This structure contains the parameters and feedback data to simulate the feedback signal for the control loop.
The simulation monitors the movement of the bobbin and the feeder, as detected by the unwinder. According to the movement, the amount of the foil inside the dancer is calculated. Based on this foil length, the position of the dancer is calculated and transferred to the unwinder as a feedback signal.
If the mechanic does not have a dancer, then the dancer movement can be interpreted as the stretching of the foil.

Description |
|---|---|---|
|
i_lrRadius |
LREAL |
The radius of the simulated bobbin. |
|
i_lrStartFillLevel |
LREAL |
The position of the dancer when starting the simulation in percentage of the whole dancer movement area. |
|
iq_xCauseDisturbance |
BOOL |
A positive edge adds i_lrDisturbanceValue to the position of the simulated dancer. This variable is set back to FALSE during the same program cycle. |
|
i_lrDisturbanceValue |
LREAL |
The value of which the dancer should be manipulated if iq_xCauseDisturbance is set in percentage of the whole dancer movement area. |
|
i_xUseDirectMaster |
BOOL |
TRUE: Instead of the internal monitored master movement the input i_ifDirectMaster is used for the simulation. This can be used, for example, if the master of the unwinder is the continuous moving machine master and the direct master is connected to the indexed moving foil feeder. |
|
i_ifDirectMaster |
SystemConfigurationItf. IF_IdentificationMandatory |
If i_xUseDirectMaster is set to TRUE, then a logical encoder which is connected to the foil feeding master has to be specified at this input. |
