Phase lacked
Phase loss of power input
Action and Reset
Action level DC bus is lower than [PROT-06] and DC bus ripple is higher than [PROT-27]
Action time Immediately
Related parameters [PROT-28] determines fault function. [PROT-26] is period between checks.
Reset method Manually
Reset condition Immediately reset when DC bus is higher than [PROT-06]
Recorded Yes
Possible Causes Corrective Action
• Phase loss of input power
• Single phase power input to three-
phase model
• Power voltage changes
• Loose wiring terminal of input power
• The input cable of three-phase power
is cut off
• Input power voltage changes too
much
• Unbalanced three-phase of input
power
• Correctly install the wiring of the main circuit power.
• Choose the model whose power matches the voltage.
• If the main circuit power works normally, verify the main circuit. Cycle the power after checking the
power, if OrP error still exists, call Technical Support.
• Tighten the terminal screws according to the torque described in the user manual.
• Wire correctly. Replace the cut off cable.
• Verify the setting value for
IPO Check Time [PROT-26] and IPO Ripple [PROT-27] .
• Check the power three-phase status.
Fault Display Description
oSL (63)
Over slip error
On the basis of the maximum slip limit set via
[MOTOR-19]
, the speed deviation is abnormal. When the motor drive out -
puts at constant speed, F > H or F < H exceeds the level set via
[MOTOR-19]
, and it exceeds the time set via
[MOTOR-20]
,
oSL shows. oSL occurs in induction motors only.
Action and Reset
Action level 100% of
[MOTOR-19]
= the maximum limit of the slip frequency
Action time
[MOTOR-20]
Related parameters Fault/Warning based on
[MOTOR-21]
Reset method
Auto
[MOTOR-21]
= 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
[MOTOR-19]
anymore.
Manually When
[MOTOR-21]
= 1 or 2, oSL is an error
Reset condition Immediately
Recorded
[MOTOR-21]
= 1 or 2, oSL is “Fault” and will be recorded
Possible Causes Corrective Action
• Any of the motor parameters may be
incorrect
• Overload
• Improper setup of feature
• Verify the motor parameters
• Decrease the load
• Verify the settings of
[MOTOR-18]
through
[MOTOR-21]
