6.5 5-** Digital I/O Mode

6.5.1 5-0* Digital I/O Mode
Parameters for configuring the input and output using
NPN and PNP.
5-00 Digital I/O Mode
Option: Function:
This parameter cannot be adjusted while the unit is
running.
Digital inputs and programmed digital outputs are
pre-programmable for operation either in PNP or NPN
systems.

are pulled down to GND.
NPN Action on negative directional pulses (↕). NPN
[1]
systems are pulled up to + 24 V, internally in the
filter.
NOTICE
Once this parameter has been changed, it must be
activated by performing a power cycle.

6.5.2 5-1* Digital Inputs
Parameters for configuring the input functions for the
input terminals.
The digital inputs are used for selecting various functions
in the filter. All digital inputs can be set to the following
functions:

function when the selected terminal goes
from logical level 1 to 0.
(Default Digital input 18): Select start for a
start/stop command. Logic 1=start, logic
0=stop.
The filter starts, if a pulse is applied for
minimum 2 ms. The filter stops when stop
inverse is activated.
Select Set-up select bit 0 or Select Set-up
select bit 1 to select one of the 4 set-ups.
Set parameter 0-10 Active Set-up to [9] Multi
Set-up.
(Default Digital input 32): Same as [23] Set-up
select bit 0.
Time-based pulse input measures the
duration between flanks. This gives a higher
resolution at lower frequencies, but is not as
precise at higher frequencies. This principle
has a cut-off frequency, which makes it
unsuited for encoders with very low
resolutions (e.g. 30 PPR) at low speeds.
Do not program this setting. It is done
automatically for paralleling. See
parameter 300-40 Master Follower Selection
and parameter 300-41 Follower ID for more
information about paralleling.
