- If the Motor Does Not Operate
- Direction of the Motor Rotation is Reversed
- Motor Does Not Produce Torque or Acceleration is Slow
- Motor Operates Faster than the Frequency Reference
- Slip Compensation Function has Low Speed Precision
- Low Speed Control Accuracy at High-Speed Rotation in Open Loop Vector Control Method
- Insufficient torque during Rotational Auto-Tuning in Flux Loop Vector
- Speed fluctuation during Rotational Auto-Tuning in Flux Loop Vector
- Motor Deceleration is Too Slow
- Motor Overheat
- Noise is Produced from an AM Radio or when the MxC is Started
- Ground Fault Interrupter Operates while the MxC is Running
- Mechanical Oscillation
- Torque Generated for the Motor is Insufficient (Insufficient Power)
- Motor Rotates Even When MxC Output is Stopped
- OV or OC is Detected when the Fan is Started or Stalls
- Output Frequency does not Reach the Specified Frequency Reference
