CSDP Plus Servo Drive User Manual

Position completion detection and in position detection
The user can set the timing for the position command completion at
the servo drive that received a position command from the controller,
and if the difference between the position of the load and the position
command is smaller than the set value, the signal for position
completion detection /P-COM can be displayed.
Set the decision range for displaying /P-COM
signal at SEt-18. The display range is 0 to 1000
pulse and the default value is 10.
If the user sets the timing of the position command proximity at the
servo drive that received the position command from the controller
and the difference between the load position and the position
command is smaller than the preset value, the in position detection
signal /NEAR can be displayed.
Set the decision range for displaying /NEAR signal
at SEt-22. The display range is 0 to 1000 pulse and
the default value is 20.
The motions required at the moment of position completion can be
shortened if /NEAR signal and /P-COM signal are used together, so that
the controller can confirm the in position signal before position
completion detection signal and prepare for the next sequence.
Setting these parameter does not affect the accuracy of the final
position decision.
ATTENTION
If the position completion range is large while the system is
operating at a low speed, /P-COM output signal can be kept
ON.
