2.2.7 Fault Protection
The Guitar 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
