(In the panel window, the three digits after “E” indicate an error number.)
Error No. Error name Description, action, etc.
E1F I/O assignment parameter error A value other than an I/O port number (“-1” is acceptable) or other than an I/O
head port number + [multiple of 8] may be input in I/O parameter Nos. 2 to 9, or a value other than a [multiple of 8] may be input in I/O parameter Nos. 14 to 17.
E20 I/O assignment duplication error I/O assignments are duplicated. Check I/O parameter Nos. 2 to 9 and 14 to 17
and the I/O slot card type (number of I/Os), etc.
E21 I/O assignment count over error The I/O assignments exceed the specified range. Check I/O parameter Nos. 2 to
9 and 14 to 17 and the I/O slot card type (number of I/Os).
E22 Header error (Slave communication) The header in the message received from the slave card is invalid. E23 Card ID error (Slave communication) The card ID in the message received from the slave card is invalid. E24 Response type error (Slave communication) The response type in the message received from the slave card is invalid. E25 Command type error (Slave communication) The command type of the transmitting command is invalid. E26 Target type error The target type is invalid. E27 No target error Target (driver card, I/O card, encoder or other slave card) is not installed. E29 EEPROM error (EWEN/EWDS not permitted) EEPROM access error (when writing)
E2A Read compare mismatch error during EEPROM write EEPROM access error (when writing) E2B Abnormal response error when sending EEPROM information
acquisition command
An abnormal response was received when a slave-EEPROM information acquisition command was sent.
E2C Maximum receive size over error when sending EEPROM
information acquisition command
The maximum receive size exceeds the limit value when a slave-EEPROM information acquisition command is sent.
E2D Receive-data checksum error when sending EEPROM information
acquisition command
The checksum of receive data is invalid when a slave-EEPROM information acquisition command is sent.
E33 Slave response logic error The slave response logic is invalid. E34 Slave block number out of range The slave block number is out of range. E37 Slave data setting prohibited Setting of slave data is prohibited. E38 Faulty slave EEPROM The slave EEPROM is faulty. E39 No encoder EEPROM error The encoder is not equipped with EEPROM.
E3A Absolute encoder error Absolute encoder is specified illegally.
E3C Undefined slave-command error code detected An undefined slave-command error code was detected. E3D SEL program/point/parameter flash ROM status error Data is not written to the flash ROM correctly or written in an old, incompatible
application version.
E3E Parameter checksum error The flash ROM data has been destroyed.
E3F Gain parameter error The setting of “Axis-specific parameter No. 60, Position gain,” etc., is invalid.
E40 Rotational-movement axis parameter error Check axis-specific parameter Nos. 67, 66, 38, 37, 1, etc. E41 Servo-motion data packet shortage error There are not enough servo-motion data packets.
