8.4.4 Monitor Display of Reference Pulse Counter and Feedback Pulse Counter
The monitor display of reference pulse counter and feedback pulse counter is expressed in 32-bit hexadecimal.
When the control power supply is turned ON, reference pulse and feedback pulse will be “0.” The pulse
numbers will increase when the servomotor moves in the counting-up direction of the linear scale (phase-A
progression) and decrease when the servomotor moves in the counting-down direction of the linear scale
(phase-B progression).
Displays the pulse number from 0 to FFFFFFFF (4294967295) in sequence. If one pulse is decreased from 0,
the digital operator and the panel operator display FFFFFFFF (4294967295) and then decrease from this
pulse number. Also, if one pulse in increased from FFFFFFFF (4294967295), the digital operator and the
panel operator display 0 and increase from this pulse number.
When using the 8-bit serial converter unit, the feedback pulse will be 256 pulses/scale pitch.
