Signal name
Output when the dancer roll position or the roll tension value goes lower
FDN
than the limit determined by the setting of Pr.132 PID lower limit.
Output when the dancer roll position or the roll tension value goes higher
FUP
than the limit determined by the setting of Pr.131 PID upper limit.
Output when the dancer roll position or the roll tension becomes
Y231
abnormal due to a break.
Y232 Output when the diameter calculation is completed at an operation start.
Output when the diameter reaches the setting in Pr.648 Target winding
diameter or longer for winding.
Y233
Output when the diameter reaches the setting in Pr.648 Target winding
diameter or shorter for unwinding.
Output when the winding/unwinding length is equal to or more than the
value of determined by the settings of Pr.1264 Winding length
Y234
detection (lower 4 digits) and Pr.1346 Winding length detection
(upper 4 digits).
Output while the dancer roll position or the roll tension is within a range
Y235 determined by the setting of Pr.423 Dancer / tension sensor feedback
detection level. This signal is also output when the inverter is at a stop.
Output when the commanded line speed reaches the target line speed
Y236
while the reel change function is valid.
Output while the commanded line speed increases. The signal can be
Y237 input to the terminal to which the Inertia compensation acceleration
(X111) signal of the inverter for the driving shaft is assigned.
Output while the commanded line speed decreases. The signal can be
Y238 input to the terminal to which the Inertia compensation deceleration
(X112) signal of the inverter for the driving shaft is assigned.
Output when the output current average value reaches or exceeds 50%
Y239 of the inverter rated current. (This function is only available for the SND
rating.)
