 During acceleration: Motor starts deceleration when current exceeding the value set in
F60 flows.
 During constant run: Motor decelerates when current exceeding the value set in F60
flows.
 During deceleration: Motor deceleration 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 still can be monitored in these codes though F59 is not selected (000).
 F59: Stall prevention can be set as the table below.
