Outdoor rated VFD - standard operating panel
IP66 enclosures offer a higher degree of protection against harsh environmental conditions. They are dust-tight and provide complete protection against powerful water jets, making them suitable for outdoor use or locations with high levels of dust and moisture, even for washdown applications. The sealed design prevents damage from external elements, ensuring the reliability and longevity of the frequency inverter in challenging settings. However, to ensure sufficient cooling and heat dissipation, it is important to protect them from direct sunlight.
How to control these FI-E44 IP66 frequency inverters?
These frequency inverters can be controlled via the inputs or via the buttons on the front panel. A digital input signal can be used to generate a start / stop command while an analogue control signal can be used to define the requested motor speed.
The behaviour of the inputs can be adjusted by selecting one of the available macros. This offers the advantage that the most important settings are pre-configured automatically. It takes away the need of programming the functionality for the different inputs. These functionalities are pre-defined in the application macros. In the default macro, input 1 is used to start the motor. An optional 10K potentiometer can be connected to terminals 5, 6 and 7 to adjust fan speed. When input 3 is activated, the motor runs at the predefined speed in parameter 20. When input 3 is not activated (or not connected), the motor speed can be adjusted via the external potentiometer (or analogue control signal).
By selecting a different macro, the inputs will be given different functionalities. Available macros can be found in the manual.
