Incorrect handling may cause hazardous conditions, resulting in medium or slight injury, or may cause only material
damage.
level may even lead to a serious consequence according to conditions. Both instruction levels must be followed
because these are important to personal safety.
 Electric shock prevention
Warning
 While the inverter power is ON, do not open the front cover or the wiring cover. Do not run the inverter with the front cover or the wiring cover removed. Otherwise
you may access the exposed high voltage terminals or the charging part of the circuitry and get an electric shock.
 Do not remove the inverter front cover even if the power supply is disconnected. The only exception for this would be when performing wiring and periodic
inspection. You may accidentally touch the charged inverter circuits and get an electric shock.
 Before wiring or inspection, LED indication of the inverter unit operation panel must be switched OFF. Any person who is involved in wiring or inspection shall wait
for at least 10 minutes after the power supply has been switched OFF and check that there is no residual voltage using a tester or the like. For some time after the
power-OFF, a high voltage remains in the smoothing capacitor, and it is dangerous.
 Any person who is involved in wiring or inspection of this equipment shall be fully competent to do the work.
 The plug-in option must be installed before wiring. Otherwise you may get an electric shock or be injured.
 Do not touch the plug-in option or handle the cables with wet hands. Otherwise you may get an electric shock.
 Do not subject the cables to scratches, excessive stress, heavy loads or pinching. Otherwise you may get an electric shock.
 Injury prevention
Caution




The voltage applied to each terminal must be the ones specified in the Instruction Manual. Otherwise a burst, damage, etc. may occur.
The cables must be connected to the correct terminals. Otherwise a burst, damage, etc. may occur.
The polarity (+ and -) must be correct. Otherwise a burst or damage may occur.
While power is ON or for some time after power OFF, do not touch the inverter as it will be extremely hot. Touching these devices may cause a burn.

NOTE
• Installing both the FR-A8NS and FR-A8AP/FR-A8AL enables vector control and SSCNET III(/H) communication.
When the FR-A8NS is installed but the FR-A8AP/FR-A8AL, option fault (E.OPT) occurs. Also an option fault (E.OPT)
occurs when the FR-A8AP/FR-A8AL connection cable is not connected between the FR-A8NS and the FR-A8AP or
FR-A8AL. (Refer to page 75.)
(If the FR-A8AP/FR-A8AL connection cable is accidentally detached during inverter operation, the alarms such as
overcurrent trip (E.OC3) and excessive position fault (E.OD) may occur depending on the status of the motor current
and droop pulses.)

Instructions for laying the SSCNET III cable
SSCNET III cable is made of optical fiber. Application of a power such as a major shock, abrupt bending, haul, lateral pressure,
or torsion to the fiber-optic cable will deform or break the inside, disabling optical transmission.
Read described item of this subsection carefully and handle it with caution.
In addition, the optical fiber of the MR-J3BUS[]M and the MR-J3BUS[]M-A may melt if they are exposed to fire or high
temperature, as they are made of synthetic resin. Therefore, prevent the cable from contacting with the hot sections such as
heatsinks of the inverter or regenerative options.
 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 the SSCNET III cable, the appropriate length should be selected with due consideration for the dimensions and
arrangement of the inverter. Ensure that the cable bend will not become smaller than the minimum bend radius if the SSCNET
III cable is pressed down when the door of the enclosure is closed. For the minimum bend radius, refer to page 22.
3
 Bundle fixing
When fixing the SSCNET III cable using cable ties, keep a bend in the cord part of the fiber-optic cable slightly curved so that a
radius of curvature of the cord stays larger than the minimum permissible radius, and keep the cord from being twisted.
In binding the cord with a cable tie, use a cushioning material such as plasticizer-free sponge or rubber, and fasten the cord
tight.
Never use vinyl tape for the cord. Plasticizing material in vinyl tape may go into optical fiber and degrade the optical
characteristic, which causes wire breakage. If using adhesive tape for binding cables, the flame-retardant acetate cloth
adhesive tape 570F (Teraoka Seisakusho Co., Ltd.) is recommended.
If laying the cable together with other wires, keep the cable away from the wires or cables made from soft polyvinyl chloride
(PVC), polyethylene resin (PE), fluorocarbon resin or nylon which contains plasticizing material.
 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 disconnection of
optical fibers and damage to the optical connector. For cable laying, handle without putting forced tension. For the tension
strength, refer to page 22.
WIRING
25
 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. If a larger pressure is further applied, the cable may be disconnected. 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.
 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. If a larger pressure is further applied, the cable may be disconnected.
Keep the SSCNET III cable from being twisted during laying operations.
 Dust
If the end face of cord tip for the SSCNET III cable is dirty, optical transmission is interrupted and it may cause malfunctions. If
it becomes dirty, wipe with a bonded textile, etc. Do not use solvent such as alcohol.
 Disposal
When incinerating optical cable (cord) used for SSCNET III cable, hydrogen fluoride gas or hydrogen chloride gas which is
corrosive and harmful may be generated. For disposal of SSCNET III cable, request for specialized industrial waste disposal
services who has incineration facility for disposing hydrogen fluoride gas or hydrogen chloride gas.
NOTE
• Do not look directly into the light beam emitted from SSCNET III fiber-optic cable. Doing so may cause eye discomfort.
(The light source of SSCNET III(/H) cable complies with class1 defined in JISC6802 or IEC60825-1.)

NOTE
• For the final axis, do not remove the connector cap of the SSCNET III cable connector (CN1B).
• When wiring cables to the inverter's RS-485 terminals with a plug-in option mounted, take caution not to let the cables
touch the circuit board of the option or of the inverter. Otherwise, electromagnetic noises may cause malfunctions.
Caution

After wiring, wire offcuts must not be left in the inverter. Wire offcuts can cause an alarm, failure or malfunction.

