6-7
Possible Causes
What to Check and Suggested Measures
(3) The
automatic
deceleration was active.
Check the data of function code H69 (Automatic deceleration
(mode selection)).
Î
Consider the use of a braking resistor.
Î
Increase the deceleration time (F08 and E11).
(4) Overload
Measure the output current.
Î
Lighten the load.
(5) Torque generated by the
motor was insufficient.
Check that the motor starts running if the value of the torque
boost (F09) is increased.
Î
Increase the value of the torque boost (F09).
(6) An external frequency
command device is being
used.
Check that there is no noise in the external signal wires.
Î
Isolate the control signal wires from the main circuit wires as
far as possible.
Î
Use shielded wire or twisted wire for the control signal wires.
[ 7 ] Even if the power recovers after a momentary power failure, the motor does not restart.
Possible Causes
What to Check and Suggested Measures
(1) The setting of function
code F14 is either 0 or 1.
Check if an undervoltage trip occurs.
Î
Change the data of function code F14 (Restart mode after
momentary power failure (mode selection)) to 4 or 5.
(2) The run command stayed
off even after power has
been restored.
Check the input signal with Menu #4 "I/O checking" using the
keypad.
Î
Check the power recovery sequence with an external circuit.
If necessary, consider the use of a relay that can keep the
run command on.
[ 8 ] The inverter does not run as expected
Possible Causes
What to Check and Suggested Measures
Check that all function codes are correctly configured.
Î
Correct the configuration of the function codes.
(1) Wrong
configuration
of function codes
Make a note of function code data currently configured and initialize
all function code data (H03).
Î
After initialization, reconfigure the necessary function codes one
by one, checking the running status of the inverter.
