Warning
Fault contacts
do not change
state.
BB (External baseblock)
Baseblock command at multi-
function terminal is active.
The inverter output is shut
OFF (motor coasting).
Temporary condition is
cleared when input command
is removed. Check the external
circuit (sequence).

EF (Simultaneous FWD/REV
run commands)
When FWD and REV run
commands are
simultaneously input for over
500ms, the inverter stops
according to parameter n005. Check the external
circuit (sequence).
Blinking
STP (Operator function stop)
STOP
RESET is pressed during
running by the control circuit
terminals FWD/REV
command, or by the run
command from
communications. The inverter
stops according to parameter
n005.
STP (Emergency stop)
Inverter receives emergency
stop alarm signal. Inverter
stops according to parameter
n005. Open FWD/REV
command of control
circuit terminals.
Check the external
circuit (sequence).
Blinking
FAN (Cooling fan fault)
Cooling fan is locked. Check the following:
• Cooling fan
• Cooling fan wiring is
not connected.
Blinking
CE (MEMOBUS)
communications fault Check the
communication devices
or communication
signals.
FBL (PID feedback loss
detection)
PID feedback value drops
below the detection level.
When PID feedback loss is
detected, the inverter
operates according to the
n136 setting. Check the mechanical
system and correct the
cause, or increase the
value of n137.
Blinking
Option card communications
fault.
Communication fault has
occurred in a mode that run
command and frequency
reference are set from the
communication option card. Check the
communication devices
or communication
signals.
