Synchronisation of absolute value encoder and profile
In the ideal case, the profile pulse and encoder pulse are identical. But more commonly the case
shown in the graphics occurs:
Y
0° 360°
X
720°
360° 0°
CDATA−OFFS−XIN
0
1
0
0
Profile pulse
1 Encoder pulse
In order to adapt the curve profile to the machine, the starting point of the profile can be shifted
towards the zero point of the encoder with the entry of code C1476/x. The profile can be shifted by
max. one profile pulse (+) compared to the encoder.
l Apply offset to the input CDATA−OFFS−XIN. The inputs CDATA−XOFFS and CDATA−XFACT
have no effect!
The pulse lengths of profile and encoder will not be changed!
)
Note!
The encoder pulse of single−turn absolute value encoders is 360°. This corresponds
to the number of increments of the encoder constant, e.g. 8192
increments/revolution. Then, the pulse recurs. The process can also be represented
as follows:
l 360° = 1 revolution
l 720° = 2 revolutions etc.
