3. STANDARD APPLICATIONS OF THE INVERTER (without reconfiguring the inverter)
3.1 MANUAL PROPORTIONAL CONTROL WITH BUILT IN POTENTIOMETER
3.1.1 Features
This configuration allows the user to vary the fan rotating speed using the inverter potentiometer.
3.1.2. Wiring diagram
Follow the inverter-motor wiring diagram shown in the following illustrations depending on the type of motor used
and whether this motor has thermal protection:
- Fig.1.1. Single phase power supply 1/230/50-60, three phase motor 230/400V without thermal protection
(automatic reset)
- Fig.1.2 Three phase power supply 3/400/50-60, three phase motor 230/400 or 400V without thermal protection
(automatic reset)
- Fig.1.3. Single phase power supply 1/230/50-60, three phase motor 230/400V with thermal protection (manual
reset)
- Fig.1.4. Three phase power supply 3/400/50-60, three phase motor 230/400 or 400V with thermal protection
(manual reset )
Check that
the “ SW1 ” switch is in the “ SOURCE ” position .
Install the indicated jumpers in the inverter terminal box.
Power the frequency inverter with suitable voltage for the inverter model in question.
The speed is adjusted using the
potentiometer
RUN / STOP keys to start
