172
External block change for coupling not possible
Cause
If there is an existing coupling, traversing blocks with external block
enable are only permitted if P0110 = 2.
Remedy
Correct traversing program
Change P0110 (configuration, external block change)
Acknowledgement RESET FAULT MEMORY

STOP IV
173
Coupling and traverse to endstop simultaneously
Cause
Not possible to simultaneously couple and traverse to the endstop.
Remedy
Correct traversing program
Acknowledgement RESET FAULT MEMORY

STOP V
174
Passive referencing not possible
Cause
For the passive referencing, the encoder interface must be switched as
input and the ”Positioning” mode must be set.
Remedy
– Set the ”Positioning” mode (P0700)
– Set angular encoder interface (P0890, P0891)

175
Passive referencing not realized. Supplementary info:
\%u
Cause
While the master drive corrects the zero mark offset, the slave drive
must pass over a zero mark.
Supplementary information
0 = Reference cam not found
1 = Reference cam not left
2 = Zero reference pulse not found
Remedy
Ensure that the cam of the slave drive is located between the cam and
the reference point of the master drive. Appropriately shift the cam
and/or increase the reference point offset (P0162) at the master drive.
If the zero pulse is not found, the reference point offset (P0162) must
also be increased at the master drive.

Absolute encoder must be adjusted
Cause
Passive referencing with absolute encoders (e.g. EnDat encoders) is
only possible after the encoder has been adjusted.
Remedy
Adjust the drive by setting the absolute value.
