Operation Overview
In communication with the Mitsubishi servo system controller, the inverter operation (speed control or
position control or torque control under vector control with encoder) or monitoring can be performed from a
program on the servo system controller.
Application of optical communication method greatly improved the communication speed and noise
resistance of the SSCNET ΙΙΙ as compared with the conventional SSCNET. In addition, 50m of the
maximum wiring length between stations is realized.

PRE-OPERATION INSTRUCTIONS
CAUTION
y Mounting both the FR-A7NS and FR-A7AP/FR-A7AL and performing vector control enables SSCNET ΙΙΙ
communication.
When operating the inverter with the FR-A7NS mounted and without FR-A7AP/FR-A7AL, option alarm
(E.OPT) occurs. (Refer to page 77.) Also option alarm (E.OPT) occurs when the FR-A7AP and FR-A7NS are not
connected with the FR-A7AP connection cable (the FR-A7AL and FR-A7NS are not connected with the FRA7NS connection cable) during a stop of the inverter. (Refer to page 77.) (In those conditions, however, option
fault (E.OPT) does not occur when Pr.800 Control method selection = "9" (vector control test operation) (refer to
page 49) or when Pr.499 SSCNET III operation selection = "9999" (operation invalid). (refer to page 42))
y An alarm such as overcurrent shut off (E.OC3) and position error large (E.OD) may occur depending on the
status of the motor current and droop pulses during inverter operation.

WIRING
3.3.1
SSCNET III cable laying
SSCNET ΙΙΙ cable is made of optical fiber. Application of a power, such as a major shock, lateral pressure,
haul, and abrupt bending or twisting, to the optical fiber will deform or break the inside, disabling optical
transmission. Especially, the optical fibers of the MR-J3BUS…M, MR-J3BUS…M-A which is made of
synthetic resin will melt down if exposed to fire and high temperature. Therefore, avoid the cable from
contacting with the hot section such as heatsink of the inverter and an option for regeneration.
Read described item of this subsection carefully and handle it with caution.
(1) Minimum bend radius
Make sure to lay the cable with greater radius than the minimum bend radius. Do not press the cable to
edges of equipment or others. For SSCNET ΙΙΙ cable, the appropriate length should be selected with due
consideration for the dimensions and arrangement of inverter. Ensure that the cable bend will not become
smaller than the minimum bend radius if the SSCNET ΙΙΙ cable is pressed down when the door of the
enclosure is closed.
For the minimum bend radius, refer to page 21.
(2) Bundle fixing
Use the accessory cable tie to bundle the SSCNET ΙΙΙ cable outside the inverter, and fix the bundled cable
to the installation surface of the inverter. Fix the SSCNET ΙΙΙ cable using a cable tie by gently slackening
the optical code with keeping a larger radius than the minimum bend radius, and it should not be twisted.
(Refer to page 31.) When binding the cable with a cable tie other than the provided one, use a cushioning
material such as plasticizer-free sponge and rubber to fix it.
Never use vinyl tape for cord. Plasticizing material in vinyl tape goes into optical fiber and lowers the optical
characteristic. At worst, it may cause wire breakage. If using adhesive tape for cable laying, the fire
resistant acetate cloth adhesive tape 570F (Teraoka Seisakusho Co., Ltd) is recommended.
If laying with other wires, do not make the cable touched wires or cables made from soft polyvinyl chloride
(PVC), polyethylene resin (PE), Fluorocarbon resin or nylon which contains plasticizing material.
24
WIRING
(3) Tension
Applied tension to fiber optics causes external force to concentrate in the section where fiber optics are
fixed and an optical connector is connected, increasing transmission loss. If a larger pressure is further
applied, this could cause a disconnection of optical fibers and a damage to the optical connector. For cable
laying, handle without putting forced tension. For the tension strength, refer to page 21.
(4) Lateral pressure
Applying a lateral pressure to the fiber cable deforms the cable itself and applies pressure to the internal
fiber, resulting in increase in transmission loss. Moreover, if a larger pressure is further applied, the optical
cable may be disconnected in the worst case. As the same condition also occurs at cable laying, do not
tighten up optical cable with a thing such as nylon band (TY-RAP).
Do not trample it down or tuck it down with the door of enclosure or others.
(5) Twisting
If optical fiber is twisted, it will become the same stress added condition as when local lateral pressure or
bend is added. This could increase a transmission loss. Moreover, if a larger pressure is further applied,
the optical cable may be disconnected in the worst case.

Description
As offline auto tuning is performed with the inverter alone, the
inverter does not follow commands from the SSCNET ΙΙΙ
communication. (Perform tuning before operation using SSCNET ΙΙΙ
communication.)
Since SSCNET ΙΙΙ communication operation uses only the first motor,
the second and third functions are made invalid. (Note that only the
second and third output frequency detection are valid.)
Functions related to position control irrelevant to SSCNET ΙΙΙ, such
as parameter position control and position command selection, are
invalid.
As speed, position, and torque control can be switched by the
communication data of SSCNET ΙΙΙ, control method selection is
invalid. As the inverter follows the command given from the servo
system controller side during SSCNET ΙΙΙ operation, torque
command is invalid.
SSCNET ΙΙΙ operation mode set at powering on the inverter (mode
can not be changed to other operation mode). When initialized

FU2, FU3: Output when the inverter output
frequency exceeds detected specification frequency.
The signal is on even when the servo is off during
SSCNET ΙΙΙ communication operation.

PRECAUTIONS
y During SSCNET ΙΙΙ communication, the inverter parameter can not be changed from the servo system
controller. Note that, even if the mode has changed to SSCNET ΙΙΙ operation mode, setting “2” in Pr.77
Parameter write selection allows parameter setting change from the PU (FR-DU07/FR-PU07/FR-PU04).
In such case, Pr.CL Parameter clear and ALLC All parameter clear can not be made.
y The usable encoder pulses are 1000 to 4096 pulses.
y Start and stop commands are given from SSCNET ΙΙΙ side and STF signal and STR signal are made
invalid. Instead, upper stroke limit signal can be assigned to STF terminal and lower stroke limit signal to
STR terminal. (Refer to page 69 for input terminal function validity/invalidity.)
y Before starting operation, always give the servo ON signal from the host controller to put the motor in the
servo lock status, and then start operation.
y Running speed depends on the command from the servo system controller.
(The rotation direction depends on the setting of Pr. 379 SSCNET III rotation direction selection.)
y When "0, 10" (droop control is disabled during acceleration/deceleration) is set in Pr.288 Droop function
activation selection, droop control can not be performed. Set "1, 11" or "2".
(For details, refer to the inverter manual.)
y E.OC3 and E.OV3 are displayed when the inverter stops due to "overcurrent shut-off" or "regenerative
overvoltage shut-off" during SSCNET ΙΙΙ operation. (For details, refer to the inverter manual.)
y Restrictions of I/O signal (Refer to page 69) are the same even when used with other options (FR-A7AX,
FR-A7AY, FR-A7AR, etc).
y Offline auto tuning cannot be performed from the servo system controller. Perform it using the PU or the
setup software (FR Configurator FR-SW3-SETUP-WE) before starting communication.
y Before shutting off the communication temporarily by resetting the inverter power, disconnecting the
SSCNET III cable, or other methods, it is necessary to perform the disconnection/reconnection function
for the servo system controller. Refer to "Q173DCPU/Q172DCPU motion controller programming manual
(common mode version)" for details.
y When the MRS signal is on, create a motion SFC program that turns on the servo off command of the
target shaft. Before resetting the MRS signal (ON to OFF) or turning off the servo off command, make sure
that the motor speed is 20r/min or less.
