6.20.4 Jumper S1
The jumper S1 located at the top right of the printed circuit board next to the 37-contact socket has the following function:
Jumper closed if no external potentiometer is connected.
Jumper open (factory setting) if an external potentiometer is connected.
6.20.5 Setting the Speed Limitation Depending on High Lift with the V820 Control Panel
Determine maximum speed (n2) using parameter 111.
Determine minimum speed (n10) using parameter 117.
Call parameter 188.
Press key E.
Press key F2.
Set high lift for walking foot (potentiometer on the machine) to the level up to which full speed is to be maintained
(upper break point).
New value of AB is taken over to XX.
Set high lift for walking foot (potentiometer on the machine) to the level from which minimum speed is to be effective
(lower break point).
New value of AB is taken over to YY.
Press the P key once Actual parameter is displayed. / Press the P key twice Exit programming.
6.20.6 Setting the Speed Limitation Depending on High Lift with the V810 Control Panel
Call parameter 188.
Press key E.
Press key F2. Actual display.
Press key F2. Previous values are displayed.
Press key F2.
Set new value (level) with potentiometer on the machine.
Press key F2.
Press key E. New value 08 (upper break point)
is entered.
Press key F2.
