• Resolver
 Programmable 10 to 15 bit resolution
 Up to 512 revolutions per second (RPS)
 Encoder outputs, buffered, differential
• Tachometer and Potentiometer
 Two inputs for Tachometer Feedback:
• Up to ±50 VDC
• Up to ±20 VDC
 Potentiometer Feedback:
• 0 to 5 V voltage range
• Resistance: 100 Ω to 1000 Ω
• Elmo drives provide supply voltage for all the feedback options.
2.2.7. Fault Protection
The Bassoon 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
