INTRODUCTION 3 Diagnostic LED Status Indicator The green LED located next to the address DIP switch on the ModbusPlus option top board provides indication of communication status. TheLED on the bottom board will be solid green if the option CPU actscorrectly. The following describes the LED on the t...

4 2. INSTALLATION Remove the drive cover following the inverter instruction manual andinstall 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 a...

INSTALLATION 5 (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) fr...

INSTALLATION 7 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 th...

INSTALLATION 9 Alternate method for setting the switch: i. To set the node address to be nn, first subtract 1 from it. ii. Convert the result (nn-1) into hexadecimal XXh. iii. Then span it into binary format, padding with 0's in the front 00fedcba. iv. Finally, take the complement 11nmlkji, if a bit...

INSTALLATION 10 2.3 Communication cable When making a cable for the Modbus Plus protocol, make sure that eachend 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 stan...

12 3. OPERATION The operation of the inverter changes slightly when you install this optionunit, as described below. 3.1 Operating Modes In the PU operating mode, a Parameter Unit (PU) controls the inverter. Inthe External-operating mode, the inverter is controlled by external signalsconnected to th...

OPERATION 13 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 tothe operating mode. *1 Depends on the value of Pr. 338 and Pr. 339.*2 Depends on the value set in Pr. 7...

14 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...

15 5. PARAMETER DEFINITIONS Depending upon which Modbus Plus master device is being used, dataregisters may be referenced using a 5-digit(4nnnn) or 6-digit(40nnnn)format. For convenience, this manual uses the 5-digit format. When usingthe 6-digit format, the last 4 digits of the register remain the ...
