1.
Configure the digital output line (<TrigOutID>) to be used as the trigger output:
−
Send
CTO <TrigOutID> 2 A
, where
A
indicates the axis to be moved.
−
Send
CTO <TrigOutID> 3 8
, where 8 specifies the
Single Position
trigger
mode.
−
Send
CTO <TrigOutID> 10 TriPos
, where
TriPos
indicates the position at
which the output line is to become active.
2.
If you want to activates 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

Setting Signal Polarity
The polarity of the signal at the digital output which is used for triggering can be selected with
the
Polarity
CTO parameter. The polarity can have the following values:
▪
active high = 1 (default setting)
▪
active low = 0
➢
Configure the digital output line (<TrigOutID>) to be used as the trigger output:
−
Send
CTO <TrigOutID> 7 P
, where
P
indicates the polarity.
Example:
The signal polarity for digital output line 1 is to be set to active low.
➢
Send:
CTO 1 7 0
