Application Functions
6-13
Setting the Output Timing of the /COIN (Positioning Com-
pletion Output) Signal
You can add a reference input condition to the output conditions for the /COIN signal to
change the signal output timing.
If the position deviation is always low and a narrow positioning completed width is used,
change the setting of Pn207 = n.X (/COIN (Positioning Completion Output) Signal Output
Timing) to change output timing for the /COIN signal.
6.1.9 /NEAR (Near) Signal
The /NEAR (Near) signal indicates when positioning completion is being approached.
The host controller receives the NEAR signal before it receives the /COIN (Positioning Comple-
tion) signal, it can start preparations for the operating sequence to use after positioning has
been completed. This allows you to reduce the time required for operation when positioning is
completed.
The NEAR signal is generally used in combination with the /COIN signal.
Note: You must allocate the /NEAR signal to use it. Use Pn510 = n.X (/NEAR (Near) Signal Allocation) to allo-
cate the signal to a connector pin. Refer to the following section for details.

Parameter Description
When
Enabled
Classification
Pn207
n.0
(default setting)
Output the /COIN signal when the absolute value of
the position deviation is the same or less than the
setting of Pn522 (Positioning Completed Width).
After
restart
Setup
n. 1

Output the /COIN signal when the absolute value of
the position deviation is the same or less than the
setting of Pn522 (Positioning Completed Width) and
the reference after the position reference filter is 0.
n. 2
Output the /COIN signal when the absolute value of
the position deviation is the same or less than the
setting of Pn522 (Positioning Completed Width) and
the reference input is 0.
Typ e Signal Connector Pin No. Signal Status Meaning
Output /NEAR Must be allocated.
ON (closed)
The Servomotor has reached a point
near to positioning completion.
OFF (open)
The Servomotor has not reached a
point near to positioning completion.
