6−10
Error
Code
Name Cause(s)
E40
Operator connection When the connection between inverter and
operator keypad failed, inverter trips and displays
the error code.
E41
Modbus communication error When “trip” is selected (C076=00) as a behavior in
case of communication error, inverter trips when
timeout happens.
E43
EzSQ invalid instruction The program stored in inverter memory has been
destroyed, or the PRG terminal was turned on
without a program downloaded to the inverter.
E44
EzSQ nesting count error Subroutines, if-statement, or for-next loop are
nested in more than eight layers
E45
EzSQ instruction error Inverter found the command which cannot be
executed.
E50
to
E59
EzSQ user trip (0 to 9) When user –defined trip happens, inverter trips
and displays the error code.
E60
Option error (DeviceNet
Communications error)
If the disconnection due to the Bus-Off signal or
timeout occurs during the operation using
DeviceNet commands, the inverter will shut off its
output and display the error code shown on the
right.
(The inverter will trip according to the settings of
"p45" and "P048".)
E61
Option error (duplicated MACID) If two or more devices having the same
MAC ID are detected in the same network, the
inverter will display the error code shown on the
right.
E62
Option error (External trip) If the Force Fault/Trip bit of Attribute 17 in the
Instance 1 of the Control Supervisory object is set
to "1", the inverter will shut off its output and
display the error code shown on the right.
E63 to
E68
Option error The inverter detects errors in the option board
mounted in the optional slot. For details, refer to
the instruction manual for the mounted option
board.
E69
Option error (inverter
communication error)
If timeout occurs during the communication
between the inverter and DeviceNet option board,
the inverter will shut off its output and display the
error code shown on the right.
E80
Encoder
disconnection
If the encoder wiring is disconnected, an encoder
connection error is detected, the encoder fails, or an
encoder that does not support line driver output is
used, the inverter will shut off its output and display
the error code shown on the right.
E81
Excessive speed If the motor speed rises to "maximum frequency
(A004) x over-speed error detection level (P026)" or
more, the inverter will shut off its output and
display the error code shown on the right.
E83
Positioning range error If current position exceeds the position range
(P072-P073), the inverter will shut off its output
and display the error code.
