d) Send
CTO <TrigOutID> 10 TriPos
, where TriPos indicates the position for the
output of the first trigger pulse.
e) Send
CTO <TrigOutID> 9 Stop
, where Stop indicates the stop value.
2. If you want to enable the conditions for trigger output, send
TRO <TrigOutID> 1
.
Example 1: The first trigger pulse is to be output on digital output line 1 if the absolute
position of axis 1 is 1.5 mm. A pulse should then be output on this line every time axis 1 has
covered a distance of 0.1 µm in the positive direction. The last trigger pulse is to be output if
the absolute axis position is 2.5 mm.
Send:
CTO 1 2 1
CTO 1 3 7
CTO 1 1 0.0001
CTO 1 10 1.5
CTO 1 9 2.5
TRO 1 1
Example 2: The first trigger pulse is to be output on digital output line 2 if the absolute
position of axis B is 0.4 mm. A pulse should then be output on this line every time axis B has
covered a distance of 1 µm in the negative direction. The last trigger pulse is to be output if
the absolute axis position is 0.1 mm.
Send:
CTO 2 2 B
CTO 2 3 7
CTO 2 1 -0.001
CTO 2 10 0.4
CTO 2 9 0.1
TRO 1 1
Setting Up "Single Position" Trigger Mode
In the Single Position trigger mode, the selected digital output line is active when the axis
position has reached or exceeded a specified position (TriggerPosition).
The unit for TriggerPosition depends on the settings for the Numerator Of The Counts-Per-
Physical-Unit Factor parameter (0xE) and the Denominator Of The Counts-Per-Physical-Unit
Factor (0xF) parameter. Default is mm.
1. Configure the digital output line <TrigOutID> to be used as trigger output:
a) Send
where A indicates the axis to be moved.
b) Send
CTO <TrigOutID> 3 8
, where 8 determines the Single Position trigger mode.
c) Send
CTO <TrigOutID> 10 TriPos
, where TriPos indicates the position at which the
output line is to become active.
2. If you want to enable the conditions for trigger output, send
TRO <TrigOutID> 1
.
Example: Digital output line 1 is to become active when the absolute position of axis 1 is at
least 1.5 mm.
Send:
CTO 1 2 1
CTO 1 3 8
CTO 1 10 1.5
TRO 1 1
Setting Signal Polarity
The polarity of the signal at the digital output used for triggering can be selected with the
Polarity CTO parameter. The polarity can have the following values:
