If No Alarm Code Appears On The Led Monitor; Motor Is Running Abnormally - FujiFilm Frenic-Mini Instruction Manual

6.2 If no alarm code appears on the LED monitor

6.2.1 Motor is running abnormally

[ 1 ] The motor does not rotate.
Possible Causes
(1) No power supplied to the
inverter.
(2) No forward/reverse
operation command was
inputted, or both the
commands were inputted
simultaneously (external
signal operation).
(3) No indication of rotation
direction (keypad
operation).
(4) The inverter could not
accept any run
commands from the
keypad since it was not in
Running mode.
(5) A run command with
higher priority than the
one attempted was active,
and the run command
was stopped.
(6) The set frequency was
set to the same or lower
than the value of the
starting or stop frequency.
What to Check and Suggested Measures
Check the input voltage, output voltage and interphase
voltage unbalance.
Turn on a molded case circuit breaker, an earth leakage
circuit breaker (with the exception of those exclusively
designed for protection from ground faults) or a magnetic
contactor.
Check for voltage drop, phase loss, poor connections, or
poor contacts, and fix them if necessary.
Check the input status of the forward/reverse command with
Menu #4 "I/O checking" using the keypad.
Input a run command.
Set either the forward or reverse operation command to off
if both commands are being inputted.
Correct the assignment of commands (FWD) and (REV) to
function codes E98 and E99.
Connect the external circuit wires to control circuit
terminals [FWD] and [REV] correctly.
Check the input status of the forward/reverse rotation
direction command with Menu #4 "I/O checking" using the
keypad.
Input the rotation direction (F02=0), or select the keypad
operation with which the rotation direction is fixed (F02=2
or 3).
Check which operation mode the inverter is in, using the
keypad.
Shift the operation mode to Running mode.
While referring to the block diagram of the drive command
generator *, check the higher priority run command with Menu
#2 "Data checking" and Menu #4 "I/O checking" using the
keypad.
* Refer to the FRENIC-Mini User's Manual (MEH446), Chapter 4.
Correct any incorrect function code data settings (e.g.,
cancel the higher priority run command).
Check that a frequency command has been entered, with
Menu #4 "I/O checking" using the keypad.
Set the value of the set frequency to the same or higher
than that of the starting or stop frequency (F23 or F25).
Reconsider the starting and stop frequencies (F23 and
F25), and if necessary, change them to lower values.
Inspect the frequency
converters, switches or relay contacts. Replace any ones
that are faulty.
Connect the external circuit wires correctly to terminals
[13], [12], [11] and [C1].
