If a fault occurs during the running of the AC drive and the handling of fault is set to "Continue
to run", the AC drive displays A** and continues to run at the frequency set in F9-54.
The setting of F9-55 is a percentage relative to the maximum frequency.

The signal of the motor temperature sensor needs to be connected to the optional I/O
extension card. AI3 on the extension card can be used for the temperature signal input.
The motor temperature sensor is connected to AI3 and PGND of the extension card. The
AI3 terminal of the MD380 supports both PT100 and PT1000. Set the sensor type correctly
during the use. You can view the motor temperature via U0-34.
If the motor temperature exceeds the value set in F9-57, the AC drive reports an alarm and
acts according to the selected fault protection action.
If the motor temperature exceeds the value set in F9-58, the DO terminal on the AC drive
allocated with function 39 (Motor overheat warning) becomes ON.

Upon instantaneous power failure or sudden voltage dip, the DC bus voltage of the AC drive
reduces. This function enables the AC drive to compensate the DC bus voltage reduction
with the load feedback energy by reducing the output frequency so as to keep the AC drive
running continuously.
• If F9-59 = 1, upon instantaneous power failure or sudden voltage dip, the AC drive
decelerates. Once the bus voltage resumes to normal, the AC drive accelerates to the
set frequency. If the bus voltage remains normal for the time exceeding the value set in
F9-61, it is considered that the bus voltage resumes to normal.
• If F9-59 = 2, upon instantaneous power failure or sudden voltage dip, the AC drive
decelerates to stop.
