2.2 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).

2.2.1Error indications by protective functions with the feedback option board (SJ-FB) mounted

Name	Description
	If the encoder wiring is disconnected, an encoder
Encoder	connection error is detected, the encoder fails, or an
	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
Excessive speed	(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.
	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
Position control	off its output and indicates an error when the range
	specified by the position range specification
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.
