either its a mechanical related issue perhaps or somehow related to your accelerator. If someone has the information perhaps they may know what the footpedal output should be at maximum sweep. Just out of curiosity what voltage wipe do you get at your accelerator unit?
The speed is correctly programmed, but the truck runs slow, there is no faults in display. I´ve changed the encoder sensor of traction motor, but also runs in the same way.
What do you think about it?
Thanks a lot for your anwers.
Best regards.
Has the truck suddenly developed this fault? Or is this a truck you have bought which just happens to be running slow?
The reason I ask is, incase it has been programmed to run at a slow speed.
