Failure
Trip name
code
001D Undercurrent The output current declined to the under-
* current detection level during run.
001E Undervoltage The input voltage (power circuit) declined. • Check the input voltage.
(Power cir-
cuit) *
003C Undertorque * The load torque reached the undertorque
level during run.
0049 Undertorque/ Undertorque or undercurrent on the shock
Undercurrent monitoring function was detected.
*
*Enable/Disable can be selected for trip with a parameter.
English
Panel disconnec- The cable connecting the inverter and panel
tion alarm are disconnected during run with a run
command from the operation panel and
extension panel.
Key failure alarm • [RUN] or [STOP/RESET] key on the operation
panel is pressed and hold for 20 seconds or
more.
• The operation panel key has failed.
Analog input dis- The input level of the terminal [II] became the
connection alarm setting value or less of <F633: II analog input
disconnection detection level> .
Communication
Condition very close to the communication
alarm time out trip.
(embedded Ethernet)
Control power 1) Undervoltage on the control power supply
option alarm input between [+SU] and [CC].
2) The setting of <F647: Control power option
failure detection> is improper.

Measures
• Check the load.
• Check that the undercurrent detection
setting is correct.
<F610: Undercurrent trip>,
<F611: Undercurrent detection level>,
<F612: Undercurrent detection time>, etc.
• Check that the undervoltage detection set-
ting is correct.
<F625: Undervoltage detection level>,
<F627: Undervoltage trip>, etc.
• To avoid trip in momentary power failure,
set <F627> = "0: Disabled", and set
<F301: Auto-restart> and <F302: Regen-
erative power ride-through level> to "1".
• Check the load side.
• Check that the undertorque detection set-
ting is correct.
<F651: Undertorque trip>,
<F652: Undertorque detection level during
power running>,
<F653: Undertorque detection level during
regen>,
<F654: Undertorque detection time>, etc.
• Check the load.
• When no problem is found, check if the
shock monitoring function setting is
correct.
<F590: Shock monitoring> to <F598:
Shock monitoring detection condition>
Measures
Check the connection on the inverter and
panel.
Check the operation panel. If the failure
occurs again, contact your Toshiba
distributor.
• Check that the signal line connected to the
terminal [II] is not disconnected.
• Check that the <F633> setting is correct.
Perform the same measures with
communication time out "E-43".
1) Check the voltage on the control power
supply input between [+SU] and [CC]. 20
Vdc or more is required.
2) When the control power supply option is
not used, set <F647> = "0".
*When [COFF] occurs, turn the power OFF
once, and reset.
