Name
The deviation of the speed reference and
speed feedback exceeded the regulation
level. (F1-10)
Motor has pulled out of synchronization with
the applied stator field.
An uncontrolled motor state results from an
incomplete PG origin pulse adjustment or
from a failed initial magnetic pole estimation.
Both FWD and REV run commands are simul-
taneously input for 500ms or longer.
External base block command is input from
control circuit terminal.
Fault occurred in the external control circuit.
Fault occurred in the external control circuit.
Inverter kVA setting error.
Parameter data is out of range.
Multi-function input settings in H1-01 to H1-06
are not in ascending order. Or, set values
other than "F" are overlapping
• C-option is not connected although run
command from C-option is selected
• C-option is not connected although fre-
quency reference from C-option is selected
PG control card is not connected during flux
vector control.
Description Corrective Action
Check the load.
• Check the motor constants.
• Check the motor tempera-
ture.
• Reduce the ASL gain (C5-
01).
• Reduce the acceleration (C1-
01).
• Check the PG cable connec-
tion.
• Repeat auto-tuning (set T1-
03 = 1, then T1-02 = 2, and
press the digital operator
RUN key).
Check sequence circuit.
Check sequence circuit.
Check the condition of the input
terminal. If the LED lights when
the input is not activated, then
the inverter requires repair.
Check the condition of the input
terminal. If the LED lights when
terminal is not connected, then
the inverter requires repair.
Check and set the parameter
data (O2-04).
Check the parameter data set-
tings.
Check the function selection.
• Check and set the contstant
data.
• Connect the C-option.
Connect PG control card.
