OSN? Read Number Steps
Used in: Motion in open-loop operation (33)
Description: Queries the number of steps that still have to be performed by the
specified axis.
Format: OSN?[{␣<AxisID>}]
Arguments: <AxisID> Axis ID
The value for all axes will be queried if no arguments are specified.
Response: {<AxisID>=<uint>
␊
}
<AxisID> Axis ID
<uint> Number of steps still to be made
Troubleshooting: Illegal axis identifier
POS Set Real Position
Used in: Reference point definition options (40)
Description: Sets the current position of the axis (does not cause motion).
Long description POS can only be used when the reference point definition mode is
set to "0" (p. 155) .
The minimum ( TMN? (p. 164) ) and maximum ( TMX? (p. 164) ) com-
mandable positions are not influenced by POS. This means that tar-
get positions are possible that are permitted by the electronics but
cannot be reached by the mechanics, or could be reached by the
mechanics but are not permitted by the electronics.
