PARAMETERS
Position detected signal (Pr.1294 to Pr.1297, FP signal)
• The position detected signal (FP signal) is turned ON when the current position [before the electronic gear] exceeds the
position detection level (Pr.1295 10000 + Pr.1294). To use the FP signal, set "60 (positive logic) or 160 (negative logic)" in
any of Pr.190 to Pr.196 (output terminal function selection) to assign the function.
• Whether the position detection is determined on the plus side or minus side can be selected by Pr.1296 Position
detection selection. When "0" is set, the position is detected on both the plus and minus sides. When "1" is set, the
position is detected on the plus side only. When "2" is set, the position is detected on the minus side only.
• When a current position varies, the position detected signal may repeat ON/OFF (chatter). Setting hysteresis to the
detected position prevents chattering of the signal. Use Pr.1297 Position detection hysteresis width to set a hysteresis
width.
