Thank you for choosing this Mitsubishi Inverter plug-in option.
This Instruction Manual gives handling information and
precautions for use of this equipment. Incorrect handling might
cause an unexpected fault. Before using the equipment, please
read this manual carefully to use the equipment to its optimum.
Please forward this manual to the end user.
This section is specifically about
safety matters
Do not attempt to install, operate, maintain or inspect this
product until you have read through this Instruction Manual and
appended documents carefully and can use the equipment
correctly. Do not use this product until you have a full
knowledge of the equipment, safety information and
instructions.
In this Instruction Manual, the safety instruction levels are
classified into "WARNING" and "CAUTION".
Incorrect handling may cause
WARNING
CAUTION
The level may even lead to a serious
consequence according to conditions. Both instruction levels
must be followed because these are important to personal
safety.
CAUTION
hazardous conditions, resulting in
death or severe injury.
Incorrect handling may cause
hazardous conditions, resulting in
medium or slight injury, or may cause
only material damage.
SAFETY INSTRUCTIONS
1. 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.
• Even if power is OFF, do not remove the front cover except for
wiring or periodic inspection. You may accidentally touch the
charged inverter circuits and get an electric shock.
• Before wiring or inspection, power must be switched OFF. To
confirm that, LED indication of the operation panel must be
checked. (It must be 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
are no residual voltage using a tester or the like. The
capacitor is charged with high voltage for some time after
power OFF, 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.

2. Injury Prevention
3) Usage
CAUTION
• The voltage applied to each terminal must be the ones
specified in the Instruction Manual. Otherwise burst, damage,
etc. may occur.
• The cables must be connected to the correct terminals.
Otherwise burst, damage, etc. may occur.
• Polarity must be correct. Otherwise burst, damage, etc. may
occur.
• While power is ON or for some time after power-OFF, do not
touch the inverter as they will be extremely hot. Doing so can
cause burns.
3. Additional Instructions
Also the following points must be noted to prevent an accidental
failure, injury, electric shock, etc.
1) Transportation and mounting
CAUTION
• Do not install or operate the plug-in option if it is damaged or
has parts missing.
• Do not stand or rest heavy objects on the product.
• The mounting orientation must be correct.
• Foreign conductive objects must be prevented from entering
the inverter. That includes screws and metal fragments or
other flammable substances such as oil.
2) Trial run
CAUTION
• Before starting operation, each parameter must be confirmed
and adjusted. A failure to do so may cause some machines to
make unexpected motions.
WARNING
• Do not modify the equipment.
• Do not perform parts removal which is not instructed in this
manual. Doing so may lead to fault or damage of the inverter.
CAUTION
•
When parameter clear or all parameter clear is performed, the
required parameters must be set again before starting operations
because all parameters return to the initial value.
• For prevention of damage due to static electricity, nearby
metal must be touched before touching this product to
eliminate static electricity from your body.
4) Maintenance, inspection and parts replacement
CAUTION
• Do not test the equipment with a megger (measure insulation
resistance).
5) Disposal
CAUTION
• This inverter plug-in option must be treated as industrial
waste.
6) General instruction
Many of the diagrams and drawings in this Instruction Manual
show the inverter without a cover or partially open for
explanation. Never operate the inverter in this manner. The
cover must be reinstalled and the instructions in the inverter
manual must be followed when operating the inverter.

2) Mount the hex-head screw for option
mounting into the inverter screw hole
(on earth plate) (size 5.5mm, tightening
torque 0.56Nxm to 0.75Nxm).
3) Securely fit the connector of the plug-in
option to the inverter connector along
the guides.
4) Securely fix the both right and left sides
of the plug-in option to the inverter with
the accessory mounting screws.
(Tightening torque 0.33Nxm to
0.40Nxm)
If the screw holes do not line up, the
connector may not have been plugged
securely. Check for loose plugging.

INSTALLATION
CAUTION
• Only one type of option per inverter may be used. When two or more options are mounted, priority is in the
order of inverter option connectors 1, 2 and 3. The options having lower priority are inoperative.
• When the inverter cannot recognize that the option is mounted due to improper
installation, etc., " to " (option fault) are displayed. The errors
shown differ according to the mounting positions (connectors 1, 2, 3).
• When mounting/removing an option, hold the sides of the option. Do not press
on the parts on the option circuit board. Stress applied to the parts by pressing, etc. may cause a failure.
• Take caution not to drop a hex-head screw for option mounting or mounting screw during mounting and
removal.
• Pull the option straight out when removing. Pressure applied to the connector and to the option circuit
board may break the option.

2.4 Wiring
(1) Use twisted pair shield cables (0.2mm2 or larger) to connect the FR-
A7AP and position detector.
To protect the cables from noise, run them away from any
source of noise (e.g. the main circuit and power voltage).
Wiring Length
Within 10m At least 2 cables
Within 20m At least 4 cables
Within 100m * At least 6 cables
* When differential driver is set and a wiring length is 30m or more
The wiring length can be extended to 100m by slightly increasing the power by
5V (approx. 5.5V) using six or more cables with gauge size of 0.2mm
parallel or a cable with gauge size of 1.25mm
applied should be within power supply specifications of encoder.
