The two measurements of voltage made by the controller have diverged
unexpectedly. The controller cannot operate.
Bus voltage is over the allowable limit. The controller is likely to have gone
into forced voltage control to bring this condition under control. The
controller is in danger of severe damage if this condition persists.
The motor is spinning faster than the allowable limit. Motoring is
significantly limited, and the motor may be generating to try to slow itself
down. If the over speed persists and is fast enough, the motor is in danger of
damage.
Bus current is over the allowable limit. The controller imposes limitations on
its output during this condition.
The motor's phase currents are exceeding limits. The controller is limiting
torque.
The measured currents in the three motor phases should equal zero at any
particular moment in time. If they do not, measurements are suspect, and
the controller imposes limitations on its output during this condition. (Note
that on average, the currents in the legs can be large, but sum to 0.)
The controller has detected a problem on one or more of the three motor
phases (A, B, or C) and assumes one or more IGBT switches are bad for the
controller module in question. The controller imposes limitations on its
output.
In high speed operation, the controller's phase adjustment has reached its
allowable limit. The controller imposes limitations on its output during this
condition.
The inverter/controller has detected a disconnected temperature sensor. The
controller imposes limitations on its output during this condition.
The temperature measurement is over the allowable limit. The temperature
limits are given on the "About UqmMotor" dialog box. The controller
imposes limitations on its output during this condition.
There are no position sensor inputs detected. Ensure that the position signal
cable is connected properly. The controller cannot operate.
The controller has detected a condition that often indicates that the rotor or
the position-sensing equipment has moved. The controller imposes
limitations on its output.
The position signal is bad. The controller cannot operate and must be reset.
Ensure that the position cable is properly connected.
