Signal name, description
External block change (from SW 3.1)
For a traversing block with the block change enable CONTINUE EXTERNAL, a flying block change can
be initiated using this input signal (refer to Chapter 6.2.10).
0/1 edge or
1/0 edge The external block change is initiated
When the edge is detected, in addition to the block change, the position actual value of
the axis is written into P0026 (position actual value, block change).
The behavior when the signal edge is missing can be set using P0110 (configuration, ex-
ternal block change).
Note:
If the braking distance of the new block is too high due to a lower velocity override, then the block change
enable is changed from CONTINUE FLYING to CONTINUE WITH STOP.
The "external block change" function can be initiated as follows:
S
Using input terminal I0.x or, for a direct measuring system, via I0.B (P0672)
– Recommended if P0110 p 1, as it is a fast input
– If the "external block change" function was parameterized at input terminal I0.x, then other termi-
nals with this function, or the "external block change" PROFIBUS control signal, no longer have
any effect.
– The external block change is detected depending on the direction.
The following applies:
Traversing in a positive direction ––> the 1/0 edge is identified as external block change
Traversing in the negative direction ––> the 0/1 edge is identified as external block change
The actual value can be inverted using P1011.0, P0231 and P0232.
There is no inversion, if none or 2 of these parameters are set to invert
––> increasing (decreasing) position actual value corresponds to a positive (negative) direction
The value is inverted, if one or all 3 parameters are set to invert.
––> increasing (decreasing) position actual value corresponds to a negative (positive) direction
– The value in P0026 corresponds to the existing position when the block change is detected.
S
Using input terminal I1.x to I3.x or I4 to I11
– Recommended, if P0110 q 2
– The external block change is independent of the direction.
– The value in P0026 does not precisely correspond to the block change position due to internal
signal propagation times.
S
Using the PROFIBUS control signal STW1.13
– The external block change is independent of the direction.
– The value in P0026 does not precisely correspond to the block change position due to internal
signal propagation times.
S
Refer under the index entry "Block change enable – CONTINUE EXTERNAL".
Note:
If P0110 q 2, then input terminal I0.x or I0.B may not be used as input, as, for these, the block change
can be initiated from different signal edges.
