Gear ratio Setting (6091-01 and 6091-02 Hex)
*1  The encoder resolution is set as the numerator for fully-closed control. 
Precautions for Correct Use
 To make the position command smoother after the electronic gear setting, adjust it by using the
Position Command Filter Time Constant (3222 hex) or by the Position Command FIR Filter Time
Constant (3818 hex).

When the Motor revolutions (6091-01 hex) is 0, the processing changes 
with the set value of Shaft revolutions (6091-02 hex).
Position command = Encoder resolution/Shaft revolutions (6091-02 hex)
