Features
Combined with a CC-Link IE TSN-compatible servo amplifier, the Motion module offers a high-performance servo system that improves machine capability.
- Performs advanced motion control, such as positioning, synchronous, cam, and speed-torque control.
- Connects remote I/O modules and FR-A800-GN inverters via CC-Link IE TSN. The data of these devices can be read/written by a CPU module.
- Connects TCP/IP devices, enabling a flexible system configuration.
- Possible to reuse the existing projects of the MELSEC iQ-F series Simple Motion modules (previous model).
The Motion module enables advanced motion control while offering cost-effectiveness.
The module has the capability and functions required for stand-alone/small-scale systems.

FX5-80SSC-G
- Maximum number of control axes:
4 axes/module (FX5-40SSC-G), 8 axes/module (FX5-80SSC-G)
- Minimum operation cycle*1: 500 [μs]
- Maximum number of connected modules*2: 4 modules/system
- *1. The operation cycle varies by the number of control axes and the models.
- *2. This refers to the total number of the Motion modules and one FX5-CCLGN-MS (master station).
Heritage (Reuse of Existing Projects)
The existing projects of the MELSEC iQ-F series Simple Motion module (previous model) can be reused. This enables reduction in program development time.
- * Parameter settings for the network and servo amplifiers are required.
Positioning Control
The Motion module executes various positioning control, such as trajectory control that combines linear and circular interpolation and speed-position switching.
Linear interpolation
Circular interpolation
Trajectory control
Speed-position switching
Programming
The Motion module easily executes positioning operation with the instruction in a sequence program that starts a positioning data of the motion profile table. To meet various application needs, the Motion module offers various types of control, such as linear/two-axis circular interpolation, fixed-pitch feed, and trajectory control.
Synchronous Control
Synchronous control can be achieved using software instead of controlling mechanically with gear, shaft, clutch, speed change gear or cam, etc.
- Synchronous control can be flexibly started/ended for each axis, enabling the synchronous control axis and positioning control axis to be used within the same program.
- Command generation axis, servo input axis, or synchronous encoder axis can be set as the input axis.
- The output axis is operated with a cam. The following three operations can be performed with the cam functions: linear operation, two-way operation, and feed operation.
- An incremental synchronous encoder*1 can be connected via MR-J5-G(-RJ)/MR-J5W2-G servo amplifier.
- *1. When configuring an absolute position system, use an encoder of HK series servo motors.
Parameter Settings
Synchronous control is executed by setting parameters of the input axis, output axis, gear, and clutch for synchronous control and turning on the synchronous control start signal.
The cam graph can be flexibly and easily created through drag & drop. The waveform is changed according to the pointer’s movement.
Start/Stop
Synchronous control can be executed after synchronous parameters are set for each output axis. When synchronous control start signal is turned on, the synchronous control parameters are analyzed, and the status is changed to during synchronous control.
The output axis is operated by the commands transmitted from the input axis.
Speed-Torque Control
Speed Control/Torque Control
The axes in speed control are controlled to run at the constant speed following the speed command, and the axes in torque control are at the constant torque following the torque command.
The Motion module can be used for tension control application, such as unwinding or rewinding.
In addition, the current positions are always tracked even in speed and torque control, and therefore positioning is executed smoothly in accordance with the absolute position coordinate in position control after switched from the speed and torque control.
Continuous Operation to Torque Control
When using this control, you can switch from position control to torque control continuously without stopping the servo motor.
- The current positions are always tracked even in torque control, and therefore positioning is executed smoothly in position control after switched from the torque control.
- Position control is smoothly switched to torque control without stopping the servo motor.
[An example of continuous operation to torque control]
This control is applicable to a variety of machines, such as bonding, press-fit, punching, and clamping machines.
Auxiliary Features
Virtual Servo Amplifier
The virtual servo amplifier function enables operations of a virtual servo amplifier as if an actual unit is connected.
When the virtual servo amplifier is set as a servo input axis of synchronous control, the Motion module executes synchronous control with virtually generated input commands.
In addition, this function is used to simulate an axis without an actual connection.
Automatic Return
When slave stations are back to normal status after disconnected due to a data link error, this function automatically returns the disconnected stations to the network and restarts data link.
When defective components need to be replaced in one of the machines in a production line or one of the units in a machine, only the machine or the unit can be partly turned off without powering off the whole system.
Batteryless Operation
The Motion module and the servo amplifier can be operated without a battery.*1
Maintenance costs are reduced as a result of eliminating the battery replacement and stock control.
- *1. Direct drive motors may require a battery.
Mark Detection
This function latches data responding to a trigger signal input to a servo amplifier.
The compensation amount is calculated based on the latched data, and the error is compensated using a compensation axis.
