Check the type and location settings
of the modules (parameters
14.1/14.2, 15.1/15.2 or 16.1/16.2).
Configuration of module failed.00 0004
Check that the module is properly
seated in its slot.
Check that the module and the slot
connector is not damaged.
Try installing the module into
another slot.
Replace brake chopper if external.
Drives with internal choppers will need
to be returned to ABB.
