P FW: Fin Width
 This parameter sets the notice mode of the output IPOS (In-position).
◊ Refer to “7.2.6. In-position: IPOS” for details.
 For the output IPOS, there are three notice modes set by the parameter FW (Fin width).
1) CFIN mode
After starting a positioning operation, the output IPOS opens for a time set by
the parameter FW at earliest. After completion of a positioning, the Driver Unit
holds the signal for completion of a positioning.
2) IPOS mode
After completion of a positioning, the System outputs the completion signal
depending on the state of position error.
3) FIN mode
After completion of a positioning, the System outputs the pulsing completion
signal. The time width of the completion signal is specified by the parameter
FW.

P GP: Gain Switching Point
 The parameter sets the threshold of position error for the automatic gain switching function.
◊ Refer to “8.5.4. Automatic Gain Switching” for details.
 It switches the gain for Motor stationary level when the position error is less or equal to the
setting of parameter GP for a time set by the parameter GT (Switching gain timer).
