During acceleration: Motor acceleration ramp is stopped when current exceeds the value set in
F60.

During constant run: Motor decelerates when current exceeds the value set in F60.

During deceleration: Motor deceleration ramp is stopped when inverter DC link voltage rises
above a certain voltage level.

F60: The value is set as the percent of motor rated current (H33).

I54, I55: Inverter outputs signals through multi-function output terminal (MO) or relay output
(3ABC) or external sequence when stall prevention function is activated. Motor stall status can be
monitored setting F59 different from (000).
