1 Overview of Errors
Errors Related to EtherCAT Communications, EtherCAT Slaves, and
NX Units
The following Motion Control Function Module error can occur due to errors in EtherCAT communica-
tions, EtherCAT slaves, or NX Units.

Slave Error

*1 When an error occurs in communications with an EtherCAT slave, an error also occurs in the EtherCAT Master
Function Module. If you assign more than one device to the same axis, a communications error occurs for the
axis if a communications error occurs for even one of the devices.
*2 When an error occurs in slave communications, home becomes undefined for the axis.
Servo Drive Errors
This section describes the notification that is provided for errors that occur in OMRON 1S-series Servo
Drives and G5-series Servo Drives.
There is a difference between the timing of when the Motion Control Function Module detects the error
in the Servo Drive and when the error code is obtained from the Servo Drive. The Motion Control Func-
tion Module therefore reports different events for the error in the Servo Drive and the error code.
 Error Notification
When the Motion Control Function Module detects an error, a Slave Error Detected minor fault level
error (742F0000 hex) occurs. At this point, the Motion Control Function Module performs the error
operation (i.e., it turns OFF the Servo).
 Error Code Notification
When the Servo Drive reports the error code, the Motion Control Function Module generates a
Slave Error Code Report information event (94220000 hex). The error code (the main part of the
error display number) from the Servo Drive is included in the lower two digits of the attached infor-
mation of the Slave Error Code Report event. For example, if the attached information is displayed
as FF13, the error with display number 13 (Main Circuit Power Supply Undervoltage) occurred in the
Servo Drive.
Precautions for Correct Use Precautions for Correct Use
You must change the settings to receive notification of the Slave Error Code Report event. Map

Cause
The Servo is turned OFF for the
axis with an error and operations
other than error resets are not
acknowledged.
