The user can identify drive faults via fault codes on the display. OCd is the code for the overcurrent at deceleration fault. This fault is caused by either an overcurrent condition that occurred while the drive was decelerating, or a too-short deceleration time. In order to correct this fault, increase the deceleration time. OF is the code for the overfrequency fault. This fault is caused by the drive exceeding the maximum allowable output frequency, the regenerating energy is too high, the stability or slip compensation circuit is adding frequency reference, the motor is too small, and/or if H.016 is ON, the searching current is too high. In order to correct this fault, increase deceleration time, check the slip compensation, and/or check the motor size v. the power module size. OH is the code for the drive overtemperature fault. This fault is caused by a cooling fan failure. In order to correct this fault, check the ambient temperature, the cooling fan, and the minimum clearances around the drive.
