1.1 Functions and configuration
Establishing and disconnecting the communication
Establishing the communication
Configure the system and set the parameters or rotary switches that are required for startup of the CC-Link IE TSN master
station and the servo amplifier. The communication will be established if the settings of the master station and the servo
amplifiers are made correctly. When the communication is established, the 7-segment LED display of the servo amplifiers
changes to "controller is connected".
Disconnecting the communication
■Procedure for disconnecting the communication
When shutting off the system power or disconnecting the servo amplifier from the network, be sure to disconnect after servo-
off. Failing to do so may trigger [AL. 086].
■Changing the communication configuration
Make sure that the servo amplifier is in servo-off state before changing the network configuration. Failing to do so may trigger
[AL. 086].
Summary of object dictionary (OD)
The data that a device holds, such as control parameters, command values, and feedback values, is handled as an object
composed of an Index, object name, object type, R/W attribute, and other elements. The data is exchanged between the
master and slave devices. The aggregate of these objects is called an object dictionary (OD).
Section definition of object dictionary
The following shows the structure of an object dictionary.
The classification of the objects defined by Mitsubishi Electric is as follows.

Saving object dictionary data
Some of object dictionary data is stored in a non-volatile memory and some is not. Use [Store parameters (Obj. 1010h)] for
storing the object dictionary data in the non-volatile memory.
For details about objects that can be stored in the non-volatile memory, refer to the following.
MR-JET-G User's Manual (Object Dictionary)
■Store parameters
Writing "65766173h" (= reverse order of the ASCII code "save") to [Store parameters (Obj. 1010h: 01h)] enables the setting
value of an object to be stored in the non-volatile memory of the servo amplifier.
It can take up to around 25 s for [Save all parameters (Obj. 1010h: 01h)] to write all the parameters. Do not shut off the power
supply during writing.
Reading [Save all parameters (Obj. 1010h: 01h)] will produce the following values. Bit 0 is "0" during saving and "1" when not
saving.
Precautions
To shut off the power supply after executing Store parameters, make sure that a save is not in progress (Bit 0 is on), then shut
off the power.
■Restore default parameters
Objects can be reset to the factory setting.
To initialize objects, write "64616F6Ch" (= reverse order of the ASCII code "load") to [Restore all default parameters (Obj.
1011h: 01h)], then cycle the power. Writing a value other than "load" (= 64616F6Ch) triggers an error. Initialization can take up
to around 25 s.
Reading [Restore all default parameters (Obj. 1011h: 01h)] will display "00000001h" (command valid).

MR Configurator2 This is a software that has the following functions: servo amplifier adjustment, monitor display, diagnosis,
reading/writing of servo parameters, and test operation. These functions are performed using a personal
computer.
Settings, such as a stroke limit, absolute position detection system, communication error detection time, are
made with this software.
If using MR Configurator2 via a network, start MR Configurator2 from GX Works3. The servo amplifier and the
personal computer do not need to be connected with a USB cable because they communicate each other via the
controller.
GX Works3 This is a software that comprehensively supports the design and maintenance of the programmable controllers.
The software performs settings such as servo amplifier profile (CSP+) registration, network configuration setting
(station specific mode, link device setting, etc.), refresh setting, and network synchronization setting.

amplifier. When there is a difference in those parameters, the parameters held by the CPU module are automatically written to
the replaced servo amplifier.
Storage method of parameters
There are following two ways to store parameters in the master station.
• If data in the non-volatile memory of the servo amplifier are rewritten by the engineering tool, the parameters in the CPU
module are also updated automatically.
• If differences from the previously stored parameters are found in a periodical check, the parameters in the CPU module are
also updated automatically (Set an interval in [Pr. PN20 Parameter automatic backup update interval] for that periodical
check).
Parameters that can be stored
The parameters that can be written on the servo amplifier and stored with this function are as follows.
• Servo parameter
• Network parameters
Precautions
• When the parameter that requires power cycling after being set is changed by the parameter automatic setting, [AL. 09E.7
Parameter unreflected warning] occurs. Cycle the power of the servo amplifier.
• Do not turn off the power supply of the controller during backup. Before turning off the power supply of the controller, check
the rewrite-status of the parameter file of the slave station by using the event history function of the controller.
• Parameters that are automatically updated by the servo amplifier, such as auto tuning data, may not match the data stored
in the slave station parameter file on the controller. To match the data, first read the servo amplifier parameters using MR
Configurator2 or other engineering tools, then reflect the readings on the slave station parameter file on "Detail Setting" in
"Parameter Automatic Setting" of GX Works3 before writing the readings to the controller again. Or, set [Pr. PN20
Parameter automatic backup update interval] so that the data can be backed up in the master station periodically.
• If performing automatic backup with the interval set in [Pr. PN20], use a master station which features power interruption
protection. Failing to do so triggers [AL. 19E.1 Parameter automatic backup setting warning]. At this time, the automatic
backup is disabled.

