7-10 Changing the Personality
38: Digital Input Sense, range 0 to 255, factory 255
This determines the logic sense of the Digital Inputs. If a given bit of parameter 38 is a 1
then the corresponding Digital Input is Low True (i.e. Low = True, High = False). If the
bit is a 0 then the Input is High True.
This logic sense applies to all modes of using the Digital Inputs: the MN, ON, WN, XI,
XU, and XW commands as well as function triggering via parameters 36 and 37. Thus a
False-to-True transition could be caused either by a High-to-Low or Low-to-High voltage
change.
No functions are triggered as the immediate result of changing parameter 38. In other
words, if an Input is sitting False and you change the definition so that it is now True, no
function is triggered. The input must subsequently go False, then True again in order to
trigger a function.
Autostart
39: Autostart Sequence I.D., range -1 to 255, factory -1
If this parameter is in the range 0 to 255, it specifies the I.D. of a Download Sequence
which is to be executed automatically after subsequent power ups. If it is -1, no Download
Sequence is automatically executed.
The Autostart sequence can be temporarily suppressed by holding down the FAST button
(the unlabeled button in the center of the four Arrow buttons) while turning on the power.
You must hold the button for several seconds to be sure the Autostart sequence is
suppressed.
Additional Z Axis Parameters
40: Z Axis Arrow Slow Step Delay, range 0 to 65535, factory 200
This sets the time delay between Z axis slow Arrow button steps (either half steps or full
steps). It is analogous to parameter 2. The delay is multiplied by approximately 100
microseconds.
In order to use the Arrow buttons to control the Z axis you must set the Arrow mode
appropriately; see the AM command in Chapter 3. Z axis Arrow single step delay is
controlled by parameter 1.
41: Z Axis Arrow Fast Step Delay, range 0 to 65535, factory 25
This sets the time delay between Z axis fast Arrow button steps. See parameter 40. The
parameter is multiplied by approximately 100 microseconds.
42: Z Axis Arrow Direction Swap, range 0 to 255, factory 0
If this parameter is zero the Down Arrow button moves the Z axis motor toward
lower-numbered Z coordinates and the Up Arrow, toward higher. If the parameter is
nonzero the functions of the Up and Down Arrows are swapped. You should pick an
appropriate value for parameter 31 before choosing a value for parameter 42.
In order to use the Arrow buttons to control the Z axis you must set the Arrow mode
appropriately; see Arrows in Chapter 4 and the AM command in Chapter 3. Z axis Arrow
single step delay is controlled by parameter 1.
