5.3 Sequence I/O Signals
5.3.2 Output Signals
5-16
The NEAR signal is generally used in combination with the /INPOSITION (Positioning Comple-
tion Output) signal.
Note: You must allocate the /NEAR signal to use it. Use PnBCE = n.X (/NEAR (Near Output) Signal Allocation)
to allocate the signal to a connector pin. Refer to the following section for details.
5.3.4 Allocating Output Signals to Pins and Parameter Settings on page 5-20
 Setting the Position Near Width
You set the condition for outputting the /NEAR (Near Output) signal in PnB2F (Near Width). The
/NEAR signal is output when the difference between the target position and current position is
equal to or less than the setting of PnB2F.
Note: Normally, set PnB2F to a value that is larger than the setting of PnB2D (Positioning Completed Width).
/V-CMP (Speed Coincidence Detection Output) Signal
This signal is output when the Servomotor speed is the same as the reference speed.
Note: You must allocate the /V-CMP signal to use it. Use PnBCF = n.X (/V-CMP (Speed Coincidence Detec-
tion Output) Signal Allocation) to allocate the signal to a connector pin. Refer to the following section for
details.

/POSRDY (Homing Completed Output) Signal
This signal is output when the position information becomes valid after homing is completed.
Note: Use PnBD2 = n.X (/POSRDY (Homing Completed Output) Signal Allocation) to allocate the /POSRDY
signal to another connector pin. Refer to the following section for details.

Typ e Signal Pin 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.
