Reference point coordinate:
Range:
– 1 000 000 000
m to
+ 1 000 000 000
m
Incremental encoder and initiator:
Using the “Retrigger Reference Point” function switch and a synchronization event specified by the “Type
of Reference Point Retriggering”, the reference point coordinate is assigned to this event.
Absolute encoder (SSI)
An axis with an absolute encoder is always synchronized provided no error is detected (after transfer of the
first error-free SSI frame).
Read the description of absolute encoder adjustment in Section 8.4 (Page 8-12), explaining the
interaction of absolute encoder adjustment with other data.
Linear axis
The value of the reference point coordinate must be within the working range (including the start
software limit switch and end software limit switch).
Rotary axis
The value of the reference point coordinate must be greater than or equal to 0 and must be less than the
value “end of rotary axis” “ (0
≤
reference point coordinate < “end of rotary axis”).

Type of reference point retriggering:
Ranges:
0 = Ref. point switch and zero marker dir
1 = Ref. point switch and zero marker direction –
6 = Only ref. point switch
7 = Only zero marker
With “type of reference point retriggering”, you specify the conditions for synchronizing the axis when
working with an incremental encoder or an initiator (see also Section 9.8, Page 9-19)
