Remedies
• Close the ST-CC circuit.
• Measure the main circuit supply voltage.
If the voltage is at a normal level, the
inverter requires repairing.
• The inverter is normal if it restarts after
several tens of senconds.
The inverter restarts automatically. Be
careful of the machine because it may
suddenly restart.
• Set the frequency setting signals at points
1 and 2 apart from each other.
• Press the STOP key again to clear the
trip.
• Press the STOP key for an emergency
stop.
To cancel the emergency stop, press any
other key.
• Check whether the setting is made cor-
rectly.
• Press MODE key to exit the data group.
• The message goes off in several tens of
seconds if no problem occurs. Note)
• Normal if the message disappears when
a stop command is entered (or the opera-
tion command is canceled).
• Lower the fequency free unit magnifica-
tion .
• To restart operation, reset the inverter or
input an operation signal again.
• To deactivate the automatic stop function,
increase the frequency command above
the lower-limit frequency (LL) + 0.2 Hz or
turn off the operation command.
• Normal if the message disappears after a
while (several seconds to several tens of
seconds).
• Check the operation panel.
• Normal if it the message disappears after
a few seconds.
