[Feed (Obj. 6092h: 01h)] is automatically set in accordance with [Pr. PT01.2 Unit for position data]. Do not write a value to
[Feed (Obj. 6092h: 01h)]. Doing so will cause an error.
[Shaft revolutions (Obj. 6092h: 02h)] is automatically set. Do not write a value to [Shaft revolutions (Obj. 6092h: 02h)]. Doing
so will cause an error.
The values of [Feed constant (Obj. 6092h)] are as follows.
[Position actual value (Obj. 6064h)] is calculated from [Gear ratio (Obj. 6091h)] and [Feed constant (Obj. 6092h)] as follows.
If the unit is set to "degree", the result can be any value from 0 to 359999.
A value is automatically set in [SI unit position (Obj. 60A8h)] in accordance with the setting of [Pr. PT01.2 Unit for position
data].
The values of [SI unit position] are as follows.
