Fault Protection

The Falcon includes built-in protection against possible fault conditions, including:

Software error handling

Status reporting for a large number of possible fault conditions

Protection against conditions such as excessive temperature, under/over voltage, loss of

commutation signal, short circuits between the motor power outputs and between each
output and power input/return

Recovery from loss of commutation signals and from communication errors
