The master drive output signal should be connected to the input
signal of the slave drive.
Exception:
If, for a double–axis module, P0891 (B) = 1, i.e. the position ac-
tual value of drive A is internally connected to the position refer-
ence value from drive B, then the following applies:
The ”request passive referencing” output signal from drive A
(master drive A) is internally and automatically recognized by
drive B (slave drive). In this case, external wiring is not required.
The permanent coupling can be switched–in via an input signal or
with the traversing block. Additional traversing blocks are not per-
mitted.
Example, switching–in with a traversing block using the ”Start–up
Tool SimoCom U”:
Command: COUPLING IN
Block change enable: End
If reference point approach is started at the master drive, and the
slave drive is coupled–out and coupled–in again, then the slave
drive outputs faults 131 and 605 if the master drive has reached its
reference point. This means that after a reference point approach
has been started, it is no longer possible to de–couple the axes.
The following parameters are used for the ”axis coupling” function:
P0179
Mode, passive referencing (from SW 5.1)
P0400
Ref. point coordinate, master drive (from SW 4.1)
P0401
Coupling factor, revolutions master drive
P0402
Coupling factor, revolutions slave drive
P0410
Configuration, coupling that can be switched–in
P0412
Synchronous offset position
P0413
Offset, synchronous velocity
P0420
Position difference, measuring probe to the zero
point, slave drive (from SW 3.5)
P0425:16
Coupling positions
P0898
Modulo range, master drive (from SW 3.5)
P0884
Position output value PROFIBUS – No. of increments
P0891
Source, external position reference value
P0895
External position reference value – No. of increments
P0896
Ext. position reference value – No. of dimension
system grids
P0897
Inversion, external position reference value
P0898
Modulo range, master drive
