P214
Encoder direction.
="0": positive direction for encoder rotating clockwise.
="1": positive direction for encoder rotating anti-clockwise.
Setting aid:
♦
Switch off external position adjustment (P144=4) and data record
P214=0.
♦
Note S42 (position of external sensor).
♦
Proceed with POSR x axis.
♦
S1 and S42 must change by the same value (x).
• If the prefix of the modification is different, set data record P214="1".
•
If the modification has a different amount, check P143 and P98.

The command "SPEED SYNC" cannot be used in external position
localization!
A number overrun is possible in special applications. To prevent this occurring, the
following condition must be met:

Both parameters are set to 100% as standard. The time constants are then
identical and the filter ineffective. Meaning:

P67 < P68 or
P67 = 0

at high dynamic requirements.
Conditions: high-resolution measuring
system and low interference on the measuring
