Problem or Symptom
Converter thermal switch tripped.
The thermal model for the converter
indicates that the temperature has
exceeded its rating.
The thermal model for the converter
indicates that the temperature has
exceeded a user-programmable limit.
All three AC input phases are detected
as absent when an axis is enabled.
Some, but not all AC input phases are
detected as absent. The nn sub-code is
defined as follows:
01: L1 is missing.
02: L2 is missing.
03: L3 is missing.
The converter pre-charge circuit
detected that the DC bus did not reach
an appropriate voltage level after
charging for a period of time.
The thermal model for the shunt circuitry indicates that the temperature
has exceeded its rating.
The thermal model for the shunt circuitry indicates that the temperature
has exceeded a user-programmable limit.
The shunt module in a multi-axis
system has a fault.
With three-phase power present, the
DC bus voltage is below limits.
DC bus voltage fell below the
undervoltage limit while an axis on the
follower power rail was enabled.
The DC bus voltage is measured below a
user limit when the DC bus was
expected to be charged.
The DC bus voltage is measured above a
factory limit.
A blown fuse was detected in the power
structure.
