Troubleshooting

8–3

EEprom Checksum
66

The checksum read from the
EEPROM does not match the
checksum calculated from the
EEPROM data.

1. Reset to factory defaults (refer to

page A–12) & cycle input power.

2. Check all wire and cable connec-

tions to the Power Driver Board.
Replace Power Driver Board or
complete drive as required.

EEprom Fault
32

EEPROM is being programmed
and will not write a new value.

Check all wire and cable connections
to the Main Control Board. Replace
Main Control Board or complete drive
as required.

Encoder Loss
(Not Available)
60

The drive has detected an error in
the encoder signals. The error
could be due to a:
1. Loss of 1 or more channels.
2. Loss of quadrature.
3. Loss of differential signal (A &

A NOT or B & B NOT were high
at the same time).

Check encoder and wiring.

Fgnd 10ms Over
52

Microprocessor loop fault. Occurs
if a 10ms interrupt is pending
before the current interrupt is
complete.

Replace Main Control Board or com-
plete drive as required.

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 135 to
290% (depends on drive) 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.

Hardware Trap
18

Refer to the “Description” and “Action” statements for C167 Watchdog
(F17) on page 8–2.

Hertz Err Fault
29

This fault indicates that there is
not a valid operating frequency. It
can be caused by any of the fol-
lowing:
1. [Maximum Freq] is less than

[Minimum Freq].

2. Skip frequencies and skip

bandwidth eliminate all operat-
ing frequencies.

3. Analog input signal speed

reference has been lost. See
[Anlg Signal Loss] and
[4-20mA Loss Sel].

1. Check [Minimum Freq] and [Maxi-

mum Freq] parameters.

2. Check [Skip Freq 1], [Skip Freq 2],

[Skip Freq 3] and [Skip Freq Band]
parameters.

3. Check for broken wires, loose con-

nections or transducer loss at
analog inputs.

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 Con-
trol Board or complete drive.

HIM -> Drive

Refer to Table 8.B.

IGBT Temperature

Heatsink temperature exceeds
75

°

C (167

°

F).

Check for blocked or dirty heat sink
fins. Check that the ambient tempera-
ture has not exceeded 50

°

C (122

°

F).

Check fan.
