MC_Power commands the axis to perform the <search home> sequence. The
details of this sequence are manufacturer dependent and can be set by the axis
parameters. The "Position" input is used to set the absolute position when a
reference signal is detected, and the configured Home offset is reached.
MC_Home operation
• After MC_Power is issued, the axis Homed status is reset to 0 (not homed).
In most cases, after the axis is powered on, the MC_Home function block
needs to be executed to calibrate the axis position and the Home reference.
• The MC_Home function block can only be aborted using a MC_Stop or a
MC_Power function block. If it is aborted before it completes, the
previously searched Home position is considered invalid and the axis
Homed status is cleared.
