 In-position width (Pr.426, Y36 signal)
• The Y36 signal is used as the In-position signal.
• If the number of droop pulses (after electronic gear) reaches the Pr.426 setting value or smaller, the In-position (Y36) signal
turns ON. (The number of droop pulses (after electronic gear) is calculated by subtracting the current position (after
electronic gear) from the position command (after electronic gear).)
• To use the Y36 signal, set "36 (positive logic)" or "136 (negative logic)" in any parameter from Pr.190 to Pr.196 (Output
terminal function selection) to assign the function.
 Excessive level error (Pr.427)
• If the number of droop pulses (after electronic gear) reaches the Pr.427 setting value or smaller, E.OD (Excessive position
fault) is activated and the inverter output is shutoff. (The number of droop pulses (after electronic gear) is calculated by
subtracting the current position (after electronic gear) from the position command (after electronic gear).) Increase the error
threshold level when a small value is set as the Pr.422 Position control gain setting value. Set a small value for early
detection even when the load is heavy.
• If Pr.427 = "9999", E.OD is not activated regardless of the amount of droop pulses.
 During position command operation signal (PBSY signal)
• The During position command operation (PBSY) signal turns ON during position command operation. To use the PBSY
signal, set "61 (positive logic)" or "161 (negative logic)" in any parameter from Pr.190 to Pr.196 (Output terminal function
selection) to assign the function.
