P07 – [Last Fault] Fault Code Number
➀
➀
See Table 6.A below for fault descriptions.
Controllers equipped with a program keypad
module will flash the display when a fault is
present. If a fault occurs, parameter 07 – [Last
Fault] displays. You can cross reference the
number that appears on the display (e.g., 04) with
the fault numbers listed in Table 6.A.
Fault LED – (Without Program Keypad
Module)
Controllers without a program keypad module
come equipped with a fault LED. When the fault
LED illuminates, a fault condition exists.
Tips To Clear a Fault
Important: If a fault occurs, it is important to
address and correct the fault as well as the
condition that caused the fault.
To clear a fault, perform one of the following:
D Press the program keypad’s stop button.
D Cycle power to the controller.
D Cycle the input signal at TB3-8 to the
controller
.
D Set P54 – [Clear Fault] parameter to a “1”.

03 Power Loss
Fault
DC Bus voltage remains below 85% nominal on
power up for longer than 5 seconds.
Monitor incoming AC line for low voltage or line
power interruption.
04 Under Voltage
Fault
DC Bus voltage fell below the minimum. For
controllers rated at input voltage 200 – 240V AC,
undervoltage trip occurs at 210V DC bus voltage
(equivalent to 150V AC incoming line voltage).
For controllers rated at input voltage
380 – 460V AC, undervoltage trip occurs at
390V DC bus voltage (equivalent to 275V AC
incoming line voltage).
Monitor incoming AC line for low voltage or line
power interruption.
05 Over Voltage
Fault
DC Bus maximum voltage exceeded. For
controllers rated at input voltage 200 – 240V AC,
overvoltage trip occurs at 410V DC bus voltage
(equivalent to 290V AC incoming line voltage).
For controllers rated at input voltage
380 – 460V AC, overvoltage trip occurs at
815V DC bus voltage (equivalent to 575V AC
incoming line voltage).
Bus overvoltage caused by motor regeneration.
Monitor incoming AC line for excessive voltage.
Extend the decel time or install dynamic brake
module or external capacitor module. See
Appendix A.
