[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.
Error code Name

Overcurrent pre-alarm

Overvoltage pre-alarm

Overload pre-alarm

Overheat pre-alarm

Communication pre-alarm
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.
Description
 Auto-tuning in process
 The input terminal was switched to sink
logic of external power supply input
(+24V).
 The input terminal was switched to
source logic.
 The input terminal was switched to sink
logic.
 After the password setting (f738), the
password was input to f739 (password
verification).
 The EASY key was pushed in the
standard monitor mode.
 Power was supplied to the inverter at first
time
 Set the parameter set to 0.
 Set the parameter typ to 13.
 No new record of past trip, after past trips
were clear.
 The detailed information of past trip is
read by pushing the center of setting dial
during blinking nerr ⇔ number.
Description
 When a current flows at or higher than the over current stall
prevention 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 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 the overheat protection pre-alarm level is reached.
 When the communication was broken off at or higher than the
over parameter f803 setting.

Remedies
 Normal if it the message disappears after a few
seconds.
 After removing connection of the control circuit
terminals reset or turn the power off and then back
on again. This switches the logic.
 If the password is correct, pass is displayed and
if it is incorrect, fail is displayed.
 When easy is displayed, setting mode becomes
easy setting mode. When std is displayed, it
becomes standard setting mode.

Set a region setting by using setting dial.
Refer to section 3.1.
 Normal operation.
 Normal operation.
To be returned by pressing MODE key.
Remedies
Same as  (overcurrent)
Same as  (overvoltage)
Same as  (overload)
Same as  (overheat)
Same as err5 (communication
fault)
