5.3.3. Critical board ratings

In the Application Settings Device configuration -> Maximum ratings


Controller critical parameters settings window

Critical board ratings - This group is responsible for the maximum values of input current Max current (power) and voltage Max voltage (power) on the controller, the maximum current Max current (usb) and voltage Max voltage ( usb) for USB, the minimum voltage Min voltage (usb) for USB, and the board temperature Temperature (if the temperature is measured on the given controller version).

If the controller current consumption value, power supply voltage or the temperature goes out of the allowed range defined here then the controller turns off all power outputs and switches to Alarm state. At the same time the Alarm state information will appear in the main window (window background will change to red) and the out of range parameter value will be displayed in blue or red (below or above the limit respectively).

If the Low voltage protection flag is checked the low voltage supply protection is active. Then Low voltage off and below values of input voltage turns the controller into Alarm state.

The group Misc includes all other critical parameters settings.

Switch off power driver on overheat (> 125 ° C) - this parameter enables the Alarm state in case of power driver overheat.

Switch off power driver on H bridge alert - this parameter enables the Alarm state in case of the power driver malfunction signal.

Enter Alarm state when edge misset is detected - this parameter enables the Alarm state in case of incorrect boundary detection (activation of right limit switch upon moving to the left, or vice versa).

Sticky Alarm flags - locking of Alarm condition. If the Sticky Alarm flags check-box is unchecked the controller removes the Alarm flag as soon as it its cause is removed (e.g. in case of over-current the windings are disconnected, which results in the decreased current). If the Sticky Alarm flags is enabled, the Alarm mode cause and the Alarm mode are canceled by the Stop command only.

Reconnect USB on link break - if this option is enabled, then the controller will reset USB link if the connection breaks.
