roll speed is 140[rpm] and the gear ratio is 11:1, the motor rotating speed is 1540[rpm]. In this case, if the set value
of WEB_54 Quick Stop of such two inverters is 5[sec], it stops after 5[sec] although the rotating speed of two motors
are not same where the multi-function input terminal (DIO_01 ~ DIO_07) set to “Quick Stop” is On.

7.7.12 WEB Jog Setting
1) WEB_55 JogSpd Web : Jog Speed Setting
2) WEB_56 JogTime Sel : Jog Acceleration/Deceleration Time Setting Select
3) WEB_57 JogAcc Time : Jog “Acceleration Time Setting
4) WEB_58 JogDec Time : Jog Deceleration Time Setting
If the multi-function input (DIO_01 ~ DIO_07) set to “Jog Web” is On, Process PID controller operates, but
doesn’t conduct diameter computation. In this case the set value of WEB_55 JogSpd Web is calculated in % of
WEB_08 MaxMotor SPD, deciding the motor rotating speed. For example, if the set value of WEB_08 MaxMotor
SPD is 300[rpm] and the jog speed set to WEB_55 JogSpd Web is 20[%] where the multi-function input (DIO_01 ~
DIO_07) set to “Jog Web” becomes O, the motor rotating speed is 60[rpm]. In case of jog operation, the jog can
set the Acceleration/Deceleration Time instead of the basic Acceleration/Deceleration Time (FUN_40 Acc Time-1,
FUN_41 Dec Time-1). When WEB_56 JogTime Sel is set to “No”, the basic Acceleration/Deceleration Time is applied
during jog operation mode, while when set to “Yes”, WEB_57 JogAcc Time and WEB_58 JogDec Time are applied
during jog operation mode.

7.7.13 Splicing Level Setting
In the splicing system, the winder core should be replaced without any change in line speed command. When splicing,
the process PID controller doesn’t operate in the empty core. Therefore, the multi-function input terminal (DIO_01 ~
DIO_07) set to “TensionDisable” should be On. The splicing function doesn’t operate during jog operation. In case the
web is wound in new core in the winder, sudden load change occurs. Such sudden change in load makes the speed
slower, which causes low tension of web, and finally the web becomes drooped. To avoid such phenomenon, you may
operate it at higher speed than the line speed command in splicing state. WEB_59 Splice Level is the [%] value for the
line speed command. For example, if the line speed command is 50[m/m], and the set value of WEB_59 Splice Level
