3.5.2.5 MC_MoveRelative
Except for the input DISTANCE this is identical to MC_MoveAbsolute. The setpoint position results from the
addition of the present actual position and the transferred DISTANCE.
Table 75 MC_MoveRelative
3.5.2.6 MC_MoveAdditive
Except for the input DISTANCE this is identical to MC_MoveAbsolute. The setpoint position results from the
addition of the present setpoint position and the transferred DISTANCE.
