Input Trigger Modes
When configured as an input, the IO 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 Trigger Mode parameter for each trigger as follows:
Disabled - The trigger IO is disabled
In - GPI - General purpose logic input (read through status bits using the
associated server message).
In - Relative 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 in the range 1 to 100000000
steps.
In - Absolute 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 in the range
In - Reset 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.
Output Trigger Modes
When the Trigger Mode parameters are configured as outputs, the IO ports can be
used as a general purpose digital output, or to indicate motion status or to produce a
trigger pulse at configurable positions as follows:
Out - GPO - General purpose logic output (set using the associated server
message).
Out - In Motion - Trigger output active (level) when motor 'in motion'. The output
trigger goes high (5V) or low (0V) (as set in the Trigger Polarity parameters) when
the stage is in motion.
Out - At Max Velocity - Trigger output active (level) when motor at 'max velocity'.
The max velocity limit that generates the trigger is dependent on the type of move
being performed, e.g. jog move, joystick move etc.
Note
The following three output modes are visible only if the Feedback Signal Mode
parameter is set to Limit Switch on the channel tab associated with the I/) channel.
