CompoNet Communications Unit User’s Manual (I582-E1)
The following modes are disabled when the CompoNet Communications Unit is used with an inverter.
• PM Motor mode
• High Frequency mode
When the CompoNet Communications Unit is used, the MX2/RX-series RS485 communications (Mod-
bus) port is disabled.
In addition, when the MX2-series is used with an inverter, the external Digital Operator is disabled with
RJ45 connector function.
The MX2/RX-series Inverter can be set to the Heavy Load or Light Load mode.
Switching from the default Heavy Load mode to the Light Load mode disables the vector control and
torque control.
As a result, in the Light Load mode, the following restrictions arise.
• The Light Load mode disallows writing of the torque reference, configuring a Remote I/O allocation
that includes torque reference data results in an error.
• In CX-Integrator, editing of device parameters using the EDS file is disabled. Because the Light Load
mode disallows writing of some parameter data, you cannot use the EDS file to download parame-
ters. If you execute a download, an error will occur when a write-prohibit parameter is encountered,
causing the process to be terminated.
Precautions for Correct Use
Precautions for Correct Use
To edit parameters via network, use the Inverter/Servo support software CX-Drive to establish
connection via an OMRON PLC and CompoNet.
If you use CX-Integrator to edit device parameters with an EDS file, you cannot edit the second and
third control parameters of the inverter.
