12.5.6 P945 Synchronous encoder counting direction (X14)
Setting range: NORMAL
/INVERTED
Defines the counting direction of the synchronous encoder. The setting must be made
so the counting direction of the motor encoder (X15) and the synchronous encoder
(X14) match.
12.5.7 P947 Hiperface offset X14
Setting range: –(2

This parameter is used to specify the zero point of the motor encoder display.
Use this parameter to define the machine zero without reference travel. It adds or sub-
tracts the offset from the encoder value.
• P905 Hiperface offset X15 (page 126) has an effect on the actual position of the
motor encoder H511.
H511 = Encoder value – P905
• P947 Hiperface offset X14 (page 136) affects the actual position of the external
encoder H510.
H510 = Encoder value – P947
The actual position is determined directly after the values have been entered. It does not
require prior reference travel.
Note:
When reference travel of a drive system takes place with a Hiperface
®
encoder, the
Hiperface
®
offsets (P905 or P947) are recalculated and overwritten due to the reference
travel depending on the set actual position source.
The following applies:
• P905 = Encoder value – P900
• P947 = Encoder value – P900
