2.2.5. Communication Options
Depending on the application, DC Whistle users can select from two communication options:
• RS-232 serial communication
• CANopen for fast communication in a multi-axis distributed environment
2.2.6. Feedback Options
• Incremental Encoder – up to 20 Mega-Counts (5 Mega-Pulse) per second
• Digital Halls – up to 2 kHz
• Incremental Encoder with Digital Halls for commutation – up to 20 Mega-Counts per
second for encoder
• Interpolated Analog (Sine/Cosine) Encoder – up to 250 kHz (analog signal)
 Internal Interpolation - up to x4096
 Automatic Correction of amplitude mismatch, phase mismatch, signals offset
 Auxiliary emulated, unbuffered, single-ended, encoder output
• Resolver
 Programmable 10 to 15 bit resolution
 Up to 512 Revolution Per Second (RPS)
 Auxiliary emulated, unbuffered, single-ended, encoder output
• Tachometer, Potentiometer
• Elmo drives provide supply voltage for all the feedback options
2.2.7. Fault Protection
The DC Whistle 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
