(In the panel window, the three digits after “E” indicate an error number.)
Error No. Error name Description, action, etc.
801 SCIF overrun status (IAI protocol reception) Communication failure. Check for noise, connected equipment and communication
setting.
802 SCIF receive ER status (IAI protocol reception) Communication failure. Check for noise, shorted/disconnected communication
cable, connected equipment and communication setting. This error will also occur
when establishing communication with the PC/TP wrongly connected to SIO-CH1
being opened to the user.
803 Receive timeout status (IAI protocol reception) The transfer interval after the first received byte is too long. Possible causes include
disconnected communication cable and error in the connected equipment.
804 SCIF overrun status (SEL reception) Communication failure. Check for noise, connected equipment and communication
setting.
805 SCIF receive ER status (SEL reception) Communication failure. Check for noise, shorted/disconnected communication
cable, connected equipment and communication setting.
806 SCIF receive ER status due to other factor (SEL reception) Communication failure. Take the same action specified for error No. 804 or 805.
807 Drive-source cutoff relay ER status The motor-drive power ON status remains ON even when the drive source is cut off.
The drive-source cut-off relay contacts may have been melted.
808 Power OFF status during slave parameter write The power was turned off while writing slave parameters. (This error can be
detected only when a backup battery is used.)
809 Power OFF status during data write to flash ROM The power was turned off while writing data to the flash ROM. (This error can be
detected only when a backup battery is used.)
80A Expanded-SIO overrun status (SEL reception) Communication failure. Check for noise, connected equipment and communication
setting.
80B Expanded-SIO parity ER status (SEL reception) Communication failure. Check for noise, shorted/disconnected communication
cable, connected equipment and communication setting.
80C Expanded-SIO framing ER status (SEL reception) Communication failure. Check for noise, shorted/disconnected communication
cable, connected equipment and communication setting.
80D Expanded-SIO receive ER status due to other factor (SEL
reception)
Communication failure. Take the same action specified for error No. 80A, 80B or
80C.
80E Expanded-SIO receive buffer overflow status (SEL reception) The receive buffer overflowed. Excessive data was received from outside.
80F Ethernet control status 1 Ethernet control information (for analysis)
810 Ethernet control status 2 Ethernet control information (for analysis)
811 Maintenance information 1 Maintenance information (for analysis)
812 Maintenance information 2 Maintenance information (for analysis)
813 Maintenance information 3 Maintenance information (for analysis)
814 Maintenance information 4 Maintenance information (for analysis)
815 Maintenance information 5 Maintenance information (for analysis)
81A Mounted-SIO overrun status (SEL reception) Communication failure. Check for noise, connected equipment and communication
setting.
81B Mounted-SIO parity ER status (SEL reception) Communication failure. Check for noise, shorted/disconnected communication
cable, connected equipment and communication setting.
81C Mounted-SIO framing ER status (SEL reception) Communication failure. Check for noise, shorted/disconnected communication
cable, connected equipment and communication setting.
81D Mounted-SIO S-receive queue overflow status (SEL reception) The receive queue in the mounted-SIO CPU overflowed. Excessive data was
received from outside.
