Reduced Machine Design and Startup Time

  • The integrated test tool SWM-G Operating Station covers the development processes of SWM-G from design to simulation, contributing to reduction in the total cost of ownership.
  • The network management tool CC-Link IE TSN Configurator enables users to set the network configuration and check the communication status, leading to reduced design time.

Maintenance Solution by MELIPC with SWM-G installed

When SWM-G is installed and operated on the MELIPC (industrial personal computer), the system offers a powerful maintenance solution utilizing the Edgecross-compatible software.

[Predictive/preventive maintenance]

  • The user application collects data of machine diagnosis function, etc. from MR-J5-G through the communication API of SWM-G.
  • The MELIPC analyzes the collected data by using the Edgecross-compatible real-time data analyzer.

[Corrective maintenance]

  • SWM-G collects data from the drive recorder of MR-J5-G through TCP/IP communications, which reduces troubleshooting time.


Installed on a personal computer, SWM-G Motion Control Software can perform motion and network control.

  • Supports a CC-Link IE TSN servo control system with the personal computer where RTX64 (real-time extension) is installed. (RTX64 is included with SWM-G.)
  • Meets various application needs by offering various types of motion control, such as positioning, synchronous, cam, speed, and torque control using API library for motion control.
  • Utilizes network control to connect and set various slave devices (remote I/O modules, etc.) and TCP/IP devices.

Numerous Motion Control Functions

Positioning Control

Continuous path control (path interpolation)

Trajectory control

Helical interpolation

Speed-position switching

Jerk acceleration/deceleration

Jerk acceleration/deceleration

In this method, an axis can be accelerated gradually through adjusting jerk so that the vibrations of the machine can be minimized.
In the example above, the constant positive jerk is applied at the start of the operation to achieve smooth acceleration.
When the axis is shifted to the constant-speed operation, the same amount of negative jerk is applied.
Adjusting jerk in this way achieves smooth acceleration/deceleration while also shortening the time it takes to reach the target speed.
The speed creates a S-curve shape.

Triggered motion

Triggered motion

The triggered motion is a type of command that delays the execution of the motion command until the specified trigger condition is satisfied.
Axes can be started automatically based on the specified conditions by using this command, reducing the cycle time of conveyor systems, etc.
In the operation example above, right after the axis 2 starts execution of normal motion commands, the axis 1 executes the triggered motion command (delaying the execution of the command until the condition is satisfied).
When the condition is satisfied (start trigger ON) during the axis 2 operation, the axis 1 starts executing the motion command.

Synchronous control (tandem drive)

Synchronous control (tandem drive)

Motion Control Software enables tandem operation where the same commands can be outputted to master and slave axes.

Gantry home position return

Gantry home position return

After the master and slave axes pass their respective dogs, the gantry home position return stops both of the axes at the Z-phase of the master axis.
This method enables two or more axes to execute home position return simultaneously, supporting gantry systems.

A Wide Variety of Features

Hot connect (disconnection/reconnection)

The hot connect enables a topology change during operation without requesting a communication stop.
The user application disconnects and reconnects the network through API library.

Monitoring of servo data

The controller obtains the status data of servo amplifiers, such as machine diagnosis information and encoder temperature,
via CC-Link IE TSN. This enables visualization of machine status.

Position synchronous output (cam switch)

The output signal is turned on when a specified condition is satisfied. This function can be used as an alternative to a limit switch.

Touch probe (mark detection)

The current value of the servo motor can be read when the touch probe signal is inputted.
Software and hardware touch probes are available.
Select the touch probe according to your application.

Pitch error compensation

The set offset is applied at regularly spaced command positions. The position error of ball screws can be compensated, improving the operation accuracy.

Backlash compensation

The set offset is applied when the axis changes the travel direction.
The backlash of ball screws can be compensated, which improves operation accuracy of machines.

Acceleration/deceleration methods

The controller offers 24 types of acceleration/deceleration methods, such as trapezoidal, S-curve, jerk ratio, parabolic, sine curve, time acceleration trapezoidal, etc.
Select the method according to your application.

Integrated Test Tool SWM-G Operating Station

This tool provides a variety of features - parameter settings required for application development and the test operation for JOG, inching, and positioning operations. In addition, each axis status and sampled waveforms can be displayed to help user check the start timing and the operation pattern.
