3-17 Reference Resource 3
Option: Function:
Select the reference input to be used
for the third reference signal.
parameter 3-15 Reference Resource 1,
parameter 3-16 Reference Resource 2
and parameter 3-17 Reference Resource
3 define up to three different reference
signals. The sum of these reference
signals defines the actual reference.

5-00 Digital I/O Mode
Option: Function:
NOTICE!
Once this parameter has been changed,
perform a power cycle to activate the
parameter.
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 adjustable
frequency drive.
5-01 Terminal 27 Mode
Option: Function:
NOTICE!
This parameter cannot be adjusted while the
motor is running.
[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:
This parameter is available for FC 302 only.
[0] Input Defines terminal 29 as a digital input.
[1] Output Defines terminal 29 as a digital output.
6.1.4 Digital Inputs
