Warning
Caution
Caution
This Instruction Manual provides handling information and precautions for use of this product. Incorrect handling might cause an unexpected
fault. Before using this product, always read this Instruction Manual carefully to use this product correctly.
Please forward this Instruction Manual to the end user.
Safety instructions
Do not attempt to install, operate, maintain or inspect the 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".
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.
Electric shock prevention
Incorrect handling may cause 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.
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.
1
Additional instructions
The following instructions must be also followed. If the product is handled incorrectly, it may cause unexpected fault, an injury, or an electric
shock.
Caution
Transportation and mounting
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 substance such as oil.
If halogen-based materials (fluorine, chlorine, bromine, iodine, etc.) infiltrate into a Mitsubishi product, the product will be damaged. Halogen-based materials are
often included in fumigant, which is used to sterilize or disinfest wooden packages. When packaging, prevent residual fumigant components from being infiltrated
into Mitsubishi products, or use an alternative sterilization or disinfection method (heat disinfection, etc.) for packaging. Sterilization of disinfection of wooden
package should also be performed before packaging the product.
Trial run
Before starting operation, each parameter mu st be confirmed and adjusted. A failure to do so may cause some machines to make unexpected motions.
Warning
Usage
Do not modify the equipment.
Do not perform parts removal which is not instructed in this manual. Doing so may lead to fa ult or damage of the product.
Caution
Usage
When parameter clear or all parameter clear is performed, the required parameters must be set again before starting operations. Because all parameters return to
their initial values.
To avoid damage due to static electricity, static electricity in your body must be discharged before you touch the product.
Maintenance, inspection and parts replacement
Do not carry out a megger (insulation resistance) test.
Disposal
The product must be treated as industrial waste.
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 Instruction Manual must be followed when operating the inver ter.

Set the node address between "H00" and "H7D" using the node address switches on the FR-A8NP board. (Refer to page 8.)
The setting is applied at the next power-ON.
Set the arrow () of the corresponding switches to a number or an alphabet to set a desired address.
• Setting example
Node address 1:
Set the "
(SW2) to "1".
" of X16 (SW3) to "0" and the " " of X1
NOTE
• Set the inverter node address before switching ON the inverter and do not change the setting while power is ON.
Otherwise you may get an electric shock.
• Set the node address switch to the switch number (alphabet) position correctly. If the switch is set between numbers,
normal data communication cannot be established.
• When the node address switches are set to any of H7E to HFF, the node address is recognized as H7D.
• The node addresses, H00, H01, H02, H7C, and H7D, may not be available for some master modules.
• You cannot set the same node address to other devices on the network. (Doing so disables proper communication.)

Operation mode can not be directly changed between the PU operation mode and Network operation mode.
The Pr.340 settings "2 or 12" are mainly used for communication operation using the inverter RS-485 terminal.
When a value other than "9999" (selection of automatic restart after instantaneous power failure) is set in Pr.57 Restart coasting time,
the inverter will resume the same operation state which was in before after power has been restored from an instantaneous power failure.
When Pr.340 = "1 or 10", a start command turns off if power failure has occurred and then restored during a start command is on.
Switching between the PU and NET operation modes is available with the key on the operation panel or the X65 signal.
Refer to page 67 for a switching method from the network.

4.3.1 Operation selection at communication error occurrence (Pr.500 to Pr.502, Pr.779)
You can select operations at communication error occurrences by setting Pr.500 to Pr.502, Pr.779 under network operation.
Waiting time for the communication line error output after a communication error
Waiting time for the communication error output after a communication line error occurrence can be set.
Pr. Name Setting range
500 Communication error execution waiting time 0 to 999.8 s 0.1 s 0 s
When a communication line error occurs and lasts longer than the time set in Pr.500, it is recognized as a communication error.
If the communication returns to normal within the time, it is not recognized as a communication error, and the operation
continues.

At the point of communication line error occurrence, Pr.501 Communication error occurrence count display is incremented
by 1.
The cumulative count of communication error occurrences is counted from 0 to 65535. When the count exceeds 65535, the
displayed value is cleared and the counting starts over from 0 again.
NOTE
• Communication error count is temporarily stored in the RAM memory. The error count is stored in EEPROM only once
per hour. If power reset or converter reset is performed, Pr.501 setting will be the one that is last stored to EEPROM
depending on the reset timing.
Inverter operation at a communication error occurrence
How the inverter operates at a communication line error or an option unit fault can be set.
Pr. Name Setting range Description

When a communication error occurs, the inverter
operates at the set frequency.
The inverter operates at the frequency set before
the communication error occurs.