SSCNET III(/H) COMMUNICATION STATUS
When the inverter is powered ON while Pr.499 SSCNET III(/H) operation selection is set to a value other than "9999" and the
X85 signal is turned OFF, the inverter is ready to start the SSCNET III(/H) initial data communication (initialized
communication). As the inverter is set in the SSCNET III(/H) operation mode as soon as it is in the state, the operation mode
cannot be switched to the External operation mode or the PU operation mode. Also, the following settings are disabled: Pr.79
Operation mode selection, Pr.338 Communication operation command source, Pr.339 Communication speed
command source, Pr.340 Communication startup mode selection, and Pr.550 NET mode operation command source
selection.
The SSCNET III(/H) communication status with the servo system controller can be monitored. (Refer to page 28.)
For the state transition of the inverter during the SSCNET III(/H) communication, refer to page 29.
For the details of the SSCNET III(/H) communication status, refer to page 31.

Input terminal function selection
• To use home position return with proximity dog (to input the DOG signal to the servo system controller via an inverter input
terminal) in SSCNET III(/H) communication, set "76" (for the X76 signal and proximity dog) in any of Pr.178 to Pr.189 (input
terminal function selection).
• To input the FLS or RLS signal to the servo system controller via an inverter input terminal, set "88" (for the LSP signal,
upper stroke limit) or "89" (for the LSN signal, lower stroke limit) in any of Pr.178 to Pr.189 (input terminal function
selection). (Though the FLS or RLS signal can be input to the servo system controller similarly with the STF signal (when
"60" (initial value) is set in Pr.178 STF terminal function selection) or the STR signal (when "61" (initial value) is set in
Pr.179 STR terminal function selection), the LSP or LSN signal has a higher priority than the STF or STR signal.)

Reset the inverter after the Pr.800 setting is switched between "9" and any of other than "9". The setting is applied after an inverter reset.
When "9" is set in Pr. 800, test operation is enabled without motor.
When "9" (vector control test operation) is set in Pr. 800, it is recommended to set "0" in Pr. 880 Load inertia ratio.
For the details of Pr.880, refer to the Instruction Manual (Detailed) of the inverter.
Setting Pr.800 = "100 or higher" does not select the fast-response operation. (Normal-response operation is applied during vector
control.)

Function
Available only for standard models.
Available when the plug-in option or control terminal option is installed.
Available only for standard models and IP55 compatible models.
The RUN or RUN2 signal turns ON when speed command from SSCNET III(/H) is not 0 Hz in a state of servo-ON during speed control or
torque control. The signal turns ON when the servo is ON during position control.
The signal turns ON even when the servo is OFF during SSCNET III(/H) communication operation.
RESTRICTIONS ON THE FUNCTIONS

PRECAUTIONS
• During SSCNET III(/H) communication, the inverter parameter can not be changed with the servo system controller. When
Pr.77 Parameter write selection = "2", the parameter settings can be changed on the PU even if the inverter is set in the
SSCNET III(/H) operation mode.
• Available range of encoder pulses is 1000 to 4096 pulses.
• The valid command for an inverter start or stop is given via the SSCNET III(/H) communication. Though the STF and STR
signals are invalid, the STF signal is used as the upper stroke limit signal and the STF signal as the lower stroke limit signal.
(Refer to page 67 for input terminal function validity/invalidity.)
• Before starting operation, always give the servo-ON signal from the host controller to the motor in order to set the motor in
the servo lock state.
• Running speed depends on the command from the servo system controller. (The rotation direction depends on the setting of
Pr.379 SSCNET III(/H) rotation direction selection.)
• When "0 or 10" (droop control is disabled during acceleration/deceleration) is set in Pr.288 Droop function activation
selection, droop control can not be performed. Set a value other than "0 or 10" in Pr.288. (For the details, refer to the
Instruction Manual (Detailed) of the inverter.)
• The fault indication "E.OC3" or "E.OV3" is displayed when the inverter stops due to an overcurrent trip or overvoltage trip
during SSCNET III(/H) operation. (For the details, refer to the Instruction Manual (Detailed) of the inverter.)
• The restrictions on I/O signals (refer to page 67) remain the same when the other plug-in option (FR-A8AY or FR-A8AR) is
used together with the FR-A8NS.
• Offline auto tuning cannot be performed with the servo system controller. Perform it using the PU or the setup software (FR
Configurator2) before starting communication.
• 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
the MELSEC iQ-R Motion Controller Programming Manual (Common) for details.
• When the MRS signal is ON, create the motion SFC program that turns ON the servo-OFF command of the target axis. To
turn OFF the MRS signal or the servo-OFF command signal, the motor speed must be at 20 r/min or less.
• During the SSCNET III(/H) communication, Pr.998 PM parameter initialization must be set to "0" (initial value).
• Available range of frequency (speed limit value) is 120 Hz.

after the inverter is powered ON in the SSCNET III(/H) operation mode. The warning indication is also
displayed when the communication is established and then shut off. The warning indication disappears when
the communication is established with the servo system controller. Then the inverter becomes ready for
operation.
• The CF warning indication is displayed during initialization (when the SSCNET III(/H) communication status is
"110" to "180"). (Refer to page 28.)
• Check the communication cable for a fault.
• Check that the communication equipment (personal computer) and servo system controller have not been
powered OFF.
• Change the communication cable.
• Power ON the communication equipment (personal computer) and servo system controller.
Not displayed when the SSCNET III(/H) operation is disabled (Pr.499 SSCNET III(/H) operation selection = "9999" (initial value) or the
