Check Digital Input Event
This exit condition checks for the state of the digital input.
As soon as the specied state is reached, the axis proceeds
with the next segment.
<checkDigInput input="1" value="o"/>
Attribute
Mandatory/
optional
(+default
value)
Value range/
allowed values
Description
input M 1/2 Selects if the
1
st
or the 2
nd
digital input is
aected.
value M On/o/toggle Switches the
digital output
on, o, or
changes the
current state.
Table 2.47 Attributes for Pattern Search Action
Counter Exceeds Limit
This exit condition checks for the digital input counters
that are controlled via actions (see section Digital Input
Counter in chapter 2.4.5.5 Advanced CAM). As soon as the
threshold value is reached or exceeded, the axis proceeds
with the next segment.
<checkCounter input="1" threshold="500"/>
Attribute
Mandatory/
optional
(+default
value)
Value range/
allowed values
Description
input M 1/2 Selects if the
1
st
or the 2
nd
digital input
counter is
aected.
threshold M Positive integer Denes the
threshold of
the counter
(greater or
equal).
Table 2.48 Attributes for checkCounter
Check Analog Input Event
This exit condition checks for the state of the analog input.
As soon as the
specied state is reached, the axis proceeds
with the next segment.
<checkAnaInput input="1" threshold="0.5"
condition="above">
Attribute
Mandatory/
optional
(+default
value)
Value range/
allowed values
Description
input M 1/2 Selects if the
1
st
or the 2
nd
analog input is
aected.
threshold M 0–1 Threshold to
be exceeded or
underrun.
Scaled from 0
to 1.
condition M Above/below Selects if the
segment
should be left
if the threshold
has been
exceeded or
underrun.
Table 2.49 Attributes for checkAnaInput
Exit: Velocity Below/Above Limit
This exit condition checks if the velocity is below or above
the specied absolute. As soon as the value is above or
below the threshold, the axis proceeds with the next
segment.
<checkVelocity threshold="500" condition="above"/>
Attribute
Mandatory/
optional
(+default
value)
Value range/
allowed values
Description
threshold M Float Velocity
threshold to be
exceeded or
underrun. The
velocity must
be given in
rps.
condition M Above/below Selects if the
segment
should be left
if the threshold
has been
exceeded or
underrun.
Table 2.50 Attributes for checkVelocity
Torque Below/Above Limit
This exit condition checks if the torque is above or below
the specied absolute value. As soon as the value is above
or below the threshold, the axis proceeds with the next
segment.
<checkTorque threshold="500" condition="above"/>