Hold/Clear of output at CPU STOP and at CPU stop error
This function sets Hold/Clear of the auto refresh device output when CPU module operation of the cyclic master is at STOP or
at CPU stop error.
The following shows the servo amplifier status at CPU STOP and at stop error.
Motion mode
■Motion control axis
The servo amplifier stops the servo motor in the manner commanded by the controller.
■Motion non-control axis
The servo amplifier decelerates the servo motor to a stop.
Remote reset
Resetting can be done by sending the reset command to the specified station. The reset command can be sent from the
Remote Operation window of GX Works3.
Refer to the following for details.
Page 12 Remote Operation
Clock function
This function is used to acquire time information from the grand master (the station serving as a clock source) via CC-Link IE
TSN so that this information may be used for the time management of functions performed by the servo amplifier, such as
alarm history. The time synchronization protocol for the grand master and the servo amplifier uses IEEE1588 or
IEEE802.1AS.

CC-Link IE TSN communication protocol
Communication management
The communication state of the slave unit in CC-Link IE TSN is broadly classified as being either an "initialization phase" or an
"under control communication phase" and then managed.
■Communication state management of the motion mode
The motion mode of the servo amplifier support CANopen profile.
For devices that support the CANopen profile, the communication state of CC-Link IE TSN is managed by the Network
Management (NMT) state machine.
• Communication state
The NMT state machine manages the four states shown below (Init, Pre-Operational, Safe-Operational, and Operational).
The communication state transitions in each slave station.
State Main processing details
Init Operates in accordance with the procedures performed in "initialization phase" of CC-Link IE TSN, such as
management master mediation, connection structure detection, propagation delay measurement, communication
band setting. The servo motor cannot be operated.
Pre-Operational The master station (the Motion module) and the slave station (the servo amplifier) send and receive SDOs with
transient transmission, and get ready to start or to resume operation by setting the control mode and PDO mappings
as well as performing other preparations. The servo motor cannot be operated. Refer to the following for transient
transmission.
Page 25 Transient transmission
Safe-Operational The master station (the Motion module) and the slave station (the servo amplifier) send and receive PDOs with cyclic
transmission. The servo motor cannot be operated. Refer to the following for cyclic transmission.
Page 18 Cyclic transmission
Operational The master station (the Motion module) and the slave station (the servo amplifier) send and receive PDOs with cyclic
transmission. The servo motor can be operated.

The state transition diagram of the NMT state machine is as follows.
The servo amplifier transitions the communication state by receiving the SLMP command (NMT State Download) from the
master station or by other means.
The controller and the servo amplifier perform the following procedure to establish communication (transition to
"Operational").
■SLMP command
The SLMP commands used in communication state management are as follows.
Transition No. Operation

(2) During the transition from the initialization phase to the control communication phase of CC-Link IE TSN, the servo amplifier transitions
from "Init" to "Pre-Operational".
(3) When the master station issues NMT State Download (SLMP) for "Init" to the servo amplifier, or when a communication time-out occurs,
the servo amplifier transitions from "Pre-Operational" to "Init".

Cyclic transmission
Cyclic transmission is a function that cyclically exchanges data between stations.
Cyclic transmission of motion mode
Cyclic transmission of the motion mode is a function that uses PDOs to cyclically exchange data between stations.
A PDO is an aggregate of objects such as [Modes of operation (Obj. 6060h)] and [Modes of operation display (Obj. 6061h)].
The placement of objects in a PDO is called PDO mapping, and the initial placement (default PDO mapping) is defined. The
PDO received by each station is called an RPDO, and the PDO transmitted by each station is called a TPDO.
PDOs are transferred using the cyclic Ms frame (from the master station to the slave station) and the cyclic Ss frame (from the
slave station to the master station).
A conceptual figure of communication between the master station and the slave station is shown below.
