Detailed information of error/warning event
The items displayed in the detailed information, which vary depending on each error category, are configured by the items
shown in the table below.
Error category Detailed information 1

H/W error
Positioning control in Axis information
common • Axis in which an event occurred
Home position return • Axis operation status
Absolute position restoration • Start No.
Manual control • Data No. in which an event occurred
Positioning operation • Factor axis
Block start data • Block start Point No. at start
Positioning data • Block start Point No. at occurrence
Speed-torque control • Data by each error
*3
Cam data operation
Synchronous control (Input Axis information
axis) • Axis in which an event occurred (For a
synchronous encoder axis, 800 + Axis No.)
• Axis operation status (For a synchronous
encoder axis, always 0)
• Data by each error
Synchronous control (Output Axis information
axis) • Axis in which an event occurred
• Axis operation status
• Cam data No. when an error occurred
• Data by each error
Servo amplifier Axis information
• Axis in which an event occurred
• Axis operation status
• Start No.
• Data No. in which an event occurred
• Block start Point No. at start
• Block start Point No. at occurrence
• Connected device
• Servo alarm
• Data by each error
I/F System information
• Hold error • Number of write accesses to flash ROM
• Flash ROM error • Data by each error
• CPU module error
Parameter setting range Axis information
error • Axis in which an event occurred
• Common parameter • Data by each error
• Basic parameter
• Detailed parameter
• Home position return
parameter
• Expansion parameter
• Servo parameter
*1 Output only at positioning control. Otherwise, "-" is output.
At the time other than the positioning control (during home position return or JOG operation, etc.), judge the timing of when an error
occurred by the axis operation status.
*2 For common parameters, an axis in which an event occurred is set to "Axis 1".
*3 For an error code which is independent of an axis, the information for an axis in which an event occurred is not displayed.
(For an error code which is independent of an axis, refer to the following.
Page 574 TROUBLESHOOTING)
*4 The following table shows the display of the start No., data No. in which an event occurred, block start point No. at start, and block start
point No. at occurrence.
