Meaning
Current counter value or position value
The last acquired Capture value
Current measured value or complete SSI frame
Bits 3 to 7: Reserve; set to 0
Bit 2: Error when loading via control interface
Bit 1: Faulty encoder signal or SSI frame
Bit 0: Supply voltage L+ too low
Bits 6 to 7: Reserve; set to 0
Bit 5: Software gate status (with incremental encoder or pulse encoder)
Bit 4: Technology module started up and configured
Bit 3: Load request for Slot 1 detected and carried out (toggling)
Bit 2: Load request for Slot 0 detected and carried out (toggling)
Bit 1: Reset of event bits active

Bit 7: Count pulse or position value change detected in previous
measurement interval
Bit 6: Capture event has occurred
Bit 5: Synchronization has occurred (with incremental encoder or pulse
encoder)
Bit 4: Comparison event for DQ1 has occurred
