when the output is accidentally shorted to ground or driven to the opposite logic state
by external circuity.
Warning: do not drive the IO ports from any voltage source that can produce an output
in excess of the normal 0 to 5 Volt logic level range. In any case the voltage at the
TRIG ports must be limited to -0.25 to +5.25 Volts.

The trigger functionality assigned to the associated trigger output as
described below.
Input Trigger Modes
When configured as an input, the TRIG ports can be used as a general purpose digital
input, or for triggering a relative, absolute or home move. When used for triggering a
move, the port is edge sensitive. In other words, it has to see a transition from the
inactive to the active logic state (Low->High or High->Low) for the trigger input to be
recognized. For the same reason, a sustained logic level will not trigger repeated
moves. The trigger input has to return to its inactive state first in order to start the next
trigger. The mode is set in the
Trig 1 Mode
and
Trig 2 Mode
parameters as follows:
Disabled
- The trigger IO is disabled
Digital Input
- General purpose logic input (read through status bits using the
associated server message.
Trig In Rel. Move
- Input trigger for relative move. On receipt of the trigger, the
motor will move by the number of position steps entered in the
Trigger Input
Options - Relative Move Step
parameter.
Trig In Abs. Move
- Input trigger for absolute move. On receipt of the trigger, the
motor will move to the position entered in the
Trigger Input Options - Absolute
Move Position
parameter.
Trig In Zero Pos. Count
- Input trigger for Encoder Count Reset. On receipt of the
trigger, the counter will reset and all subsequent moves will be measured from the
current position.
When the trigger mode is selected to
Trig In Rel Move
or
Trig In Abs Move
, the relative
distance or absolute position to move, can be entered in the
Relative Move Dist
and
Absolute Move Pos
. parameters.
