How do you program a variable speed drive?

Take these steps to prepare your system for VFD Programming:

  1. If there is a jumper wire between +24 volts and LI-1 in the VFD terminals, disconnect one end of the jumper.
  2. Turn the main control panel switch to “on.”
  3. Start the control panel to activate contractors.
  4. Once the VFD is ready you may begin VFD programming.

How do you connect an electric motor to a VFD?

How to Wire a VFD

  1. STEP 1: Make sure everything is correctly sized and accounted for.
  2. STEP 2: Make sure you have a properly-sized circuit breaker rated for your amps and VFD.
  3. STEP 3: Run Wires – (3) power wires and (1) ground wire from your breaker panel to your VFD.
  4. STEP 4: Run wires from VFD to motor.

What is preset speed?

preset speed. This means that when only the run command (DI1) is enabled the drive should ramp up the motor to 30 hz. if DI2 has been set to 2 preset speeds and preset speed 2 is set to 40 hz, then when DI1 and DI2 are enabled the drive will run the motor at the second preset speed.

How do you set up a variable frequency drive?

6 Step Basic Setup Of An SMV Variable Frequency Drive

  1. Turn Off All Line Power. SMVector Variable Frequency Drives come in four different voltages: 120 VAC, 240 VAC, 480 VAC and 600 VAC.
  2. Wire The Input Line Voltage.
  3. Wire The AC Motor.
  4. Jumper The Drive Enable.
  5. Power Up The Drive.
  6. Finish Your Setup.

Why is volts Hertz used instead of constant voltage?

In order to keep the magnetic flux constant, the V/Hz ratio must remain constant. This keeps torque production stable, regardless of frequency. V/Hz control of a VFD drive avoids this variation in the magnetic field strength by varying the voltage along with the frequency, in order to maintain a constant V/Hz ratio.
