injury.
1336 PLUS Adjustable
Frequency AC Drive w/
Reference Guide
Overload Fault Excessive motor load exists. Reduce it
07 so output current does not exceed %
current set by the [Overload Current].
Overtemp Fault Check for blocked or dirty heat sink
08 fins. Ambient temperature must not
exceed 40
° C (104° F).
Overvolt Fault Monitor AC line for high line voltage or
05 transient conditions. Can also be
caused by motor regeneration. Extend
decel time or install dynamic brake.
Phase U, V, W Fault Check wiring between drive and motor.
38, 39, 40 Check motor for grounded phase.
P Jump Err Flt Reserved for future use.
37
Poles Calc Flt Calculated value of [Motor Poles] must
50 be between 2 and 32. Check program-
ming of [Motor NP RPM] & [Motor NP
Hertz].
Power Loss Fault Monitor the incoming AC line for low
03 voltage or line power interruption.
Power Mode Fault Check all connections to the Control
26 Board/Language Module.
Power Overload 2 Drive rating of 150% for 1 minute has
26 been exceeded. Reduce load.
Power Test Flt Internal power mode variable received
46 incorrect value. Check Power/Driver Bd.
Precharge Fault Check the precharge circuit.
19
Precharge Open Check the precharge circuit.
56
Reprogram Fault Occurs after drive has been reset to
48 factory default values. Clear fault or
cycle drive power. Reprogram.
ROM or RAM Flt Internal ROM/RAM tests failed. Check
68 Language Module.
Run Boost Fault [Run Boost] set greater than [Start
34 Boost]. Verify correct programming.
Serial Fault Check for break in communications
10 line.
Shear Pin Fault 2 Programmed [Current Limit] exceeded
63 & [Shear Pin Fault] enabled. Check load
requirements & {Current Limit] setting.
Temp Sense Open Heat sink thermistor open or malfunc-
55 tioning. Check thermistor/connections.
Undervolt Fault Monitor the incoming AC line for low
04 voltage or line power interruption.
UV/UW/VW Short Fault Check motor and external wiring to
41, 42, 43
drive output terminals for a short.
Xsistr Desat Flt One or more output transistors were
47 (Frame C & up only) operating in active region, instead of
saturation. Check for damaged transis-
tors.
Drive Fault Reset Power-up attempted with open Stop
22 contact or closed Start contact.
EE Init Read Trouble reading EEPROM during
53 initialization. Check Power/Driver Bd.
EE Init Value Stored parameter value out of range on
54 initialization. Check Power/Driver Bd.
EEprom Checksum EEPROM checksum does not match.
66 Check connections to Power/Driver Bd.
EEprom Fault EEPROM will not write a new value.
32 Check connections to Control Board.
FGND 10ms Over Occurs if 10ms interrupt is pending
52 before current interrupt is complete.
Ground Fault Check motor and external wiring to
13 drive output for a grounded condition.
Ground Warning If enabled, indicates lower ground current
57 level than Ground Fault (see above).
Hertz Err Fault No valid operating frequency. • Check
29 [Minimum/Maximum Freq] parameters
• Check [Skip Freq 1, 2, 3, Band] •
Check for loose connections or trans-
ducer loss at 4-20mA input, TB2.
Hertz Sel Fault Reprogram [Freq Select 1] and/or
30 [Freq Select 2] with a correct value.
Loop Overrn Flt Overrun of the 2.5ms control loop.
23 Check connections to the Driver Board.
Max Retries Fault Check buffer for fault requiring reset.
33 Correct cause & clear by pressing local
Stop key or cycling TB3 Stop input.
Motor Mode Flt Fault detected on Control Board. Check
24 connections to board/Language Module.
Motor Stall Fault If motor is drawing excessive current
06 (over 150%), motor load is excessive
and will not allow the drive to acceler-
ate to set speed. A longer accel time or
a reduced load may be required.
Neg Slope Fault Check programming. • [Maximum
35 Voltage] must be greater than [Base
Voltage]
1 • [Maximum Freq] must be
greater than [Base Frequency] 1 • [Base
Voltage] must be greater than [Start
Boost] • If [DC Boost Select] = “Full
Custom”, [Base Voltage] must be greater
than [Break Voltage] and [Break Voltage]
must be greater than [Start Boost].
Open Pot Fault Check external pot. circuit at TB2 for an
09 open circuit.
Op Error Fault • A SCANport™ device requests a read/
11 write of a data type not supported. •
[Motor Type] set to “Sync PM” & [Stop
Mode Used] set to “DC Brake” • [Motor
Type] set to “Sync Reluc” or “Sync PM”
& [Speed Control] set to “Slip Comp”.
Overcurrent Flt Check for short circuit at drive output
12 or excessive load conditions at motor.
