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
What to Check and Suggested Measures
(1) No power supplied to the
drive.
CHECK
Check nput voltage, output voltage and interphase imbalance.
SUGGESTED ACTIONS
– Connect a molded case circuit breaker, a ground fault circuit interruptor (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.
(2) No forward/reverse
operation command
was input, or both the
commands were inputted
simultaneously (external
signal operation).
CHECK
Check input status of the forward/reverse command using Menu #4 “I/O checking.”
SUGGESTED ACTIONS
– 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.
– If the printed circuit board is malfunctioning, replace it.
(3) No indication of rotation
direction (keypad opera-
tion).
CHECK
Check input status of the forward/reverse rotation direction command using Menu #4 “I/O checking.”
SUGGESTED ACTIONS
– Input the rotation direction (F02=0), or select the keypad operation with which the rotation direction is
fixed (F02=2 or 3).
(4) The drive could not ac-
cept any run commands
from the keypad because
it was not in Run mode.
CHECK
Check which operation mode the drive is in.
SUGGESTED ACTIONS
– Make a transition from existing mode to Run mode.
(5) A run command with
higher priority than the
one attempted was
active, and the run
command was stopped.
CHECK
Check the higher priority run command with using Menu #2 “Data checking” and Menu #4 “I/O checking,”
while referring to the block diagram of the drive command generator*.
*Refer to Chapter 4 in the AF-300 Mini User’s Manual.
SUGGESTED ACTIONS
– Change any incorrect function code data settings (e.g., cancel the higher priority run command).
(6) The set frequency was
set to the same or
lower than the value
of the starting or stop
frequency.
CHECK
Check that a frequency command has been input, using Menu #4 “I/O checking.”
SUGGESTED ACTIONS
– 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 to lower values.
– Inspect the frequency command devices, signal converters, switches or relay contacts. Replace any that
are faulty.
– Connect the external circuit wires correctly to terminals [13], [12], [11] and [C1].
(7) A run command with
higher priority than
the one attempted
was active and the set
frequency was set to the
same or lower than the
value of the starting or
stop frequency.
CHECK
Check the higher priority run command using Menu #2 “Data checking” and Menu #4 “I/O checking,”
while referring to the block diagram of the drive command generator.
*Refer to Chapter 4 in the AF-300 Mini User’s Manual.
SUGGESTED ACTIONS
– Correct any incorrect function code data settings (e.g. cancel the higher priority run command).
(8) The peak and minimum
frequencies for the
frequency limiters were
set incorrectly.
CHECK
Check the data for function codes F15 and F16.
SUGGESTED ACTIONS
– Change the peak and minimum frequencies (F15 and F16) to the correct ones.
