Scope of Application
- Temperatur controlled ventilation systems: Depending on the air temperatur the speed is modified in order to keep the fixed set-point temperature.
- Circulation Pump for Bathrooms: Controlling the volume circulated depending on the polution degree and the time of day.
- Elevator control
This compact drive system can be used where the control of speed is required.
The internal controller for speed guarantees a strong constancy of speed within a wide range of load.
By means of the integrated PI-Controller you can solve drive problems which have requirements
for proportional speed. You can place a transducer near the input of the actual value.
This way you can give the physical value you want to control directly into the inverter.
(for example: pressure)
Furthermore you can use the inverter for control of the through flow volume, Temperature in ventilation systems,
pressure in hydraulic systems, speed on different kind of machines
and also start-up processes of devices.
The inverter 4.8 replaces the previously types 4.4 and 4.6.
