Software Development Environment Q173SCCF

Create a user program by adding the positioning control API library to the project of the C Controller software development environment "CW Workbench". Since the OS for the C Controller (VxWorks®) has been pre-installed, you do not need to install it.

Utility

The utility for C Controller Interface Module/Position Board includes the following software that is necessary for application development.

Utility

Test tool

This tool supports parameter and point data settings for application development, operation check such as servo adjustment and error analysis. MR Configurator2 can be started from the test tool, so servo adjustment is easily performed.

Easy test operation check

Test operation is easily performed by using Positioning test operation functions and Parameter/Point data setting functions.
These functions are useful for checking SSCNETIII/H wiring and motor movement.

Maintenance

You can confirm the sampled waveform of monitor data (32 items) and bit data (16 items) to check the sequence of user programs and startup timing.
Error analysis is carried out with ease by reading the alarm history stored on the non-volatile memory.

Maintenance

API library

The API library is the API functions for creating applications for C Controllers or on a personal computer.
Servo amplifier initialization, parameter change, startup in various operation modes, and monitor, etc. are available.

Device driver

The device driver is software required when a C Controller/a personal computer accesses to the Interface Module/Position Board from a user program via PCI Express<®/PCI bus. You do not have to separately prepare a device driver.

High-speed Synchronous Network SSCNETIII/HQ173SCCFMR-MCseries

  • Communications speed is increased to 150 Mbps full duplex (equivalent to 300 Mbps half duplex), three times faster than the conventional speed.
    System response is dramatically improved.
  • Smooth control of a machine is possible using high-speed serial communications with a cycle time of 0.222 ms.
  • Synchronous communications are achieved with SSCNETIII/H, offering technical advantages for machines that require deterministic control.
  • Long distance wiring is possible up to 3200 m (10498.69 ft.) per system (maximum of 100 m (328.08 ft.) between stations x control axes up to 32 axes), suitable for large-scale systems.
  • SSCNETIII/H compatible and SSCNETIII compatible servo amplifiers can be used together.
    (The communications speed when SSCNETIII compatible products are used together in the same system: 150 Mbps full duplex)

    LJ72MS15 SSCNETIII/H Head Module Q173SCCFMR-MCseries

    The SSCNETIII/H Head module allows the controller to connect remotely with various modules (I/O, analog, high-speed counter, etc.) via SSCNETIII/H.
    These remotely connected modules serve as the controller's remote stations, transmitting the inputs/outputs.
    This results in reduced wiring since the controller receives the I/O and analog I/O signals directly from the servo amplifier side.

  • (Note): MELSOFT GX Works2 is required to set the Head module.

    • (Note-1): Sensor input/output signals for inspection devices, etc. can be read/written via the Head module.
    • (Note-2): Outputs the hand open/close signals.

    Positioning ControlQ173SCCFMR-MCseries

    Positioning operation is performed using the API library in a C language user program.
    The operation is started with positioning data from the point data table and waits until an event occurs by interrupts.

    Positioning Control

    Other Axes Start FunctionQ173SCCFMR-MCseries

    This function automatically starts other axes according to its startup condition and its operation pattern.
    Tact time of assembly machines, etc. is shortened with this automatic startup via controllers.

    Other Axes Start Function

    Pass Position Interrupt FunctionQ173SCCFMR-MCseries

    During automatic operation, interrupts are outputted when axes pass the specified position.
    After that, the corresponding interrupt process of the user program is started.

    • High-speed event processing start on host side (OS) is possible based on the servo axis position
    • A total of 64 points can be specified for pass position data of all axes

    Operation example

    1. 1.As the axes are moving to P2 from P1, the interrupt occurs.
    2. 2.The vision camera takes photos of the workpiece according to the interrupts.
    3. 3.The position data is read.
      The vision camera takes photo responding to the interrupts.
      Thus by taking photos periodically with interrupts, more accurate position data is available.
    Pass Position Interrupt Function

    Tightening & Press-fit ControlQ173SCCFMR-MCseries

    The motor can be switched to torque control (tightening & press-fit mode) during positioning without stopping.
    Since the current position is controlled even during the tightening & press-fit control, positioning operation based on the absolute position coordinates can be performed smoothly after switching back to positioning control.

    Tightening & Press-fit Control

    Interface Mode FunctionQ173SCCF MR-MCseries

    This standard feature realizes unique control based on a C-language user program using SSCNETIII/H

    The interface mode function transmits the position commands received from a user program to servo amplifiers every operation cycle. This allows servo amplifier to be controlled using a user program.
    Speed and torque controls are also available in this method.
    So, a MR-J4-B can be controlled based on user programs created with your programming know-how of position/speed/torque commands while taking advantage of SSCNETIII/H servo system synchronous network performance.

    • The C Controller Interface Module or Position Board controls the SSCNETIII/H processing. This allows the user-program side to focus on information processing, human machine interface, and Motion control.
    • A personal computer with a real-time OS can perform fixed-cycle Motion control using interrupts at every operation cycle.
    • Thanks to the position command buffers of up to 64 phases, even non-real-time OS (Windows® only) can perform at 0.22 ms (the fastest rate) cycle command operation; This enables further increase in accuracy in trajectory control.
