(a) NPN Configuration
NOTE!
The CFW100 inverters are supplied with the digital inputs configured as active low (NPN). In order to
change it, see the use of parameter P271 in the programming manual of the CFW100.
For the correct connection of the control, use:
1. Gauge of the cables: 0.5 mm² (20 AWG) to 1.5 mm² (14 AWG).
2. Maximum torque: 0.5 N.m (4.50 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
those cables must cross other cables, it must be done in perpendicularly among them, keeping the minimum
separation distance of 5 cm at the crossing point. Connect the shield according to the figure below:

4. Relays, contactors, solenoids or coils of electromechanical brake installed close to the inverters may occasionally
generate interference in the control circuitry. To eliminate this effect, RC suppressors (with AC power supply)
or freewheel diodes (with DC power supply) must be connected in parallel to the coils of these devices.
5. When using the external HMI (refer to
the inverter must be separated from the other cables in the installation, keeping a minimum distance of 10 cm
(3.95 in).
