NOTE!
The CFW300 inverters are supplied with the digital inputs configures as active
„
low (NPN). In order to change the configuration, check the use of parameter
P271 in the programming manual of the CFW300.
Analog input AI1 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: 0.5 mm² (20 AWG) to 1.5 mm² (14 AWG).
2. Maximum torque: 0.4 N.m (3.54 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
Separation Distance on page
in perpendicularly among them, keeping the minimum separation distance of 5 cm at the
crossing point. Connect the shield according to the
