Motorized Curtain Integration Issue

[Samimul_Islam]

Hello,

Hope all KNX expert are well and good.

One of our Client want to integrate Motorized Curtain and Roller blind with 8 channel actuator (MTN6705-0008) and touch switch (MTN6215-5910). In motorized curtain and Blind has 3 wire for communication (1 is open, 1 is close and 1 is common). we have assigned group address in both device but curtain and blind only open and close or up and down can't stop desire position. we have attached ETS program, Video and wiring for your more understanding.

Please note that the curtain and blind brand name is A-OK which is china.

Could you please support and valuable feedback to solve the issue?

Can you share the manual of the used blind motor?

I have seen multiple times devices (low voltage) like this that requires the up and down wire connection to the common at the same time to stop, this is not possible in blind actuator mode, if that is the case you need to use normal switch mode to be able to do that, but to determine if that is your problem i need to see the device manual..

In addition to Erwin’s comment

did you checked if the travel time set in the actuator parameters ismatching the driver actual travel time?

This is not really helpful, i don’t master Chinese so i can’t understand any of it..

You need to know how it’s controlled, i guess it has a wire to common for up, a wire to common for down and usually when up and down wire are both to common is stop, but i can’t tell you now as there is no clear understanding of the manual..
