Setting up Compax3 C3I22T11
132 192-120114 N5 C3I22T11 June 2008
The limit switches must be positioned so that they cannot be released towards the
side to be limited.
Limit switches functioning as direction reversal switches during homing run, will not
trigger a limit switch error.
The error can be acknowledged with activated limit switch.
The drive can then be moved out of the end switch range with a normal positioning.
The direction of the movement is verified!
Only the direction towards the travel range is allowed.
Debouncing: Limit switch, machine zero and input 0
A majority gate is used for debouncing.
The signal is sampled every 0.5ms
The debounce time determines the number of scans the majority gate will perform.
If the level of more than half of the signals was changed, the internal status will
change.
The debounce time can be set in the configuration wizard within the range of 0 ...
20ms.
The value 0 deactivates the debouncing.
If the debouncing time is stated, the input I0 can be debounced as well (checkbox
below).
4.1.7.4 Change assignment direction reversal / limit switches
If this function is not activated, the direction reversal / end switches are assigned
as follows:
Direction reversal / limit switch on E5 (X12/12): negative side of the travel range
Direction reversal / limit switch on E6 (X12/13): Direction reversal / limit switch on
E6 (X12/13):
If this function is activated, the direction reversal / limit switches are assigned as
follows:
Direction reversal / limit switch on E5 (X12/12): positive side of the travel range
Direction reversal / limit switch on E6 (X12/13): negative side of the travel range
4.1.7.5 Change initiator logic
The initiator logic of the limit switches (this does also apply for the direction rever-
sal switches) and the machine zero initiator can be changed separately.
 Limit switch E5 low active
 Limit switch E6 low active
 Home switch E7 low active
In the basic settings the inversion is deactivated, so that the signals are ”high acti-
ve”.
With this setting the inputs I5 to I7 can even be switched within their logic, if they
are not used as direction reversal/limit switches or machine zero.
