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
