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

Change initiator logic

The initiator logic of the limit switches (this does also apply for the direction
reversal 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
active".
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.

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).
Ramp (deceleration) upon error and "switch to currentless"
3: Deceleration upon error and upon deactivation of MC_Power (see page 165)
Please observe:
The configured error ramp is limited. The error ramp will not be smaller than the
deceleration set in the last motion set.
