6.6 Position Settling Signal
Position Settling Signal (OUT_COIN)
The position settling signal is used for notifying the PLC whether or not the motor is in the
proximity of the command position.
This signal is turned ON when (position command value - current position value) is within the
settling width set by the parameter (see the figure below). The settling width should be set
according to the required accuracy of the device. If the position deviation is small or the
settling width is set large, this signal may be turned ON even while the motor is operating.
Moreover, chattering may occur when the motor is close to stopping. If chattering occurs, it is
possible to set #29 [Cycle count for coin signal activation] so that the settling signal is not
turned ON until after the motor position settles.
The applicable coin window parameter varies with the setup status of input contacts
IN_POSW.0 to IN_POSW.2 while not in a table data operation.
In table data operation, it is possible to select which position settling width parameter to apply
for each table data.
