mode
Signal name, description PROFIBUS bitposn–setFct. No.
Control requested/no control possible – x x ZSW1.9
The status of the DP slave is signaled to the DP master using this output signal.
1 signal Control requested
The DP master is requested to accept control.
Recommendation:
As a result of this output signal, the DP master should accept control and control bit
STW1.10 ”Control requested/not control requested” should be set to ”1”.
Note: (from SW 4.1)
For a two–axis drive, this bit is only influenced at axes which also retrieve data from a
publisher via slave–to–slave communications
(refer to Chapter 5.10).
0 signal Control not possible
The DP master is signaled that control is not possible. This is, for example, the case for
the following states:
– the ”DP slave 611U” has still not irun–up
– the ”SimoCom U” tool has taken–over the master control
– the clock–cycle synchron. PROFIBUS no longer operates with clock cycle synchronism
– for slave–to–slave communications, not all of the links have been established to the
publisher (from SW 4.1)
Comparison value reached/comparison value not
reached
– x – ZSW1.10
The output signal indicates whether the comparison value, set using P1418:8, has been fallen below.
1 signal actual value > comparison value (P1418:8)
0 signal actual value < comparison value (P1418:8)

signal with inverted logic.
In n–set operation, this signal occupies the PROFIBUS bit ZSW1.10 if spindle positioning has not
been selected (from SW 5.1) (P0125=0). For the ”spindle positioning” function (from SW 5.1), the ”ref-
erence position reached/outside reference position” signal occupies ZSW1.10 (P0125=1), refer to
output signal Function No. 60.
