5.8 Braking Characteristics
Functions Parameter
Braking effect when varying the preset value ≤ 4 stages (br1) 207
Braking effect when varying the preset value ≥ 5 stages (br2) 208
Machine selection: 0 = normal, 1 = medium duty, 2 = heavy duty, (rEG) 225
3 = models 4180 and 4280
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!
5.9 Braking Power at Standstill
Functions 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
It does not work after power On,
5.10 Starting Characteristics
Functions Parameter
Accelerating power of the drive (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.
5.11 Actual Speed Display
Functions Parameter
Actual speed display (nIS) 139
If parameter 139 = ON, the V810/820 display shows the following information:
During operation:
The actual speed
Example: 2350 revolutions per minute
At stop in the seam:
The stop indication
At standstill after trimming:
On the V810, indication of the type of control
On the V820, indication of the set maximum speed
and the type of control
Example: 3300 revolutions per minute and type of control DA320G
