• Function
Trips the inverter or issues an alarm if the total time for which torque is above the level set with
/
reaches the time set with
. Trip information is displayed as “

(No trip) ··············· No tripping (FL is not active).
=
(Tripping) ············ The inverter will trip (the failure signal FL will be activated) if a torque larger than
(during power running) or
(during regeneration) passes for a time
longer than the time set with

6.33.11 Cooling fan control selection
: Cooling fan control selection
• Function
With this parameter, you can set the condition of cooling fan so that it operates only when the inverter
requires cooling, and thus it can be used for a longer period.
=
: Automatic control of cooling fan, enabled. Operates only when the inverter is in operation.
=
: Automatic control of cooling fan, disabled. The cooling fan always operates when the inverter is
energized.
