Description
Recommended Action
1
M, R, I
F
Module Start
Failure
The module failed to start
because of an error with
one of the following: (1)
NVRAM (2) FPGA (Field
Programmable Gate Array)
(3) Configuration ID.
Power down and restart.
2
R, I
F
Desat
The fault may be caused by
one of the following: The
Inverter’s IGBT (Insulated
Gate Bipolar Transistor) is
faulty. The Inverter IGBT is
overloaded. The IGBT
driver’s PCB (Printed Circuit
Board) is faulty.
Power down and restart. If the
fault is not resolved contact
your ABB Service Agent to
have relevant module replaced.
3
R, I
F
Desat
Cooling Time
A reset was attempted too
soon.
Wait for 15 min before
pressing Reset.
4
M, R, I
AB
LVDC PSU
Voltage Low
One of the following
scenarios has occurred:
- The control power supply
has failed, or
- The auxiliary module is
faulty.
Check the AC supply voltage is
correct.
If the warning is not resolved,
contact your ABB Service
Agent to have the auxiliary
module replaced.
5
R, I
F
Interlock
Error
Two of the IGBTs (Insulated
Gate Bipolar Transistor)
from the same bridge are
activated.
Note: Only one should
activate at any one time.
Replace the faulty module.
6
M, R, I
F
SPI
Watchdog
Error
There is an SPI (Serial
Peripheral Interface Bus)
watchdog error.
Ensure all communication
cables are connected and not
damaged.
If damaged, contact your ABB
Service Agent to have the
cables replaced.
7
M, R, I
F
Combined
FPGA Fault
There is a generic FPGA
(Field-Programmable Gate
Array) fault.
Check all communication
cables.
8
R, I
F
DC Bus
Overvoltage
The DC Bus has risen to an
unsustainable voltage
because of one of the
following scenarios:
- The utility supply voltage
is too high
- There is excessive load
regeneration
Check the utility supply
voltage
Review the load types.
9
R,I
W
DC Bus
Voltage High
The DC Bus voltage is high.
There may be an earth fault
in the supply or excessive
load regeneration.
Wait until the DC voltage has
returned to normal.
If the warning is not resolved,
contact your ABB Service
Agent.
