7-11 Option/Applied Functions (Group P)
This section describes the functions associated with option unit connected to the option unit connector,
as well as the applied functions of the inverter.
Select whether to have the inverter trip or continue operation with the error from the option unit ignored,
if an error caused by the option unit connected to the connector for option unit.
• 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
