# DC blinds with Encoder

Configure DC-powered blinds, slides, and awnings with encoder-based position feedback, including calibration parameters and current limits.

Last updated: 2026-10-08

Position of DC blinds.

## Service settings of blinds

### Normal operation current

All calibration parameters are the same as for AC blinds, except for one extra parameter:

| Attribute | **Default value** |
|------------------------|------------------------|
| Set reverse motor direction | Off |

### Encoder settings

Calculation of position and angle of blinds is based on counting impulses from encoder.

Encoder settings section consists of following attributes:

| Attribute | Default value |
|-----------|---------------|
| Max time to wait for encoder signals start in up direction | 150 ms |
| Max time to wait for encoder signals start in down direction | 150 ms |
| Number of impulses total | 2000 |
| Number of impulses for angle change<br>Not applicable for slides. | 103 |
| Calibration current<br>Limit of current during calibration. | 71% |
| Normal operation current up<br>Limit of current during normal operation up. | 83% |
| Normal operation current down<br>Limit of current during normal operation down. | 38% |
| Maximal current down change<br>Prevent reloading blind up in case when it is moving down. Stops blind moving down in case the current down is higher than average current down in defined percent. | 250% |
| Impulses per second to regulate speed.<br>Holds constant speed by using the number of impulses per second. If this is not possible to reach it holds higher possible or lower possible speed. To disable speed control set to 0. | 0 |
| Minimal PWM value.<br>Set minimal PWM value to regulate blind speed or to use soft start and soft end. | 50 |
