V810/V820/V850 control panel display
 Arrow above symbol "position 1" on key 4 (V810) / on key 7 (V820/V850) is displayed corresponds to position 1
 Arrow above symbol "position 1" on key 4 (V810) / on key 7 (V820/V850) is displayed corresponds to position 1A
 Arrow above symbol "position 2" on key 4 (V810) / on key 7 (V820/V850) is displayed corresponds to position 2
 Arrow above symbol "position 2" on key 4 (V810) / on key 7 (V820/V850) is displayed corresponds to position 2A
If the V810, V820 or V850 control panel is connected, the positions will be displayed only on the control
panel!
6.11 Positioning shift
Function with or without control panel
Parameter
Positioning shift
(PSv)
269
Determine by means of parameter 269 whether the drive is to stop exactly on the position (parameter 269 = 0)
or some increments after the position.
6.12 Braking Characteristics
Function with or without control panel
Parameter
Braking effect when varying the preset value 4 stages
Braking effect when varying the preset value 5 stages
(br1)
(br2)
207
208
 Parameter 207 regulates the braking effect between speed stages
 Parameter 208 influences the braking effect for the stop
The following applies to all setting values: the higher the value, the stronger the braking reaction!
6.13 Braking Power at Standstill
Function with or without control panel
Parameter
Braking Power at Standstill
(brt)
153
This function prevents unintentional "wandering" of the needle at standstill.
The effect can be checked by turning the handwheel.
 The braking power is effective at standstill
- at stop in the seam
- after the seam end
 The effect can be set
 The higher the set value, the stronger the braking power
6.14 Starting Characteristics
Function with or without control panel
Parameter
Starting edge
(ALF)
220
The drive acceleration dynamics can be adapted to the sewing machine characteristic (light/heavy).
 High setting value = high acceleration
With a high starting edge setting and, in addition, possibly high braking parameter values on a light machine, the
characteristic may appear coarse. In this case, one should try to optimize the settings.
