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.
[0]
*
PNP Action on positive directional pulses
(↕)
. PNP systems
are pulled down to GND.
[1]
NPN Action on negative directional pulses
(↕)
. NPN
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.

5-02 Terminal 29 Mode
Option:
Function:
[0]
*
Input
Defines terminal 29 as a digital input.
[1]
Output
Defines terminal 29 as a digital output.
6.5.2 5-1* Digital Inputs

Table 6.8 Digital Input Functions
Functions dedicated to only one digital input are stated in
the associated parameter.
5-10 Terminal 18 Digital Input
Option:
Function:
[0]
No
operation
No reaction to signals transmitted to the
terminal.
[1]
Reset
Resets filter after a trip/alarm. Not all alarms
can be reset.
[6]
Stop inverse Stop Inverted function. Generates a stop
function when the selected terminal goes
from logical level 1 to 0.
[8]
*
Start
(Default Digital input 18): Select start for a
start/stop command. Logic 1=start, logic
0=stop.
[9]
Latched
Start
The filter starts, if a pulse is applied for
minimum 2 ms. The filter stops when stop
inverse is activated.

Master cmd
pulse in
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
