All analogue terminal functions can be programmed in menu 7.
Available digital terminal functions can be programmed in menu 8.

NOTE
The digital I/O at default has been configured to accept external signals
from main and auxiliary contactors to allow the regen mode to function
correctly. Before changing any routing, refer to Menu 8 descriptions.
The control circuits are isolated from the power circuits in the
drive by basic insulation (single insulation) only. The installer
must ensure that the external control circuits are insulated
from human contact by at least one layer of insulation
WARNING
(supplementary insulation) rated for use at the AC supply
voltage.
If the control circuits are to be connected to other circuits
classified as Safety Extra Low Voltage (SELV) (e.g. to a
personal computer), an additional isolating barrier must be
included in order to maintain the SELV classification.
WARNING
If any of the digital inputs or outputs (including the drive
enable input) are connected in parallel with an inductive load
(i.e. contactor or motor brake) then suitable suppression (i.e.
diode or varistor) should be used on the coil of the load. If no
CAUTION
suppression is used then over voltage spikes can cause
damage to the digital inputs and outputs on the drive.
Ensure the logic sense is correct for the control circuit to be
used. Incorrect logic sense could cause the motor to be
started unexpectedly.
Positive logic is the default state for Unidrive SP.
CAUTION
N
NOTE
The Secure Disable / drive enable terminal is a positive logic input only.
It is not affected by the setting of Pr 8.29 Positive logic select.
N
NOTE
The common 0V from analogue signals should, wherever possible, not
be connected to the same 0V terminal as the common 0V from digital
signals. Terminals 3 and 11 should be used for connecting the 0V
common of analogue signals and terminals 21, 23 and 30 for digital
signals. This is to prevent small voltage drops in the terminal
connections causing inaccuracies in the analogue signals.
