1.
Configure the digital output line (<TrigOutID>) that is to be used as the trigger output:
−
Send
CTO <TrigOutID> 2 A
, where
A
indicates the axis to be moved.
−
Send
CTO <TrigOutID> 3 0
, where 0 specifies the
Position Distance
trigger
mode.
−
Send
CTO <TrigOutID> 1 S
, where
S
indicates the distance.
−
Send
CTO <TrigOutID> 8 Start
, where
Start
indicates the start value.
−
Send
CTO <TrigOutID> 9 Stop
, where
Stop
indicates the stop value.
2.
If you want to activate the conditions for trigger output, send
TRO <TrigOutID> 1
.
Example
A pulse on digital output line 1 is output every time the axis 1 of the positioner has covered a
distance of 0.1 µm, as long as axis 1 is moving in positive direction of motion within the range of
0.2 µm to 0.55 µm (start value < stop value).

"Position Distance" trigger mode with start and stop values for negative motion
direction of the axis
The above example is presented with interchanged start and stop values in the following.
Triggering occurs in negative motion direction of the axis (stop value < start value) in the range
between 0.55 µm and 0.2 µm.
Example:
➢
Send:
CTO 1 2 1
CTO 1 3 0
CTO 1 1 0.0001
CTO 1 8 0.00055
CTO 1 9 0.0002
