1 Introduction The servo amplifiers of the MR-J3-T series are designed specifically for drive positioning appli - cations using point-to-point positioning without interpolation or trajectory control .
Required for positioning contr ol via a CC-Link network: 쎲 Q-Rack with PLC and the CC-Link module QJ61BT11N or A–Rack with PLC and CC-Link module A1SJ61BT11, A1SJ61QBT11 or FX2N-16CCL-M 쎲 CC-Link cable compatib le with version V 1.
2 Installing the Equipment The procedure for the physical installation of the MR-J3-T series hardware is exactly the same as for the MR-J3-A and MR-J3-B models. The dimensions of the MR-J3-T series amplifiers are identical to those of the matching models of the MR-J3-A and MR-J3-B series.

3 . 2 Functional T est Settings The following input signals are required to activate the servo amplifier’s motor output: 쎲 EMG -> F orce stop (saf ety signal) 쎲 SON -> Ser v o ON 쎲 LSP -.
– Set the parameter f or the automatic activation of the EMG, SON and LSP/LSN input signals: P arameter PD01 “Input signal automatic ON selection 1” = 1C04 – T ur n the ser vo amplifier off and then tur n it on again to initialise the new parameter set - ting.
3 . 3 Configuring P ositioning P oint T ables The position values, travel speeds and acceleration and deceleration times are stored in tables known as “point tables”. We will now go through the steps required to configure and define a point table.
3 . 4 Functional T est with MR Configurator Using MR Configurator you can perform a basic test of the individual positioning steps and make adjustments for your application. Note that setting parameter PA14 does not have any effect on the rotation direction in jog mode when using MR Configurator.
4 Positioning with Digital Inputs This chapter describes how point table positioning is used in most applications with the MR-J3-T series amplifiers and the MR-J3-D01 I/O extension.

Examples: 햲 The Z-phase of the encoder is defined as the physical home position of the machine. In this e xample we are going to perf or m the home position retur n at 200 r pm in the direction in which the encoder pulses are counted incrementally .

4 . 3 . 2 Dog mode home position return In this mode, instead of the encoder Z-phase(Fig. 4-6), the DOG signal is used to switch from “home position return speed” PC04 to “creep speed” PC05 .

Parameter settings: The position value is calculated as follows: X = PA05 폷 PC07 in [mm] In the above example with PA05 = 1 and PC07 = 1000 [10 STM µm] this gives us: X = 1000 폷 10 1 µm Home Position Return Positioning with Digital Inputs 4-2 2 MITSUBISHI ELECTRIC Fig.
4 . 4 Configuration f or P ositioning If you install the MR-J3-D01 I/O expansion you can use point table positioning, which allows you to select positions from a list of up to 256 table entries with a combination of eight digital inputs. Table 4-3 shows how binary input signals are encoded to address the point table entries.
The following example shows some typical configuration settings used for many common posi - tioning applications: Procedure: 햲 Select the incremental system f or positions with P A03 *ABS . 햳 Select absolute v alue command mode f or target positions with PA 0 1 * S T Y .
햵 The point table entries f or the individual pos itioning steps are configured in the columns numbered to in the point tab le list sho wn below . Tips for editing point tabl e entries: 쎲 The value in the A ux. Func. column should nor mally alwa ys be zero .
쎲 Alwa ys deactivate star t command ST1/ST2 bef ore s tar ting a new positioning sequence. Then you can select a ne w table entry with DI0 - DI7 and star t the positioning sequence with ST1/ST2.

4 . 5 Functional T est of Digital Input P ositioning Normally you need a simple controller to set the digital inputs used to select the point table posi - tion entries, for example a PC, a mini PLC or an HMI control terminal.
MR Configurator can monitor all the inputs and outputs of the MR-J3-T, including those on the MR-J3-D01 I/O extension. Procedure: 햲 Connect the PC/notebook to the USB por t (CN5) of the ser v o amplifier using cable MR-J3USBCBL3M. 햳 Star t MR Configurator and make the f ollowing selections: – Select the MR-J3-T series amplifier.

5 Positioning via a CC-Link Network As an alternative to using digital signals you can also control positioning with MR-J3-T servo amplifiers via a CC-Link network connection. NO TE Before proceeding ensure that the MR-J3-D01I/O e xpansion card is not installed.
Connections for the CC-Link network NO TE Y ou must install a terminating resistor on ter minals DB and DB on the ph ysical first and last stations in the CC-Link network. The required ohmage of the resistor depends on the cable length, please check the v ersion V1.
5 . 2 CC-Link Comm unication Settings 5 . 2 . 1 Settings on the serv o amplifier In the instructions below we are assuming that you have an operating CC-Link network with the following specifications: 쎲 Data rate 156Kbit/s 쎲 The master station is a QJ61BT11N module that is integrated in a System Q con - troller platf or m with a Q02H-CPU .
햴 Set the data rate: NO TE The ser vo amplifier settings required f or point table positioning are descr ibed in chapters 4.2 through 4.4. Please check that these settings hav e been made correctly before proceeding. CC-Link Communication Settings Posit ion ing via a CC-L ink Netwo rk 5-3 4 MITSUBISHI ELECTRIC Fig.
5 . 2 . 2 Configuration f or communication with GX IEC De veloper Generally, positioning control is performed via a CC-Link network in applications where an addi - tional PLC system is used for automation tasks as well as the integrated controller in the ampli - fier.
Notes on the network settings: (a) In the example only one servo amplifier is connected to the CC-Link network. This value must be increased by the number of slave stations installed if applicable. (b) These values specify which bits or data words are to be used to control the servo amplifier.
5 . 3 T esting the Serv o Amplifier via CC-Link Before proceeding it is a good idea use the monitoring function in GX IEX Developer to check that the individual servo functions can be started correctly (e.g. return to home, positioning). After this you can then test the correct operation of the servo system with the PLC program.
