6. Output the direct measuring system via the angular incremental en-
coder interface
– Before SW 4.1 the following applies:
The direct measuring system signals cannot be output via the
angular incremental encoder interface.
If the angular incremental encoder interface is switched as out-
put (P0890 = 1), then the following is valid, independent of acti-
vating the direct measuring system (P0250 (A) = 0 or 1):
Interface
Output signals
Ang. incr. enc. interf. (A)
Signals of the motor meas. system
Ang. incr. enc. interf. (B)
No signals
– The following applies from SW 4.1:
The direct measuring system signals can be output via the angu-
lar incremental encoder interface. The angular incremental enco-
der interface as output becomes automatically active if P0890 is
set to 1 for the motor measuring system AND the direct measu-
ring system is activated (P0250 = 1). However, parameters
P0892 and P0893 are not effective for the angular incremental
encoder interface (B).

7. Direction adaptation for direct measuring systems
– P0231
Position act. value inversion
– P0232
Position ref. value inversion
8. You can toggle between the indirect measuring system (IM) and the
direct measuring system (DM) by changing P0250 and executing a
POWER–ON RESET.
– The parameters for the closed–loop position control are only
available once and must also be appropriately adapted,
e.g.:
P0231
Position act. value inversion
P0332
Position ref. value inversion
P0201
Backlash compensation
– The parameters for the gearbox and spindle pitch are only avail-
able once and must be set for the indirect measuring system,
e.g.:
P0236
Spindle pitch
P0237:8
Encoder revolutions
P0238:8
Load revolutions
– The adjustment status for absolute value encoders is changed
after changeover, i.e. P0175 is set to 0. A re–adjustment is re-
quired.
9. Which measuring system does the drive control use?
––> refer to P1792 (active measuring system)
