AC-Tech Error Codes
Fault
Description & Possible Causes
AF High Temperature Fault: Ambient temperature is too high; Cooling fan has failed (if
equipped).
CF Control Fault: A blank EPM , or an EPM with corrupted data has been installed. Performa
a factory reset using Parameter 48 - PROGRAM SELECTION.
cF Incompatibility Fault: An EPM with a different parameter version has been installed.
Either remove the EPM or perform a factory reset (Parameter 48) to change the
parameter version of the EPM to match the parameter version of the drive.
dF Dynamic Braking Fault: The drive has sensed that the dynamic braking resistors are
overheating and shuts down to protect the resistors.
EF External Fault: TB-13A and/or TB-13C is set as an External Fault input and TB-13A
and/or TB-13C is open with respect to TB-2. Refer to Parameter 10 and/or 12
GF Data Fault: User data and OEM defaults in the EPM are corrupted.
HF High DC Bus Voltage Fault: Line voltage is too high; Deceleration rate is too fast;
Overhauling load. For fast deceleration or overhauling loads, dynamic braking may be
required.
JF Serial Fault: The watchdog timer has timed out, indication that the serial link has been
lost.
LF Low DC Bus Voltage Fault: Line voltage is too low.
OF Output Transistor Fault: Phase to phase or phase to ground short circuit on the output;
Failed output transistor; Boost settings are too high; Acceleration rate is too fast.
PF Current Overload Fault: VFD is undersized for the application; Mechanical problem with
the driven equipment.
SF Single-phase Fault: Single-phase input power has been applied to a three-phase drive.
UF Start Fault: Start command was present when the drive was powered up. Must wait 2
seconds after power-up to apply Start command if START METHOD is set to NORMAL.
F1 EPM fault: The EPM is missing or damaged.
F2-F9, Fo Internal Faults: The control board has sensed a problem - consult factory.
