Displays the number of

Note: ELS modes only.
Note: This monitor is

and should be used
only to confirm that
encoder counts are
being received.

*1: Access Level (A1-01): Q = “Quick Start”, A = “Advanced”, F = “Factory”.
*2: Unit is dependent on the setting of the Position Units Selection (P1-10). When the position error is greater
than the maximum value that can be displayed, the digital operator will flash “OVER” in place of the U1-96 data.
When reading by network communication (register 726H), the unit is fixed at quadrature encoder counts.
