Signal status, description
If bit 7 = 0, then find reference mark request applies:
Bit Meaning
0 Function 1 Reference mark 1
1 Function 2 Reference mark 2
2 Function 3 Reference mark 3
3 Function 4 Reference mark 4
If bit 7 = 1, then find flying measurement request applies:
0 Function 1 Probe 1 rising edge
1 Function 2 Probe 1 falling edge
2 Function 3 Probe 2 rising edge
3 Function 4 Probe 2 falling edge
Note:
Request function
Bit x = 1
•
Do not request function
Bit x = 0
The following applies if more than one function is activated:
•
The values for all functions cannot be read until each activated function
has terminated and this has been confirmed in the corresponding status
bit (ZSW.0/.1/.2/.3 "0" signal again).
Reference mark search
•
It is possible to search for a reference mark.
External zero mark
•
Flying measurement
•
Positive and negative edges can be simultaneously selected.
Bit 6, 5, 4 Meaning
000 No function
001 Activate selected function
010 Read generated value
011 Cancel function
(x: Function selected using bit 0 to 3)
1 Not permitted
0 Reference mark search (fine resolution via p0418)
-
1 Request cyclic transfer of the absolute actual position value in
Gn_XIST2.
Used for (e.g.):
Additional measuring system monitoring
•
Synchronization during ramp-up
•
0 No request
1 Request parking encoder (handshake with Gn_ZSW bit 14)
