Inverter connected to potentiometer maximum power

How do you connect a potentiometer to an inverter?

The most important connection at thePotentiometer end isthecentre terminal or “wiper”.Thewiperwilloutputavariablevoltage between 0 and 10 Volts and should be connectedtothe“AI1"terminalontheInverter. It is this voltage which provides the speed signalwith0Vbeingslowestand10Vfastest.

How do I change the output frequency of a 10V potentiometer?

To change this, edit Parameter F112. The default output frequency at 10V is 50Hz. To change this, edit ParameterF111. If the rotation of the Potentiometer is the opposite to that required (ie. turn anti-clockwise to increase speed instead of clockwise)reverseconnectionsGNDand10V.

Can a digital potentiometer cause oscillation?

When the circuit input is an ac signal, the parasitic capacitances of the digital potentiometer can cause undesirable oscillation in the output. This can be avoided, however, by connecting a small capacitor, C 1, between the inverter input and its output. A value of 10 pF was used for the gain and phase plots shown in Figure 3. Figure 3.

What is the maximum speed of the inverter?

Maximum speed 3000 min-1 with 50 Hz (3600 min-1 with 60 Hz), Controllable using a potentiometer via the inverter’s analogue inputs Ramp-up time / Ramp-down time = 10 s If more complex application settings are required, please refer to the parameter listing in the Operating Instructions.

What is the maximum frequency for the inverter?

Maximum frequency for the Inverter. Default is 50 which suits most applications. Minimum frequency for the Inverter. Default is 0.5 which suits most applications. Default is 5 seconds; increase or decrease if faster or slower acceleration is required. Default is 5 seconds; increase or decrease if faster or slower deceleration is required.

Which potentiometer should I use for my AC10?

This provides the benefit of allowing motor speedtobecontrolledfromamoreconvenient location such as a cabinet door (if theAC10 is cabinet-mounted)oronthemachineitself. Any potentiometer rated from 2kOhm to 5kOhmcanbeused-eg. 4.7kOhm . The number of turns depends on the application.
