Possible program sequence:
1. The following happens if the BERO/cam in block 9 signals a 0/1
edge at the digital input before the braking phase:
– The motor brakes along the braking ramp
– A block change with delete distance to go is initiated
– The measured position value is written into P0062 (measuring
position)
– The program continues with block 10. As a result of the cam
feedback signal via start byte bit 7, this immediately receives the
start condition, specified in the SM/MM start and changes to
block 11.
2. The following happens if the BERO/cam in block 9 did not provide a
signal at the digital input before the braking phase:
– The motor brakes along the braking ramp and then changes,
after this has been initiated, to traversing block 10
– If, the cam still outputs a signal in the braking phase, then the
measuring function in block 10 is executed and a change is
made to traversing block 11.
– If a cam does not output a signal in the braking phase, then traversing
block 10 does not have a valid start condition and therefore
goes into the state ”wait for start condition”.
In this case, the program has not been completed. When the cam
signal or BERO outputs a signal via the digital input, the program with
block 11 is continued without a position having been measured.
