Command Parameters
# Parameter Description Data

1 Position Change (position units) REAL Any
Description
This command offsets the Actual Position of the axis by the specified Position Change.
This command can be sent anytime, including while in motion in closed-loop control. The
method by which this offset is performed depends on the axis type:
• Incremental axes:
The offset is done by adjusting the accumulated Actual Position and the Target and
Command Positions.
• Absolute linear axes:
The offset is done by adjusting the Position Offset parameter, which effectively adjusts
the Actual Position, and by adjusting the Target and Command Positions by the same
amount.
• Absolute rotary axes:
The offset is done by adjusting the Count Offset parameter by an amount that will
result in the Actual Position changing by the requested amount. The Target and
Command Positions will be adjusted by the same amount.
The Set Actual Position (49) command is much more commonly used than the Offset
Position command. If you need to simply change the current Actual Position, use the Set
Actual Position (49) command instead. Notice also that the Position Offset or Count Offset
parameter can be set directly as well by writing directly to that register. However, if they
are written to directly, the axis must be in the Direct Output state.
