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 and Reset
Action level
Pr.07-29
100% of Pr.07-29 = the maximum limit of the slip frequency (Pr.10-29)
Action time Pr.07-30
Fault treatment parameter
Pr.07-31
0: Warn and continue operation
1: Fault and ramp to stop
2: Fault and coast to stop
3: No warning
Reset method
Auto
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.
Hand When Pr.07-31=1 or 2, oSL is an error, and it needs to reset manually.
Reset condition Immediately reset
Record Pr.07-31=1 or 2, oSL is “Fault”, and will be recorded.
Cause Corrective Actions
Any of the motor parameters in
parameter group 5 may be
incorrect
Check the motor parameters
Overload Decrease the load
Any of the setting value of
Pr.07-29, 07-30, and 10-29 is
improper
Check the setting of oSL protection function related parameters

Electric valve switch
error (ryF)
Electric valve switch error when executing Soft Start
Action and Reset
Action level Hardware detection (Frame D and above)
Action time Immediately act
Fault treatment parameter N/A
Reset method Manual reset
Reset condition Reset when the electric valve switch is correctly closed
Record Yes
Cause Corrective Actions
The input power is abnormal
Check if the power is shut down during the drive operation?
Check if the three-phase input power is normal.
Malfunction caused by interference Verify the wiring/grounding of the main circuit to prevent interference.
Hardware failure
Cycle the power after checking the power. If ryF error still exists, return to the
factory for repair.
