e fault actions (eect of fault) in Table 6 use the same bit-structure as the User_Fault_Action_xx
listed in the OEM-dened User Faults on page 113. e variable System_Action (available in WinVCL
Monitor or TACT) returns the decimal number corresponding to the active fault action bit(s). e
Dual Drive fault actions, Bits 12–15, are listed in the supplemental Dual Drive Operation manual.
System_Action Bit Action
No dened System_Action Effect of fault as noted in Table 6
Bit0 = ShutdownMotor Disable the motor.
Bit1 = ShutdownMainContactor Shut down the main contactor (only if Main Enable = On)
Bit2 = ShutdownEMBrake Shut down the EM brake (only if EM Brake Disable Upon Fault = On).
Bit3 = ShutdownThrottle Set the Throttle_Command = 0%.
Bit4 = ShutdownInterlock Set the Interlock_State = Off.
Bit5 = ShutdownDriverl Shut down Driver1.
Bit6 = ShutdownDriver2 Shut down Driver2.
Bit7 = ShutdownDriver3 Shut down Driver3.
Bit8 = ShutdownDriver4 Shut down Driver4.
Bit9 = ShutdownPD Shut down Proportional Driver
Bit10 = FullBrake Set the Brake_Command = 100%.
Bit11 = [reserved] N/A (for 1232–1238E/SE, and 1239E controllers)
Bit12 = TrimDisable Disable Dual Drive trim calculation.
Bit13 = SevereDual
For Dual Drive system, one controller has a severe fault but the main
contactor must stay closed so the other controller can continue to operate.
Bit14 = ShutdownSteer Steer angle = 0° (DD applicable).
Bit15 = LOSDual
For Dual Drive system, set the max speed to Dual_LOS_Max_Speed
parameter for operation in Limited Operating Strategy.
Example:
HPD/Sequencing Fault, Flash Code 47.
Effect of fault = Shutdown Throttle.
System_Action = 8 (equates to Bit3 set: 0000 0000 0000 1000)
