ScaDiag would display the warning “conveyor in reverse”.
C8:
Dead time (msec)
[Dead time ms]
Input values:
0 to 999 in steps of 1
[20ms]
Function:
to define the dead time as fixed value in milliseconds.
Comments:
This parameter is accessible only if previously in menu C3 fixed dead time (C3 = 02)
was activated.
C9:
Pulse delay
[Pulse Delay]
Input values:
0 = off
output pulse issued immediately after end of the edge
1 = on
output pulse issued with delay relative to end of the edge
Function:
to define whether the output pulse is issued right after the end of an edge or with the
delay as specified in menu C10 or C11.
Comments:
A delayed output pulse is required in the following two applications:
1.)
to trigger an action which is delayed relative to the end of the edge (for
example: to trigger an ink jet printer for labeling newspapers)
2.)
to suppress tail edges (for details see C13)
This parameter is accessible only if menu C2 false pulse suppression was
previously activated (C2 = on). Depending on the mode of false pulse suppression
choosen in menu C3, the output pulse delay will be specified in menu C10 in
milliseconds or in menu C11 in millimeters.
The following sketch shows schematically the signal sequence of undelayed and
delayed output pulse sequences. Note that both dead time and the output pulse are
triggered with the end of an edge. However, the output pulse issue might be delayed
while the dead time always starts right with the trigger.
C10:
Pulse delay (msec)
[Pulse Delay ms]
Input values:
0 to 999 in steps of 1
[100ms]
Function:
to define the value of the output pulse delay in milliseconds.
