Description
Pr.22 OL Trip Time
the overload trip time (OL Trip Time), the inverter output is either blocked
according to the preset mode from Pr. 17 or slows to a stop after
deceleration.
Note
Overload warnings warn of an overload before an overload fault trip occurs. The overload
warning signal may not work in an overload fault trip situation, if the overload warn level (OL
Warn Level) and the overload warn time (OL Warn Time) are set higher than the overload trip
level (OL Trip Level) and overload trip time (OL Trip Time).
Stall Prevention and Flux Braking
The stall prevention function is a protective function that prevents motor stall caused by
overloads. If a motor stall occurs due to an overload, the inverter operation frequency is
adjusted automatically. When stall is caused by overload, high currents are induced in the
motor may cause motor overheat or damage the motor and interrupt operation of the motor-
driven devices.
To protect the motor from overload faults, the inverter output frequency is adjusted
automatically, based on the size of load.
