Description
0 or 1 The MC_Home task cannot be aborted by any other motion control task. The new MC_Home task does not
abort any active motion control tasks. Position-related motion tasks are resumed after homing according to
the new homing position (value at the Position input parameter).
2 The MC_Home task can be aborted by the following motion control tasks:
MC_Home task Mode = 2, 3: The new MC_Home task aborts the following active motion control task.
MC_Home task Mode = 2: Position-related motion tasks are resumed after homing according to the new
homing position (value at the Position input parameter).
3 The MC_Home 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_Home task aborts the following active
motion control tasks:
• MC_Home Mode = 2, 3

LAD / FBD
SCL
Description
"MC_Halt_DB"(
Axis:=_multi_fb_in_,
Execute:=_bool_in_,
Done=>_bool_out_,
Busy=>_bool_out_,
CommandAborted=>_bool_out_,
Error=>_bool_out_,
ErrorID=>_word_out_,
ErrorInfo=>_word_out_);
Use the MC_Halt instruction to stop all
motion and to bring the axis to a stand-
still. The stand-still position is not defined.
In order to use the MC_Halt instruction,
the axis must first be enabled.
