3.4.5 Absolute value encoder
Purpose
The absolute actual position value should be known immediately after mains switching so that
homing is not necessary (for instance if homing is not possible because of machining or processing
circumstances).
l The following functions cannot be executed for positioning with absolute value encoder:
– Homing in program operation,
– manual homing
– Program function set position value" (PS mode C1311 = 5).
Tip!
Homing (to determine the machine zero) can be simulated when using touch probe positioning and
the home position setting function.
3.4.5.1 Absolute value encoder via encoder connection X8
Function
l Connection of sine/cosine absolute value encoders with hyperface communication interfaces
to encoder input X8. Absolute value encoders with a number of increments of 512 periods/rev
and the corresponding data format of the initialisation value of 2
14 inc/rev can be used (e. g.
Stegmann SCS70, SCS60).
l The following absolute value encoders can be used as of the device version 33.93xx.EP.2x.62:
