C-863.12 Mercury Controller

Version: 1.2.1

Troubleshooting: Illegal axis identifier
Notes:
The detection of the on-target state is only possible in
closed-loop operation (servo mode ON).
The on-target state is influenced by the settings for the
settling window (parameter 0x36) and the delay time
(parameter 0x3F). Details see "On-Target State" (p. 23).
POS (Set Real Position)
Description:
Sets the current position of the axis (does not cause
motion).
Format:
POS {<AxisID> <Position>}
Arguments:
<AxisID> is one axis of the controller.
<Position> is the new current position in physical units.
Response:
None
Troubleshooting: Illegal axis identifier
Notes:
It is only possible to set the current position with POS
when the referencing method "0" is selected, see RON (p.
183).
An axis is considered to be "referenced" when the position
has been set with POS (for more information, see
"Referencing" (p. 28)).
The minimum and maximum commandable positions
(TMN? (p. 198), TMX? (p. 199)) are not adapted when a
position is set with POS. This can result in target positions
which are allowed by the C-863.12 but cannot be reached
by the hardware. Target positions are also possible that
can be reached by the hardware but are refused by the C-
863.12. Furthermore, the zero position can be outside of
the physical travel range after using POS.
