8.11 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.
8.12 Braking Characteristics
Function with or without control panel Parameter
Braking effect when varying the preset value ≤ 4 stages (br1) 207
Braking effect when varying the preset value ≥ 5 stages (br2) 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!
8.13 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
8.14 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.
8.15 Inputs for Proximity Switches
Function with or without control panel Parameter
Switch proximity switches for inputs in2, in7, in8, in9 (nAm) 295
If parameter 295 is set at “1“, a load resistor is connected in parallel to inputs in2, in7, in8, in9, which allows to operate
2 wire proximity switches.
