    Servo Drive Terminal Details

    Servo driver terminals detail

    NO. Name Description
    1 Front Cover --
    2 Nameplate Indicates the SERVOPACK model and rating.
    3 Input Voltage --
    4 Charge Lights up when the main circuit power is turned on.
    Note:
    Even if you turn OFF the main circuit power supply, this indicator will light as long as the internal capacitor remains charged. Do not touch the main circuit or motor terminals while this indicator is lit. Doing so may result in electric shocks.
    5 Main Circuit Terminals The terminals depend on the main circuit power supply input specifications of the SERVOPACK.
    6 Servo Motor Terminals (U, V, W) The connection terminals for the servo motor main circuit cable (power line).
    7 Ground Terminal The ground terminals to prevent electric shock. Always connect this terminal.
    8 485 Communication (CN1,CN2) --
    9 I/O Signal Connector (CN3) Connect to reference input signals and sequence I/O signals.
    10 Encoder Connector (CN4) Rotary servo motor: Connect to the encoder in the servo motor.
    Linear servo motor: Connect to a serial converter unit or linear encoder.

    Tips: Installation and wiring of 200W-400W Servo Drive

    Installed in electrical control cabinet
    Due to the heating of electric devices in the electrical control cabinet and the thermal environment situation in the cabinet, the temperature around the servo driver will continue to rise. So, considering the configuration in the control cabinet and cooling of the driver, it should be ensured that air temperature is under 50 degrees and relative humidity is under 90 percent. Long-term safe working temperature should be under 45 degrees.

    Vibratory equipment around
    Whichever anti-vibration measure could be adopted to guarantee the servo driver is unaffected, and vibration is under 0.5G.

    Jamming devices around
    It strongly interferes with the power wire and control wire of the servo device when some jamming devices around the driver, which leads to wrong action of the servo driver. A noise filter and any anti–interference method could be applied to assure driver works normally. Do pay attention to the increasing of leakage current after a noise filter is added. To avoid this problem, an isolation transformer could be used.
    Take special notice: the control signal wire of the servo driver is very susceptible to interference, therefor wiring and shielding protection should be reasonable.

    Powerful and precise servo drive
    Perfect for my CNC upgrade. Handles 400W motor smoothly, setup was straightforward with clear manuals. Reliable performance for precision tasks.

    Reliable performance for the price point
    This servo drive works great with my 400W motor. Setting it up was super straightforward, and it keeps running steadily in our packaging equipment. The RS485 monitoring is pretty useful—though I do wish it let you take full control. It has really consistent torque, and the dual-voltage support is such a convenience. Definitely a solid pick for basic industrial uses.

    How can we specify the single phase 220V for your 3-phase servo driver?
    How can we specify the single phase 220V for your 3-phase servo driver? Is there any setting or wiring for that?

    ATO Responded
    When using single-phase 220V for input, you can directly connect the controller's power input terminals R, S, or R, T, without any setting parameters.
