Override response
The MC_MoveJog task can be aborted by
the following motion control tasks:
•
MC_Home Mode = 3
•
MC_Halt
•
MC_MoveAbsolute
•
MC_MoveRelative
•
MC_MoveVelocity
•
MC_MoveJog
The new MC_MoveJog task aborts the
following active motion control tasks:
•
MC_Home Mode = 3
•

Executes a series of individual
motions for a motor control axis
that can combine into a
movement sequence.
Individual motions are configured
in a technology object command
table for pulse train output
(TO_CommandTable_PTO).
