No value can be written because Feed (Class ID: 64h, Ins ID: 6092h, Attr ID: 1) and Shaft revolutions
(Class ID: 64h, Ins ID: 6092h, Attr ID: 2) are set automatically with the control mode, [Pr. PT01] and [Pr.
PT03]. Writing a value sets a general-purpose code 09h Invalid attribute value.

Position actual value (Class ID: 64h, Ins ID: 6064h, Attr ID: 0) is calculated from Gear ratio (Class ID:
64h, Ins ID: 6091h) and Feed constant (Class ID: 64h, Ins ID: 6092h), as follows.
Position actual value (64h, 6064h, 0)
=
Position actual internal value (64h, 6063h, 0) × Feed constant (64h, 6092h)
Position encoder resolution (64h, 608Fh) × Gear ratio (64h, 6091h)
Each value in ( ) of the formula indicates Class ID, Ins ID, and Attr ID from the left.
When the unit is degree, the operation result will be limited within 0 to 359999.
