Address Assignment
Bytes 5 to 7 Corresponding to the selected JOB:
• With JOB 1= actual value coordinates
• With JOB 3 = switch-off difference
• With JOB 4 = switchover difference
• With JOB 9 = reference point coordinates
• With JOB 10
– Byte 5: Bit 0 = latch at positive edge at DI2
– Byte 5: Bit 1 = latch at negative edge at DI2
• With JOB 11 = path difference for direction of rotation monitoring
• With JOB 15
– Byte 5: 0 = Residual distance
– Byte 5: 1 = Actual speed
– Byte 5: 2 = error information
