Monitor
(blink)
Electron thermal operation
When the output current reaches the electron thermal level and the
timer starts, the indication on the monitor will blink.
When the direct voltage becomes approx. DC 200 V or less for AC 200
V , or the direct voltage becomes approx. DC 100 V or less for AC 100 V,
the inverter output will be interrupted since it is taken as
"instantaneous interruption".
For AC 200 V, the control circuit will be reset when the DC becomes 75
V or less.
If the voltage is restored before the control circuit is reset, the system
can resume the operation automatically.
If the operation command was given when the system was restored
from instantaneous interruption during operation, automatic
resumption is prevented and it will be tripped.
If the control circuit is reset, this function does not work.
0.C.
When the output current of the converter exceeds the current which is
set to each inverter, it will be tripped.
0.C.-U
When the output current of the converter exceeds the current which is
set to each inverter during acceleration, it will be tripped.
0.C.-d
When the output current of the converter exceeds the current which is
set to each inverter during slowdown, it will be tripped.
0.C.-C
If the detected value exceeds the current set to each inverter,
it will be tripped.
0.U.
Regeneration overvoltage
protection
When the direct voltage of the converter becomes DC 400 V or more for
AC 200 V , or becomes DC 200 V or more for AC 100 V, it will be tripped.

Overload protection function
(electron thermal)
If the motor current continues to flow with 100% or more, it will be
taken as overload and it will be tripped. While the current
continues to flow, the 5-digit LED will blink.
0.H. Radiating fin overheating protection
When the radiating fin heats up, the temperature sensor will be turned
on and it will be tripped.
E..-0.S. Overspeed protection
When the rotation number exceeds 1.5 times the upper limit speed,
it will be tripped.
E..-C.S. Sensor failure protection When CS signal failure is detected, it will be tripped.

CPU error When the control microcomputer failure is detected, it will be tripped.
CAU. Self-check warning
When the parameter such as "16 operation order selection" is
changed, it will be tripped.
0.L. External forced protection
When the point between "applicable terminal" and "SG" is opened with
"47I5 function selection" or "48I6 function selection" set to external
forced trip, it will be tripped.
When "d2 rotation failure detection" is set to "yes" and rotation failure of
the set speed is detected, it will be tripped.
