Parameter
bXZeroPos
BOOL
Status signal: "Cycle zero crossing in the modulo cycle of the master measuring sys-
tem"
FALSE Cycle zero crossing did not occur:
The resulting dnXActPos_p master position is non-zero, the resulting
master value is in the x modulo cycle.
TRUE Cycle zero crossing occurred:
•The bXZeroPos output is statically set to TRUE if the resulting
dnXActPos_p master position is zero.
•The bXZeroPos output is set to TRUE for one task cycle if the resul-
ting dnXActPos_p master position performs a step change to the
following x modulo cycle (dnXSpeedOut_s >0:x
max
 0) or to the
previous x modulo cycle (dnXSpeedOut_s <0:0 x
max
).
Parameter Possible settings Information
C05090 Coupling measuring systems X and Y
0 Coupling via feed constants
One of the units of the master
measuring system is mapped to one
of the units of the slave measuring
system (Lenze setting).
1 Coupling via cycles
One of the cycles of the master
measuring system is mapped to one
of the cycles of the slave measuring
system.
2 Free coupling
Synchronism depends on the ratio
between the gearbox factors of the
master drive/slave drive and on the
coupling factors, C05092/1 and
C05092/2.
