EF4
External
Fault 4
External fault occurs on Terminal S4.
Alarm or fault defined by the External
Fault Selection table (table 5-80 on
page 5-96).
1. Check constant H01-04 for
proper programming.
2. Check the condition of the input
terminal S4.
X X
EF5
External
Fault 5
External fault occurs on Terminal S5.
Alarm or fault defined by the External
Fault Selection table (table 5-80 on
page 5-96).
1. Check constant H01-05 for
proper programming.
2. Check the condition of the input
terminal S5.
X X
EF6
External
Fault 6
External fault occurs on Terminal S6.
Alarm or fault defined by the External
Fault Selection table (table 5-80 on
page 5-96).
1. Check constant H01-06 for
proper programming.
2. Check the condition of the input
terminal S6.
X X
EF7
External
Fault 7
External fault occurs on Terminal S7.
Alarm or fault defined by the External
Fault Selection table (table 5-80 on
page 5-96).
1. Check constant H01-07 for
proper programming.
2. Check the condition of the input
terminal S7.
X X
EF8
External
Fault 8
External fault occurs on Terminal S8.
Alarm or fault defined by the External
Fault Selection table (table 5-80 on
page 5-96).
1. Check constant H01-08 for
proper programming.
2. Check the condition of the input
terminal S8.
X X
ERR
EEPROM
R/W Err
EEPROM Read/Write Fault.
EEPROM internal data did not match
when initializing the parameter.
1. Cycle Power.
2. User initialize (A01-05=1110).
3. Replace Control board. X
FAn
Internal Fan Fault. Internal cooling
fan has malfunctioned.
Alarm or fault defined by L08-32.
1. Cycle power to the drive.
2. Check for fan operation.
3. Verify the fan elapsed time with
U04-03 and verify the fan
maintenance timer with U04-04.
4. Replace fan.
X X
GF
Ground Fault
During operation, the inverter sums
the currents of all three motor
phases. Ideally, the sum should
always equal zero. If the sum is
greater than 50% of the inverter rated
output current, a GF occurs.
1. Disconnect motor from drive and
check it for shorts using a
megger.
2. Ensure that R/C Surge
Suppressors are used across all
brake contactor coils to prevent
disturbance by electrical
transients.
X
HBB or
HBBf
(flashing)
Hardware Base Block
External Base Block Indicator. The
flashing Hardware Base Block signal
is a result of either of the Safe
Disable inputs being open. The motor
will begin coasting when the
Hardware Base Block signal is open,
and the brake relay digital output will
close.
1. Check signal status at the input
terminals H1 and H2.
2. Check the Sink/Source Selection
for the digital inputs (see table 3-
7 on page 3-19).
3. If the Safe Disable function is not
utilized, verify that H1 and H2
jumpers are installed correctly
(see table 3-7 on page 3-19).
4. Replace either the control board
or the entire drive.
X
KLX
Klixon
Klixon Circuit Alarm. Input by MFDI
H01-0x = 56 or 57.
1. Check Motor for Overtemp.
2. Check Klixon Circuit. X
LC
Load Check Err
Load Check Fault. Load is greater
than specified amount.
Alarm or fault defined by C05-02.
1. Reduce Load.
2. Check Load Check sequence
set-up. (C05-xx).
