Error No. Error name Description, action, etc.
E63 Message-buffer information type error The message-buffer information type is invalid. E64 Abnormal standby power detection error Abnormal standby power was detected. E65 Regenerative resistance temperature error A regenerative resistance temperature error was detected. E66 AC-power overvoltage error An AC-power overvoltage error was detected. E67 Motor-power overvoltage error A motor-power overvoltage error was detected. E68 Emergency-stop status requiring reset recovery (not error) Reset the emergency stop and then reconnect the power. E69 Abnormal 24-V I/O power source The 24-V I/O power source is abnormal.
E6A Safety-gate open status requiring reset recovery (not error) Close the safety gate and then reconnect the power. E6B Shutdown factor indeterminable error Shutdown factor cannot be determined.
E6C DO output current error The DO output current is abnormal. E6D Drive-source cutoff relay error The drive-source cutoff relay may have been melted.
E71 Encoder configuration information outside supported function
information range
An encoder whose configuration information is outside the range supported by the driver unit is installed.
E72 Motor configuration information outside supported function
information range
A motor whose configuration information is outside the range supported by the driver unit is installed.
E73 Encoder resolution mismatch error The encoder resolution in the system’s axis-specific parameter and that of the
installed encoder do not match.
E74 Encoder division ratio mismatch error The encoder division ratio in the system’s axis-specific parameter and that of the
installed encoder do not match.
E75 Encoder linear/rotary type mismatch error The encoder linear/rotary type in the system’s axis-specific parameter and that of
the installed encoder do not match.
E76 Encoder ABS/INC type mismatch error The encoder ABS/INC type in the system’s axis-specific parameter and that of
the installed encoder do not match.
E77 Magnetic-pole sensor installation specification mismatch error The magnetic-sensor installation specification in the system’s axis-specific
parameter and that of the installed encoder do not match.
E78 Brake installation specification mismatch error The brake installation specification in the system’s axis-specific parameter and
that of the installed encoder do not match.
E79 Abnormal response error when sending EEPROM-data setting slave
command
An abnormal response was received when an EEPROM-data setting slave command was sent.
E7A Maximum receive size over error when sending EEPROM-data
setting slave command
The receive size exceeded the limit value when an EEPROM-data setting slave command was sent.
E7B Motor-drive power ON timeout error Abnormal current flow from the motor-drive power source
E7C Register read/write test error Error reading/writing the register E7D Linear-movement axis parameter error Check axis-specific parameter Nos. 38, 68, 1, etc.
E7E Parameter error The parameter is invalid.
