loss
A79B BC short circuit
Cause
0006 Encoder type incompatible
with interface module type.
0007 Adapter not configured.
0008 Speed feedback configuration
has changed.
0009 No encoders configured to
encoder module
000A Non-existing emulation input.
000B Echo not supported by
selected input (for example,
resolver or absolute encoder).
000C Emulation in continuous mode
not supported.
Encoder feedback not used as
actual feedback, or measured
motor feedback lost (and
parameter 90.45/90.55
Warning).

Short circuit in brake chopper
IGBT
What to do
Check module type
against encoder type
Check module location
Use parameter
refresh to validate any changes in the
settings.
Configure the encoder in group
Encoder 1 configuration
configuration.
Check input selection
Check input selection
interface module type, and encoder type.
Check input selection
and serial link mode
settings.
Check that the encoder is selected as
feedback source in parameter
90.51.
is set to
Check that the encoder interface module
is properly seated in its slot.
Check that the encoder interface module
or slot connectors are not damaged. To
pinpoint the problem, try installing the
module into a different slot.
If the module is installed on an FEA-03
extension adapter, check the fiber optic
connections.
Check the auxiliary code (format XXXX
YYYY). "YYYY" indicates the problem
(see actions for each code below).

Replace brake chopper if external. Drives
with internal choppers will need to be
returned to ABB.
Ensure brake resistor is connected and
not damaged.
