7-6 Changing the Personality
21: Default X Microstep Factor, range 1.0000 to 32.0000, factory 8.0000
This parameter sets the default X microstep factor (i.e. resolution) which is applied at
power up and an RE command with no parameters (but not at IN!).
22: Default Y Microstep Factor, range 1.0000 to 32.0000, factory 8.0000
This sets the default Y microstep factor; see parameter 21.
Travel Limits
23: Default Travel Limit <xmin>, range 0 to 32767, factory 0
This sets the default <xmin> travel limit value to be applied at power up, at IN, and at a TL
command with no parameters. See the TL command in Chapter 3.
24: Default Travel Limit <ymin>, range 0 to 32767, factory 0
This sets the default <ymin> travel limit; see parameter 23.
25: Default Travel Limit <xmax>, range 0 to 32767, factory: see text
This sets the default <xmax> travel limit; see parameter 23. The factory setting is
described under the TL command in Chapter 3.
26: Default Travel Limit <ymax>, range 0 to 32767, factory: see text
This sets the default <ymax> travel limit; see parameter 23. The factory setting is
described under the TL command in Chapter 3.
User Definable
27: User Definable 1, range -32768 to 32767, factory 0
This parameter is not used by the System. It can be set to any value and can be read back
later via the OP command. You could use this, for example, to store your own system
status or configuration codes in non-volatile memory.
28: User Definable 2, range -32768 to 32767, factory 0
This is another user-definable parameter. See parameter 27.
Motor Direction
29: X Motor Direction, range 0 to 255, factory 0
If this parameter is nonzero the rotation of the X motor is reversed. It should be set so that
X-axis travel toward lower- numbered coordinates produces motion towards the X Home
switch.
When separate Automove motors are shipped from the factory they are wired such that
negative motion produces a clockwise rotation as viewed from the protruding end of the
shaft. If this is inappropriate for your X home switch location then set personality
parameter 29 to a nonzero value.
