Template:DCBLDCMotor SurgeCurrentLimit

Surge Current Limit is an advanced feature on new Phidget motor controllers. It allows you to safely exceed your Current Limit for a limited time (approximately one second, intelligently determined by your controller), allowing for faster acceleration from your motor than would otherwise be possible.

For applications where faster acceleration is desirable, we recommend setting your Surge Current Limit equal to the stall current of your motor. For all other applications, the Surge Current Limit can be set equal to the Current Limit, which will disable the feature.

Enabling Functionality

Surge Current Limit vs Current Limit	Surge Current Limit Functionality
Surge Current Limit > Current Limit	Enabled
Surge Current Limit = Current Limit	Disabled
Surge Current Limit < Current Limit	Disabled*

* The controller ensures that the Surge Current Limit is never set lower than the Current Limit. If an attempt is made to set the Surge Current Limit below the Current Limit, the controller will automatically adjust the Current Limit to match. Similarly, if the Current Limit is set higher than the Surge Current Limit, the controller will increase the Surge Current Limit to match.

Other Considerations

• Over Temperature conditions may reduce your Surge Current Limit.
