Over-slip
(oSL)
The slip is abnormal. By using the maximum slip
(Pr.10-29) as the base, when the drive outputs at
constant speed, and the F > H or F < H exceeds
Pr.07-29 level and Pr.07-30 setting time, oSL occurs.
oSL occurs only when using a general induction motor.

3: No warning
Reset method
Auto
When Pr.07-31＝0, oSL is a “Warming”
When the drive outputs at constant speed, and the F > H or F <
H no
longer exceeds the Pr.07-29 level, the oSL warning is
automatically
cleared.
