2.2.7. 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
2.2.8. Built-in Protection
• Additional heat-sink options, for demanding applications:
 External Heat Sink with fins (P/N with suffix 2)
 External Heat Sink with fins and fan (P/N with suffix 1)
