9.39 Handwheel Rotation by Keystroke

Function with or without control panel Parameter

Number of handwheel rotation steps (increments) triggered by keystroke (ihr) 260

Speed of handwheel rotation triggered by keystroke (nhr) 261

Delay time until the key is pressed down causing the handwheel to rotate continuously (ihP) 262

The handwheel can be set in motion by pressing a key. Select the input (in1…i10) used for this function and the direction

of rotation using parameters 240...249.

240...249 = 20 Direction of rotation corresponds to that of the machine.

240...249 = 21 Direction of rotation is opposite to that of the machine.

260 - Number of steps by which the handwheel rotates upon keystroke.

261 - Speed of handwheel rotation triggered by keystroke.

262 - Delay time until the key is pressed down causing the handwheel to rotate continuously

When the key is pressed briefly, i.e. no longer than the time set using parameter 262, the handwheel rotates by the steps set

using parameter 260.

When the key is held down, the handwheel rotates continuously until the key is released.

The handwheel rotates at the speed set using parameter 261.

9.40 Speed Limitation by means of External Potentiometer

Function with or without control panel Parameter

Speed limitation by means of external potentiometer (maximum value) (toP) 124

Speed limitation by means of external potentiometer (minimum value) (bot) 125

Function “speed limitation with external potentiometer” (Pot) 126

The functioning of the speed limitation when using an external potentiometer can be selected using parameter 126.

The desired limitation speed is set using a potentiometer connected to socket ST2/2-4. The maximum/minimum value of

speed limitation is set using parameters 124/125.

124: Maximum value for speed limitation with external potentiometer

125: Minimum value for speed limitation with external potentiometer

126 = 0 Function “external potentiometer” Off.

126 = 1 The external potentiometer is active whenever the pedal is pressed forward. The drive always runs with the set

speed limitation.

126 = 2 The external potentiometer is active only if an input is set at "25" by means of parameters 240...249. If the

selected input is enabled and the pedal pressed forward, the drive runs at limited speed. The speed limitation can

be enabled and disabled anywhere in the seam using the key.

126 = 3 Speed depending on high lift with potentiometer e.g. Juki (LU-2210/2260).

126 = 4 Speed depending on high lift with potentiometer e.g. Dürkopp Adler (767).

9.41 Signals A1 and A2

When using the V820 control panel, direct access by means of the function key (key 9) is possible!

Function with control panel Parameter

Signal A1 and/or A2 On/Off with slide-in strip 1...4 (-F-) 008 = 5

(left-hand arrow = A1, right-hand arrow = A2)

Function with control panel V820

Signal A1 On left-hand arrow above key On Key 8

Signal A2 On right-hand arrow above key On

Signals A1 and A2 On both arrows above key On

Signals A1 and A2 Off both arrows above key Off
