 While a single-axis mode is active (i.e. when the pattern is being generated and output), the axis move status character (accessed by ''RDSTAT [axis]+'') is set to <wrap reply> A</wrap>.
-When single-axis mode is active then moving the axis (either using ''MOVE'' or ''MOVEREL'' or by using the joystick or wheels) will automatically update the offset.  Thus, the single-axis pattern always has the same position on start-up as where it last was used, unless the SAO command has been used in the interim to select a new offset.  However, moving the axis position while the single-axis mode is idle does not change the offset.

 For MicroMirror cards with fast DACs (usually axes A and C, or axes P and Q), the single-axis functions update the fast DACs at a rate of 40kHz beginning with firmware version 2.8.  Otherwise, the DAC update rate is 4kHz divided by the number of card axes. e.g. 1kHz for typical 4-channel SPIM Micro-Mirror cards and 4kHz for ADEPT piezo cards (but the mechanical response of piezos is much slower than 4kHz).  The phototargeting builds have only two fast DACs, usually axes H and I, and include provision for drawing circles/ellipses to perform ring TIRF.
