Parameters for configuring the input and output using
NPN and PNP.
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
frequency converter.
NOTE
Once this parameter has been changed, it must be
activated by performing a power cycle.
