6–3 Troubleshooting
Name & Fault # Action Description
Ground Fault
13 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. Check the motor and external
wiring to the drive output terminals
for a grounded condition.
Ground Warning
57 A current path to earth ground
in excess of 2A has been
detected at one or more of the
drive output terminals. See
[Ground Warning]. Check the motor and external
wiring to the drive output terminals
for a grounded condition.
Hertz Err Fault
29 This fault indicates that there
is not a valid operating
frequency. It can be caused by
any of the following:
1. [Maximum Freq] is less
than [Minimum Freq].
2. Skip frequencies and skip
bandwidth eliminate all
operating frequencies.
3. 4-20mA input signal speed
reference has been lost and
[4-20mA Loss Sel] is set for
“Stop-Fault.”
1. Check [Minimum Freq] and
[Maximum Freq] parameters.
2. Check [Skip Freq 1], [Skip Freq
2], [Skip Freq 3] and [Skip Freq
Band] parameters.
3. Check for broken wires, loose
connections or transducer loss
at 4-20mA input, TB2.
Hertz Sel Fault
30 A frequency select parameter
has been programmed with an
out of range value. Reprogram [Freq Select 1] and/or
[Freq Select 2] with a correct
value. If problem persists, replace
Main Control Board or complete
drive.
HIM –> Drive Error 1 – The checksum read
from the EEPROM does not
match the checksum
calculated from the EEPROM
data.
Error 2 – Number of parame-
ters in saved profile does not
equal master.
Error 3 – Download was at-
tempted to a different type
drive (i.e. 1336–>1305).
Error 4 – Saved data not cor-
rect for new drive.
Error 5 – Drive is running while
attempting download. Retry download. Replace HIM.
Retry download. Replace HIM.
Download can only take place
with same type drive.
Capabilities of drive different then
master drive. Reprogram param.
Stop drive, then perform down-
load.
Loop Overrn Flt
23 An overrun of the 2.5ms
control loop has occurred. Check all connections to the
Power/Driver Board. Replace the
board or complete drive as
needed.
Max Retries Fault
33 Drive unsuccessfully
attempted to reset a fault and
resume running for the
programmed number of
[Reset/Run Tries]. Check fault buffer for fault code
requiring reset. Correct the cause
of the fault and manually clear by
pressing the local Stop key or
cycling the TB3 Stop input.
Motor Mode Flt
24 A fault has been detected
originating from the Control
Board. Check all connections to the
Control Board. Replace the board,
Language Module or complete
drive as required.
