5.1.2 Option boards error codes

When an option board is mounted in the optional port 1 (located near the operator connector), the error code
display format is "E6*. " (on the digital operator) or "OP1-*" (on the remote operator). When it is mounted in the
optional port 2 (located near the control circuit terminal block), the error code display format is "E7*. " (on the
digital operator) or "OP2-*" (on the remote operator).

Name
If the encoder wiring is disconnected, an encoder
connection error is detected, the encoder fails, or an
Encoder
encoder that does not support line driver output is
disconnection
used, the inverter will shut off its output and display the
error code shown on the right.
If the motor speed rises to "maximum frequency (A004)
x over-speed error detection level (P026)" or more, the
Excessive speed
inverter will shut off its output and display the error
code shown on the right.
If, in position control mode, the deviation of the current
position from that specified by the positioning
Positioning error command increases to 1,000,000 pulses or more, the
inverter will shut off its output and display the error
code shown on the right.
In absolute position control mode, the inverter shuts off
its output and indicates an error when the range
Position control
specified by the position range specification (forward)
range trip
(P072) or position range specification (reverse) (P073) is
exceeded.
If a faulty connection (i.e., mounting) of the feedback
SJ-FB connection
option board is detected, the inverter will shut off its
error
output and display the error code shown on the right.
Note: If the option board does not operate normally, confirm the DIP switch settings on the option board.
