The zc-smart-blind position is based on a calibrated run time for the installation, see How do I calibrate the zc-smart-blind?. The blind position can be controlled using the Dali arc level where the total run time is a linear representation of the installation. Contrary to the concept of a lighting control, a zc-smart-blind has to drive a physical motor and cannot have immediate response times. The zc-smart-blind will control the motor to achieve the requested arc level based on the calibrated run time.
Fading
The product will not represent fading while moving if no fade time is set. Where a Dali fade is set and running, the virtual arc will change in accordance with the requested fade, however the motor can only drive at its fixed rate. If the fade is faster than the rate of the motor, the virtual arc will change at the fade rate, but the actual blind position will change at a slower rate. Where the fade rate is slower than the rate of motion of the motor, the blind will run to its virtual arc and then pause until the next arc change.
Stop Fade
To stop the blind whilst it is moving, a Dali stop fade (dapc 255) can be sent to the product to stop the blind immediately. The arc level will then update to the actual position the motor was able to achieve in the time it ran. This stop fade command will be adhered to even if there is not a Dali fade running on the product.
