Over slip error (oSL)
On the basis of the maximum slip limit set via Pr.10-29, the speed deviation is abnormal. When the motor drive outputs at constant speed, F > H or F < H exceeds the level set via Pr.07-29, and it exceeds the time set via Pr.07-30, oSL shows. oSL occurs in induction motors only.
Action condition - Pr.07-29 100% of Pr.07-29 = the maximum limit of the slip frequency (Pr.10-29).
When Pr.07-31 = 1 or 2, oSL is an error, and it needs to reset manually.
Pr.07-31 = 0 is a warning.
When the motor drive outputs at constant speed, and F > H or F < H does not exceed the level set via Pr.07-29 anymore, oSL warning will be cleared automatically.
Check the motor parameters.
