2.2.4. Communication Options
Depending on the application, Drum HV (High Voltage) users can select from two
communication options:
• RS-232 serial communication
• CAN for fast communication in a multi-axis distributed environment
2.2.5. Feedback Options

• Digital Halls – up to 2 kHz
• Incremental Encoder with Digital Halls for commutation – up to 20 Megacounts 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

• Elmo drives provide supply voltage for all the feedback options
2.2.6. Fault Protection
The Drum HV (High Voltage) 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
