1336S-C003-AN-EN Allen Bradley
3 HP , Serial 1336
The 1336 PLUSAC drive provides a PWM adjustable frequency and voltage output for exceptional control of motor speed and torque. The output can be tuned to provide optimum performance under a wide variety of load conditions.
Name fault+Fault# : Undervolt Fault #04
Description : DC Bus voltage fell below the minimum value (388V DC at 460V AC input). [Line Loss Fault] and [Low Bus Fault] set to “enabled.”
Action : Monitor the incoming AC line for low voltage or line power interruption.
Name fault+Fault# : Overvolt Fault #05
Description : DC bus voltage exceeded maximum value.
Action : Monitor the AC line for high line voltage or transient conditions. Bus overvoltage can also be caused by motor regeneration. Extend the decel time or install dynamic brake option.
Name fault+Fault# : Motor Stall Fault #06
Description : Current remained over [Current Limit] setting (parameter 36) for more than 4 seconds.
Action : If the motor is drawing excessive current (over [Current Limit] setting), 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.
Name fault+Fault# : Overload Fault #07
Description : Internal electronic overload trip.
Action : An excessive motor load exists. It must be reduced such that drive output current does not exceed the current set by the [Overload Amps] parameter.
Name fault+Fault# : Overtemp Fault #08
Description : Heat sink temperature exceeds a predefined value of 90° C (195° F).
Action : Check for blocked or dirty heat sink fins. Check that the ambient temperature has not exceeded 40° C (104° F). Check fan
Name fault+Fault# : Overcurrent Flt #12
Description : Overcurrent is detected in instantaneous overcurrent trip circuit.
Action : Check for a short circuit at the drive output or excessive load conditions at the motor.
Name fault+Fault# : Ground Fault #13
Description : A current path to earth ground in excess of 100A has been detected at one or more of the drive output terminals. NOTE: If ground current exceeds 220% of drive rated current, “Overcurrent Flt” may occur instead of Ground Fault.
Action : Check the motor and external wiring to the drive output terminals for a grounded condition.
Name fault+Fault# : Motor Thermistor #15
Description : An analog option board with thermistor input is installed and the value at the terminals is less than 60 ohms or greater than 3300 ohms.
Action : 1. Verify that thermistor is connected.
2. Motor is overheated. Reduce load.
3. Thermistor is not present. Remove option board.
Name fault+Fault# : Precharge Fault #19
Description : The precharge device was open 20ms after the end of a line loss condition or the bus charging alarm remains on for 20 seconds (precharge did not complete).
Action : See Chapter 1 for frame definitions.
1. Frames A1, A2, A3 - Check the precharge circuit. Replace the drive.
2. Frame B - Check the precharge circuit. Replace the Power Driver Bd. or complete drive as required.
3. All larger frames - Check the precharge circuit. Replace the input SCRs, SCR Firing Board, Power Driver Board or complete drive as needed.
Name fault+Fault# : Load Loss Flt #20
Description : [Load Loss Detect] is set to “Enabled” and the drive output torque current was below [Load Loss Level] for a time period greater than [Load Loss time].
Action : 1. Verify connections between motor and load.
2. Verify level and time requirements or disable [Load Loss Detect].
Name fault+Fault# : EEprom Fault #32
Description : EEPROM is being programmed and will not write a new value.
Action : Check all wire and cable connections to the Main Control Board. Replace Main Control Board or complete drive as required.
Name fault+Fault# : Input Phase Flt #49
Description : The DC bus ripple has exceeded the value in [Phase Loss Level].
Action : 1. If the drive is operated on singlephase, the load derating level has been exceeded.
2. Check incoming power for a missing phase/blown fuse
Name fault+Fault# : Blwn Fuse Flt #58
Description : If the difference between the commanded voltage and the measured voltage is greater than 1/8 of rated voltage for 0.5 seconds, then a fault will be issued indicating that the bus fuse in 30 kW (40HP) & up drives has blown.
Action : Locate cause, replace fuse.
Name fault+Fault# : Power Overload #64
Description : The drive rating of 150% for 1 minute has been exceeded.
Action : Reduce load.
Name fault+Fault# : EEprom Checksum #66
Description : The checksum read from the EEPROM does not match the checksum calculated from the EEPROM data.
Action : 1. Reset to factory defaults & cycle input power.
2. Check all wire and cable connections to the Power Driver Board. Replace Power Driver Board or complete drive as required.
