Diagram of the procedure with switch:
If
Switch
= Y and
Zero
= Y or
Origin
= Y, the speed reversal is made by the switch
detection or by a limit switch.
Output pos.
Defines the position where the output must be triggered if it has been programmed (see above).
Start condition
The inputs that are not defined as sequences selection inputs can be programmed here in order
to define a starting condition for the programmed sequence.
Example : As the inputs 1 to 5 are sequences selection inputs, the inputs 6 to 8 can be used for
the starting condition.
Conditions:
inputs 6 to 1
inputs 8 to 0
input 7: unused
"Start conditions "0.1....." (inputs 7 and 1 to 5 are not concerned by the starting condition).
In these conditions, this sequence can only be executed if input 6 is set at 1 and input 8 at 0.
A conditional sequence connection can be programmed via the inputs by combining the "start
condition" for the inputs with the « counter link » parameter. The counter parameter must be
empty. The sequence will be executed if the "start condition" inputs are ready. Otherwise, it
will not be executed and the programme directly switches on to the sequence indicated by the
"counter
link"
parameter.
Example :
Sequence 1
Next
= 2
Counter
=
Counter link
= 4
Start condition
= 1 ....... (IN8 input)
When executing this sequence:
if IN8 input = 1, sequence 1 will be executed and the programme switches on to sequence 2.
if IN8 input = 0, sequence 1 will not be executed and the programme directly switches on to
sequence 4.
If, in the example above, the parameter "counter link" is empty, the programme waits until the
"start condition" inputs are ready for executing sequence 1.
Stop condition
The motion types "Speed" and "Torque" allow the use of the inputs defined as Start conditions
as conditional STOP inputs for stopping the axis.
