FAULT ACTIONS
e fault actions (eect of fault) in Table 23 use the action code bits individually or when combined as
listed in the fault action column in Table 24. e variable System_Action (0x4E00), which is available
in the CIT Programmer List View ( ), or TACT, returns the decimal number corresponding to the
active fault action bit(s). e example illustrates how to determine and plan for faults in both single
and dual motor applications.

Action Code
Description
Hex Bit(s)
NO_ACTION 0x00000000
ShutdownMotor 0x00000001 1 Disables the motor.
ShutdownMainContactor 0x00000002 2
Shut down the Main contactor.
Opens the main by de-energizing the main
contactor driver, only if Main Enable = On.
ShutdownEMBrake 0x00000004 3
Shut down the EM Brake.
Sets the EM Brake by de-energizing the driver, only
if the parameter Set EM Brake On Fault = On.
ShutdownThrottle 0x00000008 4 Set the Throttle_Command = 0%.
ShutdownInterlock 0x00000010 5 Set the Interlock_State = Off.
ShutdownDriver1 0x00000020 6 Shut Down Driver1 (e.g., turn off the driver’s PWM).
ShutdownDriver2 0x00000040 7 Shut Down Driver2 (e.g., turn off the driver’s PWM).
ShutdownDriver3 0x00000080 8 Shut Down Driver3 (e.g., turn off the driver’s PWM).
ShutdownDriver4 0x00000100 9 Shut Down Driver4 (e.g., turn off the driver’s PWM).
ShutdownPD 0x00000200 10 Shut down Proportional Driver (legacy name).
FullBrake 0x00000400 11 Set the Brake_Command = 100%.
ShutdownPump 0x00000800 12 Disables the pump.
TrimDisable 0x00001000 13 Disable Dual Drive trim calculation.
SevereDual 0x00002000 14
For a Dual Drive system, one controller has a severe
fault but the main contactor must stay closed so the
other controller can continue to operate.
ShutdownSteer 0x00004000 15 Steer angle = 0° (Dual Drive applicable).
LOSDual 0x00008000 16
For a Dual Drive system, it uses the max speed set
by the Dual_LOS_Max_Speed parameter.
ShutdownDriver5 0x00010000 17 Shut Down Driver 5 (e.g., turn off the driver’s PWM).
ShutdownDriver6 0x00020000 18
Shut Down Driver 6 (as applicable to the controller;
e.g., turn off the driver’s PWM).
ShutdownDriver7 0x00040000 19
Shut Down Driver 7 (as applicable to the controller;
e.g., turn off the driver’s PWM).
ShutdownCoilSupply 0x00080000 20
Shuts down (turns off) the Coil Supply (return)
voltage. (Note, based upon the controller model, this
will also shut down the low-side drivers).
ShutdownVehicle 0x01000C0F 25, 12, 11, 4, 3, 2, 1 Evokes all Fault Actions as per the indicated bits.
