Version 1.3 Changes
Overview
The changes to the N3 inverter for firmware Version 1.3 consist of some hardware and
A
(advanced) parameter
additions and modifications. Basically for models in the 3
– 75 HP range, the control terminal digital and analog
grounds were isolated from each other and the
S6/AI2
multifunctional
input terminal was separated into two terminals
where
S6
is exclusively a digital input and
AI2
is exclusively an analog input. Also some
A
(advanced) parameters
were added and / or modified. The following will describe the details of the changes
Hardware Changes:
Models in the 3
– 75 HP range:
Prior to Version 1.3, control terminal
S6/AI2
served as a multi function terminal and could be programmed to be a
digital or analog input and control terminal
COM
was the common connection for both analog and digital inputs. In
Version 1.3 separate control terminals
AI2
(analog input 2) and
AGND
(analog ground) were added to the N3
Models covering the 3
– 75 HP range. Also terminal
S6
is a digital input only. (See Fig. 10.2.3,
Sec. 10.0
Control
Terminals, and General Wiring Diagram
6.0
)
Models in the 1 - 2 HP range:
There are no hardware changes in Version 1.3 for models in the 1-2 HP range. As in previous versions control
terminal
S6/AI2
is
a multi function terminal and can be programmed to be a digital or analog input. This is also
applicable to 3
– 75 HP Models prior to Version 1.3. (See
Sec. 10.0
Control Terminals and General Wiring
Diagram

)
Parameter Changes: (See Sec. 19.0 for parameter details)
