Chapter overview
This chapter describes the winder and instructs how to use the winder blocks of the DCS550. All needed
parameters can be found in the groups 61 to 66.
Winder basics
Activate the winder by means of following steps:
1. choose a winder macro with WinderMacro (61.01),
2. activate the winder blocks by setting WiProgCmd (66.01) = Start,
3. the outputs of the winder blocks are activated and send references to the speed control chain using
WriteToSpdChain (61.02).
Winder blocks
The winder blocks are sorted according to their default execution sequence.
Speed reference scaling
The Line speed reference is converted to motor speed reference by the diameter
calculation. That means:
−
100 % line speed reference - see LineSpdScale (61.09) - correspond to 100 %
motor speed - see SpeedScaleAct (2.29) - at minimum diameter - see
DiameterMin (62.05).
M1SpeedScale (50.01) is set according to maximum needed motor speed and not to
rated motor speed.
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
max
, 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 used to saturate the speed controller and thus only active when WinderMacro
(61.01) = IndirectTens or DirectTens.
