trouble right motor 4DOFbase

[dsaid]

Good day!
On the 4DOFbase device we have, the right axis works 2 times less than the left one,
While on the display of the frequency converter of the left engine the figures (revolutions?) Are half the right.
When calibrating the bed frame, both axes (left and right) are raised o at the same time (with the same numbers on the display of their frequency converters). The problem arises directly in the game (thinking about the wrong data from the steering wheel) and when changing the roll / pitch parameters (here the steering wheel is not activated).

Thanks

Probably problemma in the software part, in view of the fact that when calibrating (up / down), both engines (left and right) operate synchronously
