1. Introduction

Based on customer demand, the FX3U-20SSC-H was developed and introduced to

the world as a high performance, cost effective solution for positioning

applications in the Micro PLC range of factory automation. The unit’s features and

capabilities are very similar to the QD75MH2 positioning module, which was

developed for the Q Series automation platform CPUs.

To setup and program the FX3U-20SSC-H for basic positioning operations, FX

Configurator-FP and GX Developer or GX IEC Developer can be used with a

personal computer. This quick start guide provides an overview of the hardware

and software involved and describes how to set up a system and understand the

device communication. FX Configurator-FP is used for initializing hardware

parameters, setting up positioning tables, and for testing and monitoring the

FX3U-20SSC-H. Please refer to the FX Configurator-FP Operation Manual

(JY997D21801A) for further help.

3. Explanation of System Configuration

3.1 Memory configuration

The F3U-20SSC-H has two types of memory for initial data transfer processes and

continuous communication with servo equipment and programming devices. The

module’s flash memory retains parameter information and table data for initializing servo

equipment at power-ON while the buffer memory (BFM) constantly communicates with

servo equipment and PLC sequence programs. To set up positioning parameters, servo

parameters and table information for the F3U-20SSC-H, it is necessary to send data to

the module from a PLC sequence program or from FX Configurator-FP. Due to the

convenience and reduced complexity of program coding, FX Configurator-FP should be

used whenever possible to program table operations.

Below is a diagram of how the 20SSC-H memory communicates with servo amplifiers,

PLCs and other equipment.

· Control data (The present value change, speed change and operation test command,

etc.)

(4) Read/Write the following data in BFM with sequence program.

· Positioning parameters

· Servo parameters

· Table information

· Monitor data (Operation status, motion status, input signal status, etc.)

· Control data (The present value change, speed change and operation test command,

etc.)

(5) Store the following BFM data to the Flash ROM by the store command from a sequence

program, FX Configurator-FP.

· Positioning parameters

· Servo parameters

· Table information

(6) Positioning/servo parameters and table information transfer from the Flash ROM to the

BFM at power ON. Simultaneously, servo parameters transfer to the servo amplifiers.

(7) Servo parameters in the BFM transfer to the servo amplifiers at power ON.

(8) FX3U-20SSC-H retrieves the servo parameters changed by the servo amplifiers and

updates the servo parameters in its BFM.

In this document, sections of the FX3U-20SSC-H BFM are referred to as:

Positioning parameters

Servo parameters

Table information

Monitor data

Control data

The positioning parameters, servo parameters and table information can be read and

written with several devices including FX Configurator-FP, GX (IEC) Developer and

human machine interfaces. The monitor data can only be read from the BFM (except for

the current address, which has write access), while the control data can be read and

written to the BFM. Control data is written to the BFM very frequently, while positioning

parameters, table information and servo parameters are usually set up less frequently.

For a list of how the areas of the buffer memory can be accessed in terms of read/write,

please refer to the following table.

4. Begin to Use FX3U-20SSC-H with FX Configurator-FP

4.1 Initialization Process

When setting up the F3U-20SSC-H for the first time or when beginning a new project, it is

recommended to clear the servo parameters and positioning parameters and then write

the desired settings (as needed by the user application) to the controller. The purpose of

this section is to define basic settings for the initial testing of the module using the FX

Configurator-FP software.

1) Confirm that the hardware is set up correctly (as described in Section 2.1:

Hardware Requirements) and the PLC is in STOP mode. Turn the power ON.

(Both of the servos should display ‘Ab’ when the power is turned ON for the very

first time.)

2) Open FX Configurator-FP from the Start menu [Start →MELSOFT Application →

FX Configurator-FP] or from the Tools menu of GX Developer [Tools →FX special

function utility →FX Configurator-FP] and create a New file by clicking on in

the Toolbar.

3) Expand the tree of folders in the ‘File data list’ panel on the left-hand side by

double clicking on ‘Unset file,’ ‘Edit’ and ‘Monitor.’

4) Go to [Online →Connection setup →Comm. Test.]

Verify that the devices are communicating properly.

4.1: Initialization Process, the value in BFM# 14028, 14029 (initially zero) is directly

written to the current address. (In stopper type and DOG type mechanical zero return

modes, this method will cause the motor to turn in the direction of the zero point and will

not write zero until the motor comes to a complete stop after detecting an external DOG

signal or stopper device. If the REQ. OPR button causes the motor to rotate

continuously, verify that the Data-set OPR mode has been set in the Positioning

Parameters as described in Section 4.1: Initialization Process.)

Select the Positioning and

Servo parameters to be

written.

Check ‘Flash ROM write’ so

that these settings are active

every time the power is
