2.3.6. 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
