    Tips: Six attentions of installing VFD in automatic control system

    1. For the frequency given signal should be used as far as possible 4-20mA international standard signal. Should make sure the signal line shield ground, to avoid the interference signal into the VFD. The production site has an interference signal, the interference signal will affect the stability of the control, so need to use input filter, and set its range to be 0.00-5.00s. If using VFD built-in PID function should use the feedback filter to increase the control stability of the built-in PID, the setting range is 0.0-60s. However, it should be noted that the filter time is set too long, the control is stable, but the system response is worse; the filter time is set too short, the system response is fast, but the control is unstable. So it should be based on the actual scene to make adjustments.
    2. To set the corresponding manual, automatic switching operating function. Optional manual, automatic, forced manual functions of manual operator. If necessary, could also consider the redundant operation function of the current and voltage setting, that is, the VFD frequency setting signal use current setting in normal, using voltage setting in abnormal manual operation. That is, add a potentiometer for setting g the VFD frequency, so the VFD frequency reference signal has two types, current signal and voltage signal. Because there are two types of frequency setting signals input in the VFD, increasing its redundancy degree.
    3. Must set the "overhaul switch", that is, set the "on-site overhaul switch" next to the operating equipment, when switch it to the "overhaul" position, equal to cut off the VFD running signal circuit. If someone misuse, the equipment can't run, to ensure that the safety of mechanical equipment maintainer.
    4. Make full use of the VFD input and output control terminals function, to carry out some alarm and interlock function, to reduce wiring and improve reliability.
    5. For single or simple control system, can take full advantage of the VFD built-in PID control function to reduce the control system equipments and reduce investment.
    6. Some VFD have input terminals R0, T0 of control power. So should connect control power to VFD R0, T0 side in front of the main power supply. So that the VFD still has a display function after the trip, in order to analyze the cause of the malfunction and take countermeasures.

    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:
