Chapter 11 Motion Control Instructions
11-197
Thus, during cam operation, the execution of MC_SetPosition instruction for the master axis
and slave axis will not affect the cam operation. If the cam operation is triggered after the
MC_SetPosition instruction is executed, the cam will be affected by the axis position change
which is incurred by using the MC_SetPosition instruction.
MC_Stop and MC_Halt
As the MC_Stop and MC_Halt instructions are executed on the slave axis, the MC_CamIn
instruction is aborted, the cam relationship is disconnected and the slave axis decelerates till
it stops.
MC_Home
The MC_Home instruction cannot be executed on the slave axis but the master axis. As the
MC_Home instruction is executed on the master axis, the master axis position may have a
great change in a very short time, which may cause the vibration of the slave axis. Therefore,
the MC_Home instruction is recommended to execute after the synchronous relationship
between the two axes is disconnected.
Other precautions
See the rule for different types of axes working as the master axis or slave axis in the cam relationship
in the following table.
