6.4 5-** Digital I/O Mode
6.4.1 5-0* Digital I/O Mode
Parameters for configuring the input and output using
NPN and PNP.
These parameters cannot be adjusted while motor is
running.
5-00 Digital I/O Mode
Option:
Function:
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.
NOTE!
Once this parameter has been changed, it must be
activated by performing a power cycle.
This parameter cannot be adjusted while the motor is
running.
5-01 Terminal 27 Mode
Option:
Function:
[0]
*
Input
Defines terminal 27 as a digital input.
[1]
Output
Defines terminal 27 as a digital output.
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.
6.4.2 5-1* Digital Inputs
Parameters for configuring the input functions for the
input terminals.

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
min. 2 ms. The filter stops when Stop
inverse is activated.
[23]
Set-up select
bit 0
Select Set-up select bit 0 or Select Set-up
select bit 1 to select one of the four set-
ups. Set
to Multi Set-up.
[24]
Set-up select
bit 1
(Default Digital input 32): Same as Set-up
select bit 0 [23].
[32]
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.
