Set the electronic gear. Refer to [Pr. PA06] for the settable values. In the cyclic synchronous mode ,
setting Motor revolutions (6091h: 1) or Shaft revolutions (6091h: 2) to anything other than "1" will trigger
[AL. 37].
Gear ratio (6091h) =

No value can be written because Feed (6092h: 1) and Shaft revolutions (6092h: 2) are set automatically
with the control mode, [Pr. PT01] and [Pr. PT03]. Writing any value causes SDO Abort Code (0609
0030h Value range of parameter exceeded).
This object is available with drivers.
