7-11-2 Communications Option Function

• Use this function when using a CompoNet/DeviceNet Communications Unit to communicate with the
host equipment.
• For details of parameters, refer to the following manuals.
• MX2/RX Series DeviceNet Communications Unit User's Manual (I581)
• MX2/RX Series CompoNet Communications Unit User's Manual (I582)
• Set the network slave address in the DeviceNet MAC ID (P192) or CompoNet Node Address (P190).
• In the Assembly Instance Number (P046), set the remote I/O function of the communications unit.
• If you select the flexible format for the remote I/O function, use the following parameters to configure
the interface for the remote I/O function.
• Option I/F Flexible Format Output Register 1 to 10 (P160 to P169)
• Option I/F Flexible Format Input Register 1 to 10 (P170 to P179)
• To command the inverter frequency reference as a rotation speed, set the number of motor poles in
the Number of Poles for Rotation Speed Setting (P049).
• In the Communications Error Detection Timer Setting (P044), set the function for monitoring the data
communications between the inverter and the communications unit.
• In the Operation Selection at Host Communications Error (P045), set how the inverter should operate
if an error etc. occurs in the host network.
• In the Operation Selection at Idle Mode Detection (P048), set how the inverter should operate when
the network is in the Idle (communications standby) mode.
• You can use a multi-function output terminal built into the inverter as a general-purpose output termi-
nal for the communications host.
To use it as the general-purpose output terminal for the communications host, set the Multi-function
Output P1/P2 Selection (C021/C022) or Multi-function Relay Output (MA, MB) Function Selection
(C026) to 63 (OPO: Option).
