Position actual value (6064h) is calculated from Gear ratio (6091h) and Feed constant (6092h), as
follows.
Position actual value (6064h) =
Position actual internal value (6063h) × Feed constant (6092h)
Position encoder resolution (608Fh) × Gear ratio (6091h)
When the unit is degree, the operation result will be limited within 0 to 359999.

No value can be written because SI unit position (60A8h) is 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).
