1: Decel Time 1 - In order to
avoid stalling during heavy
loading, the Drive will
decelerate at Decel time 1
(C1-02) if the output current
exceeds the level set by
L3-05
L3-06. Once the current
level drops below the L3-06
level, the Drive will

2: Decel Time 2 - Same as
setting 1 except the Drive
decelerates at Decel Time 2
(C1-04).
When output frequency is 6Hz
or less, stall prevention during
run is disabled regardless of
