[Pre-alarm information]
Each message in the table is displayed to give a warning but does not cause the inverter to trip.
The following error code and the frequency will flash alternately.

If two or more problems arise simultaneously, one of the following pre-alarms appears and blinks.
, , (The blinking alarms , , , h, t are displayed in this order from left to right.)
Problem Possible causes
 The detailed information of past trip is
read by pushing the center of setting dial
during blinking nerr ⇔ number.
 No new record of past trip, after past trips
were clear.
 The ST-CC circuit is opened.
 After the password setting (f738), the
password was input to f739 (password
verification).
 The inverter is in process of retry.
 A momentary stop occurred.
The motor speed is being detected.
 The deceleration stop during power failure
with  is activated.
 When a current flows at or higher than the over current stall
prevention level.
 When the overheat protection pre-alarm level is reached.
 When the cumulative amount of overload reaches 50% or
more of the overload trip value.
 When the main circuit element temperature reaches the
overload pre-alarm level.
 When a voltage is generated at or higher than the over voltage
stall prevention level.
 When a voltage is generated at or higher than the over voltage
stall prevention level.
 Even if it was lower than the over voltage stall prevention level,
when a voltage is generated at sharp increse.
 When the communication was broken off at or higher than the
over parameter f803 setting.
L-5
 Normal operation.
To be returned by pressing MODE key.
 Normal operation.
 Close the ST-CC circuit.
 If the password is correct, pass is
displayed and if it is incorrect, fail is
displayed.
 The inverter restarts automatically. Be
careful of the machine because it may
suddenly restart.
 To restart operation, power supply reset or
input an operation signal again.
