Thank you for choosing this Mitsubishi inverter plug-in option.

Warning

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 optio n 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.

 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 be fore packaging the product.

Trial run

 Before starting operation, each parameter must 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 fault 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.

example

Set the node address between "1 to 64" using node address switches on the FR-A8NF (refer to page 8). The setting is applied at the next power-on.

Set the arrow ( ) of the corresponding switches to the number to set a desired node address.

• Setting example

Node address 1: Set the arrow () of X10 (SW2) to "0" and the arrow () of X1 (SW1) to "1".

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 switches so that the arrow points the exact position. If the switch is set between numbers, normal data communication can not be established.

• If the node address switch is set to a value other than "1 to 64", it is invalid due to outside of setting range. In this case, DEV LED of the option is lit red and E.OPT appears on the operation panel of the inverter.

• You cannot set the same node address to other devices on the network. (Doing so disables proper communication.)

• Changes in the node address setting are applied only at the next power-ON. Therefore, if the node address setting is changed, make sure to power OFF and ON the inverter power.

INSTALLATION

Node address 26: Set the arrow () of X10 (SW2) to "2" and the arrow () of X1 (SW1) to "6".

INVERTER SETTING

 Operation mode switching by the PU operation interlock signal (X12)

PU operation interlock is a function that forcefully changes the operation mode to the Network operation mode at turn-OFF of the X12 signal (Bit 11), which gives operation commands through the FL remote communication. This function prevents the operation mode from being accidentally unswitched from the PU operation mode. If the operation mode left unswithced from the PU operation mode, the inverter does not reply to the commands sent through the FL remote communication.

Cyclic transmission transmits data periodically. Each node shares data through common memory. (Refer to page 41 for common memory. ) Data of I/O area is updated periodically by cyclic transmission.

The master controls the inverter by setting run command (control input command, set frequency, etc.) in the output data area. The inverter sets the inverter status (output frequency, output current, various signals, etc.) in the input data area and sends it to the master.

CYCLIC TRANSMISSION

6.1 Common memory

Concept of common memory is stated below.

• The common memory is used as a shared memory between nodes which perform cyclic transmission.

• The common memory has two areas which are "common memory area 1" and "common memory area 2". Common memory area 1 is I/O data area. Common memory area 2 is the control information area. Two different areas can be assigned to each node.

• When the area each node sends exceed the transmission size (1024 byte) by one frame, data is transmitted by multiple frames.

• When receiving data which are divided into multiple frames, common memory is not updated until all frames sent from one node are received. Synchronism per node unit is guaranteed.

• Entire network has an area of 8k bit (0.5k word) + 8k word = 8.5k word. The maximum send data capacity per one node is 8.5k word. (Note that one word is 2 byte.)

CYCLIC TRANSMISSION

area

• Among common memory, both common memory area 1 and common memory 2 can be set as a transmission area of one node as desired within the maximum area.

• Each node on the FL remote network can share the same data in the whole system by broadcasting data at a constant period. In addition, each node has own transmission area which does not overlap each other to exchange data. (For common memory function, the transmission area assigned to one node is a receive area for each of the other nodes.)

The control circuit capacitor life is calculated from the energization time and temperature according to the operating status, and is counted down from 100%. A warning is output when the control circuit capacitor life falls below 10%. (The setting value goes back to 0 when the part is replaced.)

0: without warning, 1: with warning On the assumption that the main circuit capacitor capacitance at factory shipment is 100%, the capacitor life is checked every time measurement is made. A warning is output when the measured value falls below 85%. The life check of the main circuit capacitor can be performed by measuring at the maintenance time, etc. After setting "1" in Pr.259 Main circuit capacitor life measuring, switch OFF power once, then ON again to check that Pr. 259 = "3" (measuring completion). (The setting value goes back to 0 when the part is replaced.)

0: without warning, 1: with warning This function detects that the cooling fan speed falls 50% or below and outputs a warning. (The setting value goes back to 0 when the part is replaced.)

Message transmission is a non-periodic data communication method to communicate to a specified node when send request is given. Basic function of message transmission is as follows.

• When a node receives a token, one frame can be sent before sending cyclic frame.

• The message frame size which can be sent at a time is 1024 byte maximum.

Message frame

1024 byte

• This method applies algorithm which controls refresh time not exceeding refresh cycle permissible time.

• Two transmission functions are available. One is "one-to-one message transmission" to send to specified nodes, and another is "one-to-n message transmission" to send to all nodes.

• For "one-to-one message transmission", whether the target node has received data correctly or not is checked. For "one-to-n message transmission", response is not given after receipt of a message.
