The “B” Group of functions and parameters adjust some of the more subtle but useful aspects of motor control and system configuration.
Automatic Restart ModeThe restart mode determines how the inverter will resume operation after a fault causes a trip event. The four options provide advantages for various situations. Frequency matching allows the inverter to read the motor speed by virtue of its residual magnetic flux and restart the output at the corresponding frequency. The inverter can attempt a restart a certain number of times depending on the particular trip event:
•
•
•
When the inverter reaches the maximum number of restarts (3 or 16), you must power- cycle the inverter to reset its operation.
