Fault Name
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
Over slip error (oSL)
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
Pr. 07-29
100% of Pr. 07-29 = the maximum limit of the slip frequency (Pr. 10-29)
Pr. 07-30
Pr. 07-31
0: Warn and continue operation
1: Warn and ramp to stop
2: Warn and coast to stop
3: No warning
Pr. 07-31=0 is a warning.
When the motor drive outputs at constant speed, and F>H or F<H
Auto
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.
Immediately reset
Pr. 07-31=1 or 2, oSL is "Fault", and will be recorded.
Check the motor parameters
Decrease the load
Check the setting of oSL protection function related parameters
Fault Name
Electric valve switch
Electric valve switch error when executing Soft Start
error (ryF)
Action and Reset
Hardware detection (Frame D and above)
Immediately act
N/A
Manual reset
Reset when the electric valve switch is correctly closed
Yes
Check if the power is shut down during the drive operation?
Check if the three-phase input power is normal.
Cycle the power after checking the power. If ryF error still exists, return to the
factory for repair.
