5.6.4Record selection: Carrying out a record
A record can be started in the Drive enabled" state.
This function is usually used for:
moving to any position from positions in the record
list,
processing a positioning profile by linking records,
known target positions that seldom change (formulation
change).
Sequence
1. Set the desired record number
in the output data of the
master. Until the start, the controller replies with the
number of the record last processed.
2. With a rising edge at START (CPOS.B1
) the controller
accepts the record number and starts the positioning job.
3. The controller signals with the rising edge at
Acknowledge start" that the PLC output data
has been
accepted and the positioning job is now active. The
positioning command will be processed irrespective of
whether CPOS.B1 START has
been reset to zero or not.
4. When the record is concluded, SPOS.B2 MC is set.
Causes of errors
 Homing has not been carried out.
The target p
osition is unreachable.
 Invalid record number.
