The standard ramp will be re-configured for the winder control.
Commissioning hints:
For proper calculation following rules apply:
−
Maximum motor speed (n
max
) is reached with minimum diameter (D
min
) at maximum line speed (v
max
).
−
The scaling of line speed and motor speed is needed, because the winder works with relative values (percent).
1. Set LineSpdUnit (61.12) to the desired unit.
2. Set LineSpdScale (61.09) to the maximum line speed. Thus, the maximum line speed corresponds to 20,000
internal line speed units.
3. Set LineSpdPosLim (61.10) to maximum line speed.
4. Calculate the maximum needed motor speed:

5. Set M1SpeedScale (50.01) = n

even if the motor data allow a wider speed range. Thus, the maximum motor
speed corresponds to 20,000 internal speed units.
6. Set M1SpeedMax (20.02) = n
max
+ max WindSpdOffset (61.14) in rpm, even if the motor data allow a wider speed
range.
7. Set M1SpeedMin (20.01) = - [n
max
+ max. WindSpdOffset (61.14) in rpm], even if the motor data allow a wider
speed range.
− WindSpdOffset (61.14) is only active when WinderMacro (61.01) = IndirectTens or DirectTens.
61.09 LineSpdScale (winder set, line speed scaling)
Line speed scaling.
LineSpdScale (61.09) defines the line speed that corresponds to 20,000 internal speed
units. The line speed scaling should be set in a way, that 20,000 internal speed units equal 100 % line speed.
The line speed unit is defined in
