Condition
The Integrated Dynamic Brake (IDB) receives either the DIR_torqueActual Controller Area Network (CAN) signal as Signal Not Available (SNA) or the DIR_axleTorqueQF CAN signal as INVALID or FAULTED for longer than 100 milliseconds.
Clear Condition
Valid DIR_torqueActual and Valid DIR_axleTorqueQF are received for 100 milliseconds.
