Positioning Near Signal - YASKAWA E-V Series User Manual

5.4.6 Positioning Near Signal

The host controller receives the positioning near signal prior to confirming the positioning-completed signal,
and performs the following operating sequence after positioning has been completed to shorten the time
required for operation.
This signal is generally used in combination with the positioning completed output signal.

• Set the number of error pulses in reference units (the number of input pulses defined using the electronic
gear.)
• The positioning near (/NEAR) signal is output when the difference (error) between the number of reference
pulses output by the host controller and the travel distance of the servomotor is less than the value set in this
parameter.
Note: Normally, the setting should be larger than that for the positioning completed width (Pn522).
