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
 Absolute Encoder
 Interpolated Analog (Sine/Cosine) Encoder – up to 250 kHz (analog signal)
 Internal Interpolation – programmable up to x4096
 Automatic Correction of:
• amplitude mismatch
• phase mismatch
• signals offset
 Encoder outputs, buffered, differential.
 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 Cello 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
