1 μm (10
ence Unit Selection) to mm, and set fixed parame-
ter No. 09 (Number of Digits Below Decimal Point)
to 3.
Set the load travel distance per load shaft rotation
to a value from 1 to 2,147,483,647 (reference
*4, *5
units).
Set the value of m when the load shaft rotates n
*4, *5
times in response to m encoder shaft rotations to a
value from 1 to 65,535.
Set the value of n when the load shaft rotates n
*4, *5
times in response to m encoder shaft rotations to a
value from 1 to 65,535.
When an infinite-length axis is selected with fixed
parameter No. 7 (Axis Type Selection), set the posi-
tion at which to reset every rotation to a value from
*3
1 to 2,147,483,647.
Set the number of pulses per encoder rotation to a
value from 1 to 2,147,483,647 (pulses/rev).
Enable or disable disconnection detection for
phases A and B.
Set the phase-C pulse filter to a value from 0 to
65,535 (μs).
