If an
absolute encoder
is used, it is possible to decide, after the control
voltage is switched off and on, whether the drive still is at the target
position of the last accepted positioning block (end position reached).
The "end position reached" message is generated as soon as the drive is
ready for operation again ("bb" contact closed).
If a
single-turn encoder
is used, the "end position reached" message is
not clearly defined after a voltage interrupt until the first target position has
been run to or homed.
Note:
The "end position reached" message is only retained if the
axis has not been moved during the interruption. If the axis is
moved into the positioning window during the interruption, the
"end position reached" message will also be generated! After
activating drive enable, positioning block acknowledge
changes as described under "Acknowledgment with drive
enable switched off".
Status Messages
In addition to the status messages during the "drive-internal interpolation"
mode, the "end position reached" status message is generated in the
"positioning block mode" (bit 4 = 1 in
P-0-4061, Positioning block status
word
), if the following applies:
•
|S-0-0430
– S-0-0051/S-0-0053| < S-0-0057 (In Position)
- and -
•
no sequential block has been selected.
See also "Status Messages" in section "Drive-Internal Interpolation"
See also Parameter Description "P-0-4061, Positioning block
status word"
The following parameters provide further diagnostic possibilities:
•
P-0-4051, Positioning block acknowledgment
→
acknowledgment of the currently accepted and active positioning
block
Note:
At "Drive Halt" the selected positioning block is returned in
negated form (complementary to positioning block mode).
•
P-0-4052, Positioning block, last accepted
→
contains the last accepted positioning block (stored in non-volatile
form)
Note:
For sequential block chains this is always the first block of the
sequential block chain!
•
P-0-4053, Positioning block, last active
→
contains the last active positioning block (stored in non-volatile
form)
