Safety-related characteristic data for operation with non-safety-related rotary
encoder with mechanical fault exclusion
In accordance with EN 61800-5-2 : 2007, Table D.16 (Motion and position feedback
sensors), fault exclusions are permitted for faults in the mechanical connection between the
sensor (encoder) and motor.
Permitted encoder types and output signals
Permitted encoder types:
