Be sure to cycle the power supply of the MX2/RX-series Inverter to enable the changes.
Precautions for Correct Use
Precautions for Correct Use
• Be sure that the POWER LED indicator is not lit when cycling the power supply of the
MX2/RX-series Inverter. Note that the time until the light turns off varies with the inverter model.
• Some CompoNet Master Units in market may send Idle messages during specific events
(start-up, PLC program mode, etc). In this case, consider to set Operation at Idle Mode
Detection Setting (P048) to 02 (Ignore).
Special I/O and Flexible Format that utilize the Modbus communication method enable you to control
various inverter functions and parameters through the Remote I/O function.
This section describes how to configure these types of Remote I/O.
Inverter parameters can be configured using the Digital Operator, CX-Drive, or CX-Integrator.
There are two ways of configuring the node address of a CompoNet Communications Unit.
• Use the rotary switches on the front of the Unit to set the node address in the range 0 to 63.
• Setting the rotary switches on the front of the CompoNet Communications Unit to 64 to 99
enables inverter parameters. Configure the node address by setting inverter parameter P190.
Inverter parameter P046 (Assembly Instance No.) sets the type of Remote I/O.
Select the combination of output and input that fits your application requirements.
The settings for Special I/O and Flexible Format are shown below.
• Special I/O:
P046 = 03
• Flexible Format:
P046 = 06
*1 Special I/O differs from the conventional Special I/O in the data format.
*2 If you select Flexible Format, the number of occupied bytes (words) will change depending on the number of
Modbus registers set in parameters P160 to 179.
Additional Information
The CompoNet Communications Unit supports read/write of double-word data.
