Control of asynchronous motors for blinds and awnings, C-OR-0008M

To control the 230 VAC motors with reverse switching of power supply coil (similarly to the 3-position drives for valves and dampers), we recommend to use relay outputs that can block simultaneous switching of both outputs (which usually causes damage to the motor drive).

Notes:

1. Relay outputs with interlocking switching of both outputs; after switching DO1, the motor goes up, when DO2 is switched, the motor goes down; if both outputs are switched on by mistake, the motor remains inactive.

2. The relay contacts have an inrush current of up to 80 A, so they have no problem managing the switching phenomena during switchning and opening contacts.

3. Considering the power of motors for shading elements actuation, the 1.5 mm² cross section of the power and control cables is sufficient.
