Fault Protection
The DC Trombone 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
