Status Bits
MAH Changes to Single Axis Status Bits
Bit Name State Meaning
HomingStatus TRUE Axis is Homing.
JogStatus FALSE Axis is no longer Jogging.*
MoveStatus FALSE Axis is no longer Moving.*
GearingStatus FALSE Axis is no longer Gearing.
StoppingStatus FALSE Axis is no loner Stopping.
*During portions of the active homing sequence these bits may be set and cleared.
The MAH instruction uses the Move and Jog motion profile generators to move
the axis during the homing sequence. This also means that any disruption in the
Move or Jog motion profiles due to other motion instructions can affect the
successful completion of the MAH initiated homing sequence.
If in Passive homing mode, the MAH instruction simply sets the Homing Status
bit.
