Program end is output with a start signal if the actual number of pieces of the
last sentence in the last program run (cycle) has reached its nominal value. If
the number of pieces is not part of a nominal value sentence (storage location
2/1
≠
1 or 3) then the signal is output at the start of the last sentence in the last
program run.
All 3 signals remain also set in the interrupted (stop) state but not in the reset
state. Alternately, the signal output can also be performed with the
actual =
nominal signal (refer to storage location 2/11 in appendix A).
Stop is output if the Controller is in the interrupted or reset operating state. As
long as the drive is manually positioned or is in the automatic reference search
routine, the signal is reset for the appropriate unit.
Reset is only available if the »Sent.end« (1) or »BlockEnd« (2) variant has
been programmed on storage location 2/12. The signal is output if the
Controller is in the reset operating state. It is reset for the corresponding unit as
long as the drive is manually positioned or is in the automatic reference search
routine.
4.5.6 Range signals
These signals are axis-related. They occupy a certain BCD decade (4 bits) at a
data output module (A, L, or R) which has to be determined using storage
location 3/61 (refer to the Pin Layout in appendix B).
For each of the 4 ranges R1…R4, one start value and one end value must be
programmed (storage locations 3/63...70).
The signals can be assigned certain features regarding the interpretation of the
programmed values and the function of signals (storage location 3/62):
•
values for the start and end of the range are absolute positions
•
values for the start and end of the range are relative positions which are
related to the difference ‘nominal – actual’ (variance)
•
as before but signals are configured for controlling fast/slow-speed drives
The following distance and time diagrams show the relation as examples
whereas R
x refers to one of the R1 to R4 range signals and ‘start’ and ‘end’
characterize the values programmed for this.
