Corrective Action
The measured temperature around the drive is above the operating limit of the
drive.
Ensure the drive internal cooling fan is operating.
Ensure that the required space around the drive as shown in sections
Mechanical Dimensions and Weight on page 15 to Guidelines for Mounting
(IP66 Units) on page 21 has been observed, and that the cooling airflow
path to and from the drive is not restricted.
Increase the cooling airflow to the drive.
Reduce the effective switching frequency setting in parameter P2-24.
Reduce the load on the motor / drive.
The output torque limit has exceeded the drive capacity or trip threshold.
Reduce the motor load, or increase the acceleration time.
developed prior to releasing the motor holding brake is below the preset
threshold. Contact your local Emerson Sales Partner for further information on
using the PACMotion VFD in hoist applications.
Drive output fault.
Speed Error. The error between the measured encoder feedback speed or the
estimated rotor speed is greater than the pre-set limit allowed. In Hoist Mode
Operation, this protection is always active even if no encoder is fitted. The
motor speed deviates from the intended motor speed by an error greater than
that set in the limit parameter P6-07.
Measured motor stator resistance varies between phases. Ensure the motor
is correctly connected and free from faults. Check the windings for correct
resistance and balance.
Measured motor stator resistance is too large. Ensure the motor is correctly
connected and free from faults. Check that the power rating corresponds to
the power rating of the connected drive.
Measured motor inductance is too low. Ensure the motor is correctly
connected and free from faults.
Measured motor inductance is too large. Ensure the motor is correctly
connected and free from faults. Check that the power rating corresponds to
the power rating of the connected drive.
Measured motor parameters are not convergent. Ensure the motor is correctly
connected and free from faults. Check that the power rating corresponds to
the power rating of the connected drive.
Applies to Frame Size 8 drives only, indicates that the incoming power supply
phase sequence is incorrect. Any 2 phases may be swapped.
One of the motor output phases is not connected to the drive.
