15EPM Chip — The drive uses a electronic programmingmodule (EPM) chip to store the program parameters. This is anEEPROM memory chip and is accessible from the front of theVFD. It should not be removed with power applied to theVFD.Loss of CCN Communications — Carrier ComfortNetwork® (CCN) communications with external controlsystems can be affected by high frequency electrical noisegenerated by the Motormaster® V control. Ensure unit is wellgrounded to eliminate ground currents along communicationlines.If communications are lost only while Motormaster V con-trol is in operation, order a signal isolator (CEAS420876-2)and power supplies (CEAS221045-01, 2 required) for the CCNcommunication line.Table 6 — Fault CodesThe drive is programmed to automatically restart after a fault and will attempt to restart three timesafter a fault (the drive will not restart after CF, cF, GF, F1, F2-F9, or Fo faults). If all three restart attemptsare unsuccessful, the drive will trip into FAULT LOCKOUT (LC), which requires a manual reset.LEGENDCODE DESCRIPTION RESETMETHOD PROBABLE CAUSE CORRECTIVE ACTIONAF High Temperature Fault Automatic Ambient temperature is too high;Cooling fan has failed (if equipped).Check cooling fan operation.CF Control Fault Manual A blank EPM, or an EPM with cor-rupted data has been installed.Perform a factory reset using Parameter48 – PROGRAM SELECTION. See DriveProgramming section.cF Incompatibility Fault Manual An EPM with an incompatible param-eter version has been installed.Either remove the EPM or perform a fac-tory reset (Parameter 48) to change theparameter version of the EPM to matchthe parameter version of the drive.F1 EPM Fault Manual The EPM is missing or damaged. Install EPM or replace with new EPM.F2—F9FoInternal Faults Manual The control board has sensed aproblemConsult factory.GF Data Fault Manual User data and Carrier defaults in theEPM are corrupted.Restore factory defaults by toggling P48 toanother mode. Then set P48 to desiredmode to restore all defaults for that mode.See Drive Programming section. If thatdoes not work, replace EPM.HF High DC Bus Voltage Fault Automatic Line voltage is too high; Decelerationrate is too fast; Overhauling load.Check line voltage — set P01appropriately.JF Serial Fault Automatic The watchdog timer has timed out,indicating that the serial link has beenlost.Check serial connection (computer).Check settings for P15.Check settings in communication softwareto match P15.LF Low DC Bus Voltage Fault Automatic Line voltage is too low. Check line voltage — set P01appropriately.OF Output Transistor Fault Automatic Phase to phase or phase to groundshort circuit on the output; Failed out-put transistor; Boost settings are toohigh; Acceleration rate is too fast.Reduce boost or increase accelerationvalues. If unsuccessful, replace drive.PF Current Overload Fault Automatic VFD is undersized for the application;Mechanical problem with the drivenequipment.Check line voltage – set P01 appropri-ately.Check for dirty coils.Check for motor bearing failure.SF Single-phase Fault Automatic Single-phase input power has beenapplied to a three-phase drive.Check input power phasing.Drive displays‘---’ eventhough driveshould berunningStart Contact is Not Closed Automatic Start contact is missing or notfunctioning.Check fan relay.VFD flashes“---”and LCSStart Contact is Not Closed Automatic Start contact not closed. Check FR for closed contact.VFD flashes57 (or 47)and LCSSpeed Signal Lost Automatic Speed signal lost. Drive will operateat 57 (or 47) Hz until reset or loss ofstart command. Resetting requirescycling start command (or power).Transducer signal lost. Check VDC signalbetween TB5 and TB2. Should be in rangeof 0.5V to 4.5V. 5VDC output should bepresent between TB6 and TB2.EPM — Electronic Programming ModuleFR — Fan RelayLCS — Loss of Control SignalTB — Terminal BlockVFD — Variable Frequency Drive
