Template:DCMotor Failsafe

Your controller will enter a Failsafe state in the following circumstances:

• The Failsafe timer has elapsed. For more information, view our Failsafe Guide
• The E-Stop circuit has been opened

When your controller enters a Failsafe state it will apply the Failsafe Settings listed below and reject all communication until the software channel has been closed and reopened.

Failsafe Settings

There are two Failsafe settings that can be customized for your application:

• Failsafe Braking Enabled
• Failsafe Current Limit

Failsafe Braking Enabled

Disabled (Default Behavior)

When disabled (default behavior), your controller will not attempt to slow down your motor upon entering a Failsafe state, it will allow it to coast (freewheel) instead.

Enabled

When enabled, your controller will forcefully slow down your motor upon entering a Failsafe state, which will often cause power to flow back to your supply (i.e. regenerative braking).

Failsafe Current Limit

This will supersede the Current Limit and Surge Current Limit when the controller has entered a Failsafe state.

Other Considerations

The Failsafe timer mentioned above can be enabled or disabled through an API. The E-Stop circuit is always enabled and cannot be disabled. If you do not intend to use it, you must leave the inputs shorted.
