100249 PLCopen MC_Home (with timestamp)
Description
NOTE
The block can only be used with a PLCopen application. For information on the
Homing function, see the description of the PLCopen applications (e.g.,
electronic cam, publication no. 441777).
When a positive edge is determined on the input
Execute , the block sends the
command MC_Home to position control. The value specified on Position is set
as the reference position and written to I34 .
When the input UseBrake contains the signal 1:active , the brake is applied after
the motion job is finished.
An identifier for the job can be entered on the input
StepID . The value is copied
to I193 . This ID can be used to follow the sequence in I193 when several
PLCopen blocks are being sequence-controlled.
The value must be connected to
ExeTStmp before the timestamp of the
Execute signal can be evaluated.
The command has been executed successfully when the output
Done is
1:active . Status 1:active on the output Aborted means that the command was
aborted by another command, for example. Status 1:active on the output Error
shows that positioning control found an error. The error code as per parameter
I90 can be read from the output ErrorID . When the output Active is 1:active , the
block sends the motion job to position control or the command is executed.
