Thank you for choosing the Mitsubishi transistorized inverter option unit. 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.
2. Injury Prevention CAUTION • Apply only the voltage specified in the instruction manual to each terminal to prevent burst, damage, etc. • Ensure that the cables are connected to the correct terminals. Otherwise, burst, damage, etc. may occur. • Always make sure that polarity is correct to prevent burst, damage, etc. • While power is on or for some time after power-off, do not touch the inverter as it is hot and you may get burnt. 3.

1. INTRODUCTION 1.1 General Thank you for choosing this option unit for the Mitsubishi FR-A500(L)/ F500(L) series transistorized inverters. Please read this manual carefully before using this option unit. This instruction manual gives handling information and precautions for use of this product as well as the information required for the transmission of data to and from the inverter via a Modbus Plus network.
INTRODUCTION 1.
INTRODUCTION Diagnostic LED Status Indicator The green LED located next to the address DIP switch on the Modbus Plus option top board provides indication of communication status. The LED on the bottom board will be solid green if the option CPU acts correctly. The following describes the LED on the top board definitions. Green Flash every 160ms Flash every 1s 2 flashes, off 2s 3 flashes, off 1.7s 4 flashes, off 1.4s State of system Node is working normally.
2. INSTALLATION Remove the drive cover following the inverter instruction manual and install the option unit using the following procedure: 2.1 Pre-Installation Checks (1) Check the inverter type. You may use the option unit only with a FR-A500(L)/F500(L) series inverter. You must not use it with any other series (e.g. A200E, A200, A100, Z and F series).
INSTALLATION (5) Secure the option unit to the inverter with two mounting screws. If the screw holes in the option unit do not line up with the inverter mounting holes, check that the connectors have been fitted correctly. (6) To ensure proper Network Grounding, connect a harness (NOT Supplied) from FR-A5NM Ground terminal to inverter Ground terminal. For ease of routing, the harness should be passed between the Top and Bottom board. (Refer to the following diagram.) Recommended crimping terminal : 1.
INSTALLATION (7) Set the node address before replacing the cover onto the inverter. (Refer to page 7 for node address setting.) (8) Next remove the option data port insert from the inverter cover. Then replace the inverter cover, while making sure that the Modbus Plus connector is aligned with the option data port window. Connect the Modbus Plus cable to the inverter by plugging DB9-style male connector into DB9-style female connector of the option unit, which should be visible in the option port window.
INSTALLATION 2.2 Node address setting (1) Make sure that the inverter power is off and the option unit is mounted in the inverter. Connect the Modbus Plus cable you created to the network. (2) When setting the Modbus Plus address on the option board, use the following table. Refer to page 2 for the address switch location. REMARKS A switch setting of 1 indicates the On position, and a switch setting of 0 indicates the Off position.

INSTALLATION Alternate method for setting the switch: i. ii. iii. iv. To set the node address to be nn, first subtract 1 from it. Convert the result (nn-1) into hexadecimal XXh. Then span it into binary format, padding with 0's in the front 00fedcba. Finally, take the complement 11nmlkji, if a bit is 0, set the switch to Off position; if a bit is 1, set the switch to On position. REMARKS The first two leading position switches are not used.
INSTALLATION 2.3 Communication cable When making a cable for the Modbus Plus protocol, make sure that each end of the cable is terminated with the A5MBKT185 terminator connectors. For nodes between the termination points, use the in-line connectors (A5MBKT085). The cable should be a Modbus Plus standard cable (490NAA271xxF). Connect a wire from the ground terminal on the FR-A5NM to the inverter Chassis to ensure proper grounding of the option board.
INSTALLATION Please connect Modbus connector and the communication cable following the table.
3. OPERATION The operation of the inverter changes slightly when you install this option unit, as described below. 3.1 Operating Modes In the PU operating mode, a Parameter Unit (PU) controls the inverter. In the External-operating mode, the inverter is controlled by external signals connected to the inverter's terminal block. In the Network (computer link) operating mode, the inverter is controlled by commands from a Modbus Plus master. 3.
OPERATION 3.3 Functions Available in the Operating Modes The functions available to the drive depend on the operating mode. The following table indicates the command types available according to the operating mode.
4. ACCESSING DRIVE DATA (1) This option unit acts as a Modbus Plus slave to a PLC or equivalent controller acting as a Modbus Plus master. This means that the option unit: • Acknowledges messages received • Transmits messages at the request of a network master. (2) The option unit can also act as a Modbus Plus slave to a Modbus Plus master that can read the drive's I/O values, as well as configure the drive itself. (3) The option unit cannot send messages on its own, and it has no bus access rights.
5. PARAMETER DEFINITIONS Depending upon which Modbus Plus master device is being used, data registers may be referenced using a 5-digit(4nnnn) or 6-digit(40nnnn) format. For convenience, this manual uses the 5-digit format. When using the 6-digit format, the last 4 digits of the register remain the same and a zero is inserted between the numeral 4 and the 4-digit register number(nnnn). The Modbus Plus option card generates error codes when inappropriate operations occur.
PARAMETER DEFINITIONS Read out data: FFFEh means No parameter. FFFDh means parameter Not Available. Any register that does not appear in any entry of the following tables is considered Reserved.
