3.7 Parameters: 5-** Digital In/Out
3.7.1 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 + 24V, internally in the frequency
converter.
NOTE
Once this parameter has been changed, it must be activated
by performing a power cycle.
