1336 TROUBLESHOOTING GUIDE FAULT CODES: Up to 37 fault codes may be displayed for the 1336. In each instance, a Fault may be reset by cycling power to the drive, or if Parameter 39 is set to 1, by pressing the Stop pushbutton. Resetting a Fault will not correct the problem. Corrective action must be taken prior to resetting the fault. 2-Position Mode Display Area The two character PR display is not used as part of the fault code display. However, it may be used to indicate the loss of enable. 3-Position Fault Code Display Area Freq PR F01 The three character Freq display is used to indicate the fault code acronym. The fault acronym will be displayed until a drive reset is initiated. Special Display- Enable Fault Freq PR __ __ ___ The enable interlock is open. The enable interlock is: Jumper 7-8 of J9 on the Main Control Board if interface option L1, L2, L3 is not installed. Terminal 30 of TB3 if interface option L1, L2, L3 is installed. Freq Special Test- Input Reset PR __ F01 This is not a fault but a code that is displayed each time the drive is powered up or when a fault is cleared. It indicates that drive logic is being reset to initial conditions. Freq Auxiliary Fault PR __ F02 The auxiliary input interlock is open. The auxiliary interlock is: Jumper 9-10 of J9 on the Main Control Board if interface option L1, L2, L3 is not installed. Terminal 28 of TB3 if interface option L1, L2 L3 is installed. Freq Power Loss PR __ F03 Occurs only if Parameter 40 is set to 0 and input power is interrupted for 0.2 seconds. Monitor the incoming AC line for low voltage or line power interruption. Freq Bus Undervoltage PR -- -- F04 Occurs when the DC bus drops below: 388V DC for drives with Base Driver/Power Supply Board Firmware Versions 1.11, 1.13, 1.14 or 3.01. 456V DC for drives with Base Driver/Power Supply Board Firmware Versions 1.01. Monitor the incoming AC line for low voltage or line power interruptions. Bus Overvoltage Freq PR __ F05 Occurs when the DC bus rises above: 810V DC for drive ratings B003-B200. 975V DC for drive ratings C003-C200. May be caused by high line voltage or excessive regeneration from the motor. Monitor the AC line for high line voltage or transient conditions. If caused by motor regeneration, extended decel time or dynamic braking may be required. Motor Stalled Freq PR __ F06 Indicates that the drive has not been able to change output frequency for: 4 seconds for drives with Base Driver/Power Supply Board Firmware Versions 1.11, 1.13, 1.14 or 2.01. 10 seconds for drives with Base Driver/Power Supply Board Firmware Versions 1.01. Conditions sensed are: Excessive Current : The motor is drawing excessive current (over 150%). The motor load is excessive and will not allow the drive to accelerate to set speed. A longer accel time or a reduced load may be required. Bus Voltage Rise The bus voltage has risen to 110% of nominal bus voltage. This indicates a regeneration condition that will not let the drive decelerate to a lower frequency. A longer decel time or dynamic braking may be required. Motor Overload Freq PR _ _ F07 The drive output current has exceeded the % of current set by Overload Current Parameter 38 for some period of time.
