Problems With Inverter Settings - FujiFilm Frenic-Mini Instruction Manual

Possible Causes
(3) The automatic
deceleration was active.
(4) Overload
(5) Torque generated by the
motor was insufficient.
(6) An external frequency
command device is being
used.
[ 7 ] Even if the power recovers after an instantaneous power failure, the motor does not
restart.
Possible Causes
(1) The setting of function
code F14 did not make
the motor restart even if
the power recovered after
an instantaneous power
failure.
(2) The run command stayed
off even after the power
recovered.

6.2.2 Problems with inverter settings

[ 1 ] If the data of function codes cannot be changed
Possible Causes
(1) An attempt was made to
change function code
data that cannot be
changed when the
inverter is running.
(2) The data of the function
codes is protected.
What to Check and Suggested Measures
Check the data of function code H69.
Consider the use of a braking resistor.
Increase the deceleration time (F08 and E11).
Measure the output current.
Lighten the load.
Check that the motor starts running if the value of the torque
boost (F09) is increased.
Increase the value of the torque boost (F09).
Check that there is no noise in the external signal wires.
Isolate the control signal wires from the main circuit wires
as far as possible.
Use shielded wire or twisted wire for the control signal
wires.
What to Check and Suggested Measures
Check if an undervoltage trip occurs.
Change the data of function code F14 to 4 or 5.
Check the input signal with Menu #4 "I/O checking" using the
keypad.
Check the power recovery sequence with an external
circuit. If necessary, consider the use of a relay that can
keep the run command on.
What to Check and Suggested Measures
Check if the inverter is running with Menu #3 "Drive
monitoring" using the keypad and then confirm whether the
data of the function codes can be changed when the motor is
running by referring to the function code tables.
Stop the motor then change the data of the function codes.
Check the data of function code F00.
Disable data protection of function codes.
