Option Boards Error Codes - Hitachi SJ700B Series Instruction Manual

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).

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
Excessive speed
more, the 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 error positioning 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

range trip
(forward) (P072) or position range specification
(reverse) (P073) is exceeded.
If a faulty connection (i.e., mounting) of the
SJ-FB connection feedback option board is detected, the inverter will
error shut off its 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.
