AC Servo System Functions
  • ▶ To meet diversified command and control mode

    ● Position / speed / torque control mode;
    ● Mixed control mode: position / speed, speed / torque, position /torque control mode;
    ● Command source selection: internal / external position command,internal / analog speed command; internal/analog torque command.
    ● Analog torque limit / analog speed limit
    ● Multiple sets of electronic gear ratios are switched.
    ● Examples of application: feeder, film splitter, coiler, packaging machinery,printing machinery, embroidery machinery, winding machine and lasercutting machinery.

  • ▶ Full-closed Control Functions

    ● To support external encoder and grating scale (A, B,Z format)
    ● To reduce the impact of mechanical slipping and transmission back clearance and ensure the positioning accuracy of mechanical terminals
    ● Examples of application: CNC machine tools, feeding machine, etc.

  • ▶ Gain Adjustment and Vibration Suppression

    ● Multiple sets of gain selection and gain switching function
    ● Position feed forward and speed feed forward function can significantly reduce tracking error.
    ● Load inertia ratio setting, online identification function and simplified gain adjustment.
    ● The wave trap function eliminates vibration and abnormal noise caused by mechanical resonance.

  • ▶ Electronic Cam

    ● The cam curve data can reach 720 points.
    ● The cubic curve is interpolated by software between two adjacent points,and the number of points does not affect the smoothness of the operation.
    ● To support flying shear, chasing shear and customize curve planning
    ● Easy to use ELESY Soft software to make planning and setting
    ● The driver has the macros for built-in flying shear and chasing shear to directly adjust and re-plan the curve.

  • ▶ Gantry Synchronization

    ● The gantry-type mechanism can be driven by double shaft and the driver can synchronize its position automatically.
    ● When the deviation of synchronized position exceeds the set value, the driver will give an alarm and stop running.
    ● The servo system computer sends pulse commands to two drivers simultaneously.
    ● Via cross connection of position feedback pulse signals from two drivers, the motor running speed is adjusted in real time to synchronize the positions of two shafts.

  • ▶ Built-in motion control function

    ● To provide a 32-segment path for the user to make the planning flexible.
    ● Route types include: zero return, constant speed control, positioning control,modification parameters, and jump path.
    ● Position control support: absolute positioning, relative positioning,incremental positioning, CAP capture positioning.
    ● Multi-stage acceleration /deceleration time, delay time and target speedare optional.
    ● It is convenient to use with the adoption of position control
    ● Multiple trigger modes: software trigger, CNTR signal trigger,EV1/2/3/4 event trigger (jump edge optional).
    ● The graphical setting operation is made via ELESY Soft software and easy for setup.

  • ▶ Communication and field bus functions

    ● With the built-in RS-485 interface, support MODBUS communication protocol.
    ● To support MECHATROLINK- II / III bus communication protocol.
    ● To support CANopen bus communication protocol, support CiA-301,DSP-402 sub-protocol.
    ● To support EtherCAT bus communication and IEC61800-7(CZA402)-CANopenmotion control sub-protocol is adopted for the application layer.
    ● With the corresponding servo system controller,such as CNC numerical control system, PLC, controller, etc., multiple servo drivers can be networked.

  • ▶ ELESY Soft servo control PC software

    ● To support communications with the driver through RS-485 or USB;plug and play, easy to connect.
    ● The parameter editor allows the user to view the modified servo parametersin real time and provide and provide information such as parameter descriptionand setting range; import support and export the user parameter tables, whichcan conveniently configure servo drivers in batches.
    ● The oscilloscope supports 4-channel data acquisition with a refresh rate of 1 kHz,
    ● The user can monitor the servo running waveform, to scale, measure, import, andexport the waveform data.
    ● The IO controller can directly select terminal logic and the function to look at thestatus of the terminals in real time.
    ● Graphical settings is used for motion control and electronic cam function.
    ● Easy to configure and debug related functions.
    ● In addition, it also provides functions such as gain adjustment, parametermonitoring and alarm information.

  • ▶ Energy-saving function (specifications for ES2-021and above )

    ● The driver can share the DC bus and the energy is fully utilizedso that the device is more energy- efficient;
    ● To reduce the quantity of braking resistors,power requirementsand the cost of accessories.
    ● Cases of Application: printing equipment, textile equipmentand unwinder / rewinder
