6 Description of the Functions
6.3 Axis couplings (from SW 3.3)
6-450
S
Rotary axis with modulo correction and basic coupling
The following applies for SW 3.3:
The coupling mode for rotary axes with modulo correction is not per-
missible for the master and slave drive.
The following applies from:
The coupling mode is permissible for rotary axes with modulo
correction.
S
Direct measuring system and axis coupling
For a drive with direct measuring system, the actual values of the
motor measuring system are always output via the angular incre-
mental encoder interface switched as output.
This means that an actual value coupling cannot be realized using
the direct measuring system.
S
The following applies for P0410 = 5 or 6 (from SW 3.5):
– It is only possible to precisely determine the position using the
fast input I0.x.
––> refer under the index entry "Input signal, digital – flying mea-
surement/length measurement"
– The standstill time of the slave drive up to the next workpiece
must be at least 1 IPO clock cycle (P1010).
– After COUPLING OUT for the slave drive, the drive should re-
tract to its waiting position as otherwise it will continue to be posi-
tioned away from the target position.
S
The following secondary conditions have to be taken into consider-
ation when parameterizing P0891:
– The following applies for P0891 = 1:
––> only exists for drive B;
––> for drive A, P0891 must be 0
– The following applies for P0891 = 2 or 3:
––> Selectable for drive A or B
––> The other drive is then the master drive where P0891
must be set to 0.
––> Coupling via the input signal "Activate coupling via
I0.x" (fast input) is not possible
S
If a setpoint source is selected, which is not available for the drive,
e.g. there is no optional PROFIBUS–DP module, then Fault 788 is
output.
