    Tips: Variable frequency drive applications

    1. Air conditioner load
      Office buildings, shopping malls, supermarkets and some factories have central air conditioner. In the summer electricity peak, large city air conditioner power consumption accounted for more than 40% of peak power. Therefore, using variable frequency drive to drag the air conditioning system, refrigeration pumps, cold water pumps and fans is a very good energy-saving technology.
    2. Crusher load
      Metallurgical mines and building material industry use a lot of crushers and grinding mills, these machineries have significant effect using variable frequency drive.
    3. Large furnace calciner furnace load
      Metallurgy, building materials, caustic soda and other large industrial rotary kiln uses DC motor, commutator motor, slip motor, cascade speed control and medium frequency unit speed control before. Because of these speed control mode or a slip ring have low efficiency, in recent years, many companies use frequency control, the effect is excellent.
    4. Compressor load
      Low-pressure compressors are widely used in various industrial sectors, high-pressure high-capacity compressors has more applications in steel, mining, fertilizer, ethylene industries. Using frequency control will bring low starting current, energy saving, optimizing equipment and other advantages.
    5. Rolling mill load
      The metallurgical industry uses AC-DC-AC VFD, and the multi-rack aluminum rolling unit uses general-purpose VFD to meet the low-frequency load starting. The variable frequency drive has advantages of inter-rack synchronous operation, constant tension control, simple and reliable operation.
    6. Winding engine load
      Iron mill blast furnace hoist equipment requires smooth boot and brake, balance speed adjusting and high reliability. These machineries use cascade, DC or rotor string resistance speed mode with low efficiency and poor reliability before. But, using VFD instead of the old speed control mode can achieve the desired results.
    7. Revolving furnace load
      Using AC variable frequency drive to replace DC unit in revolving furnace will get simple, reliable and stable operation.
    8. Roller load
      Roller load is mostly used in the iron and steel metallurgy industry. Using AC motor frequency control can improve equipment reliability and stability.

    ATO GK3000 VFD wiring instruction for single phase induction motor
    Single phase induction motor has specific wiring requirements in connecting with ATO single phase VFD to enable your single phase motor running properly, please follow below instructions step by step:
    VFD wiring instruction for single phase motor
    Step 1: Single phase motor has one or two capacitors, disassembly them. The VFD output can't have capacitor.
    Step 2: VFD Common Terminal: Running the VFD at 50Hz without connecting loads, measuring the output voltages of U-V, U-W, and V-W, two of three voltage values are the same, their common port is VFD's common terminal. Usually the default common terminal is V phase. (The output voltage is a bit higher for the non-common terminal)
    Step 3: Single phase motor has 3 windings and 6 taps. Base on the measuring results of the resistance by a multimeter, the biggest resistance is the secondary winding (Z1, Z2), the smaller resistance is the main winding (U1, U2), the smallest resistance (conducting) is centrifugal switch (V1, V2).
    Step 4: The Coupling End of the single phase motor secondary winding (Z2) and main winding (U2) is connected to the VFD's output common terminal (V phase).
    Step 5: The Coupling End of the single phase motor main winding (U1) and centrifugal switch (V1) is connected to the VFD's U phase. The Coupling End of the secondary winding (Z1) and capacitor is connected to the VFD's W phase. In case of the induction motor running in reverse, please exchange the VFD's U phase and W phase.

    Connecting the single phase motor input lines (L, N) to ATO VFD's V, U or W terminals. Generally V Phase should be connected, U or W is optional. Refer to below wiring picture:
