This alarm occurs in case of
trouble with braking circuit.
This alarm occurs if error oc-
curs in arithmetic operation
(division) by CPU, due to impro-
perly set parameter.
This alarm occurs if motor speed
exceeds 115% of the maximum mo-
tor speed.
This alarm occurs if current
larger than the specified maxi-
mum current flows into FR-SFJ.
If voltage on main circuit capa-
citor exceeds the specified max-
imum level, due to regenerative
energy, during acceleration of
motor.
check error occurs in data
transmission between M300 series
CNC and FR-SFJ (when FR-SFJ is
connected to CNC through bus
line).
This'alarm occurs if data trans-
fer does not go satisfactorily
(when FR-SFJ is connected to CNC
