Control Functions
A virtual motor model is used to calculate the reached position of the floating actuator. To achieve an accurate positioning the motor model and the actuator must be synchronized. For this purpose there are 3 processes implemented:
- Over-travel which happens only in the end position. It does not influence the control circuitry. If the accuracy of the relay timing causes a drift in the actuators position, the control will operate towards the referring end positon were the over-travel synchronizes the control signal with the actuator position.
- Synchronization interrupts the control algorithm and moves the actuator to an end position. Based on your application this disturbs the control circuitry and in consequence it can cause damage to your system. (E.g. synchronization to open position in underfloor heating or in district heating systems or freezing in air handling units).
- “FeedbackPosition” input: The optional feedback signal from the actuator can be adapted and used as real position. In this case the actuator is kept synchronized even if a manual operation causes the deviation.
