NOTE!
The CFW320 inverters are supplied with the digital inputs configured as active low (NPN). In order
to change the configuration, check the use of parameter P271 in the programming manual of the
CFW320.
Analog input Al1 is set for input 0 to 10 V, in order to change, check parameter P233 of the
programming manual.
For the correct connection of the control, use:
1. Gauge of the cables: 0

(14 AWG).
2. Maximum torque: 0

3 N.m (2
.
65 lbf.in).
3. Wiring of the connector of the control board with shielded cable and separated from the other wiring
(power, command in 110 V / 220 Vac, etc.), according to Item 3.2.6 Cable Separation Distance on page 22 .
If those cables must cross other cables, it must be done in perpendiculary among them, keeping the
minimum separation distance of 5 cm at the crossing point.
Connect the shield according to the Figure 3.4 on page 22 .
