Motion curve and timing chart
As CamIn_Ex changes from FALSE to TRUE at t1, the MC_CamIn instruction is executed and
at the moment, both of the master axis and slave axis positions are 0. The value of
ActivationPosition is 100 and ActivationMode is 0, so the slave axis will not start to execute the
engagement action until the master axis position is 100 (the master axis position at t1 +
ActivationPosition).
As Vel_Ex changes from FALSE to TRUE at t2, the MC_MoveVelocity instruction execution
starts. At the moment, the master axis position is 0 and the slave axis continues waiting for the
execution of the engagement action. After that, the master axis moves from 0 in the positive
direction under the control of the MC_MoveVelocity instruction.
