4.5 Signals
4.5.1 ‘Sense’
The sense line (module C) is a measuring line which measures the voltage
drop across the positive line to the incremental encoder. Precondition is that
both supply lines have an equal cross section and an equal length resulting in
an the equal voltage drop. The output voltage of the Controller is then adjusted
so that 5 V are applied to the encoder terminals.
If the sense input is not wired then the regulator supplies a stabilized output
voltage of 5 V.
The following figure shows the possible connection of a 5 V encoder to the first
count input of module C:

4.5.2 ‘Fault’
The /fault signal at terminal 30 of the (1st) module P
1
becomes active (level
changes from High to Low) when the following situations occur:
•
the »Delta_s« contouring distance exceeds one of the programmed S
max+/-
values (storage locations 3/42 and 3/43)
•
a limit switch triggers (refer to section 4.11)
At the same time
−
the Controller changes into the stop or reset state,
−
the separation points in display B are flashing (only visible if the
corresponding axis is just displayed).
This state remains until either the
start or search for reference signal is applied
or the drive will be manually positioned.
