Digital input functions
The following table shows the operating behavior of the basic device depending on the signal at the digital input.
Signal at | Setting | Operating behavior |
|---|---|---|
Prioritized | – | The "Activation" signal activates the prioritized terminal control and deactivates the current control, e.g. via fieldbus. During activation, the control performs an error reset once. If no direction of rotation enable is selected via further digital inputs, the controller stops the drive with the set deceleration and inhibits the output stage (FCB01). |
Prioritized | Edge detection after STO and POWER ON | If the prioritized terminal control has been activated by a digital input signal, the controller enables the drive in positive direction of rotation via this signal (FCB04). If both directions of rotation are active, the controller inhibits the drive (FCB04). |
Edge detection after STO and POWER ON | If the prioritized terminal control has been activated by a digital input signal, the controller enables the drive in positive direction of rotation via a positive edge at this same digital input (FCB04). If both directions of rotation are active, the controller inhibits the drive (FCB04). | |
Prioritized | Edge detection after STO and POWER ON | If the prioritized terminal control has been activated by a digital input signal, the controller enables the drive in negative direction of rotation via this signal (FCB04). If both directions of rotation are active, the controller inhibits the drive (FCB04). |
Edge detection after STO and POWER ON | If the prioritized terminal control has been activated by a digital input signal, the controller enables the drive in negative direction of rotation via a positive edge at this same digital input (FCB04). If both directions of rotation are active, the controller inhibits the drive (FCB04). |
WARNING
Danger due to unexpected startup. If you deactivate the prioritized terminal control, the drive is immediately controlled by the original control source. Depending on the settings of the original control source, the drive may restart unexpectedly.
Severe or fatal injuries.
- Check the parameters and signals of the original control source before deactivating.
- Make sure that the settings of the parameters and signals of the original control source do not pose any risks.
