CAUTION

Do not connect the AC input to any of the U/T1, V/T2 or W/T3 terminals as it will damage the drive.

Multiple NFX9000 drives can be installed in one location. Please read the following prior to installation:

1. Follow all national and local electrical, construction and safety codes during installation.

2. Ensure the appropriate protective devices (circuit breaker or fuses) are connected between the power supply and drive.

3. Make sure the leads are connected correctly and the drive is properly grounded. (Ground resistance should not exceed .1 Ω .)

4. Use ground leads that comply with AWG/MCM standards and keep them as short as possible.

5. For multiple drive installations, make sure to ground all units directly to a common ground terminal. The ground terminals may be connected in parallel as shown in

Figure 2-4 . (Ensure there are no ground loops.)

6. For normal operation, make sure drive output terminals U/T1, V/T2 and W/T3 are connected to motor terminals U, V and W (respectively). The motor will rotate counterclockwise as viewed from the shaft ends of the motor when a forward operation command is received. To reverse the direction of motor rotation, switch any two of the motor leads.

7. Make sure the power source is capable of supplying the correct voltage and required current to the drive.

8. Do not attach or remove wiring when power is applied to the drive.

9. Do not monitor the signals on the circuit board while the drive is in operation.

10. Route the power and control wires separately or at right angles to each other.

11. If required to reduce electro-magnetic interference (EMI), install the ﬁlter as close as possible to the U/T1, V/T2 or W/T3 side of the drive.

Note: Do not use a capacitor or L-C ﬁlter (inductance/capacitance) or an R-C ﬁlter

(resistance/capacitance).

12. When using a GFCI (ground fault circuit interrupt), select a current sensor with a minimum current of 200 mA and a minimum detection time of .1 second to avoid nuisance tripping.

Appendix A — Fault Codes

The NFX9000 drive has a comprehensive fault diagnostic system that includes several different alarms and fault messages. Once a fault is detected, the corresponding protective functions will be activated. The following faults are displayed on the AC drive digital keypad. The six most recent faults can be read on the digital keypad display by viewing Parameter 6-07 to Parameter 6-12.

Note: Faults can be cleared by pressing the RESET key on the keypad or Input Terminal.

Fault Name Fault Description Corrective Action

NFX9000 Adjustable Frequency Drives

oc Drive detects an abnormal increase in

current

ou Drive detects that DC bus voltage has

exceeded its maximum allowable value

oH Drive’s temperature sensor detects

excessive heat

Lu Drive detects that DC bus voltage has

fallen below its minimum value

oL1 Internal electronic overload trip 1. Check for a possible motor overload.

EF External terminal EF-GND goes from

OFF to ON

oL2 Motor overload 1. Check settings for parameters 6-03 to 6-05.

1. Make sure the motor’s horsepower corresponds to the drive’s output power.

2. Check the wiring connections between the drive and motor for possible short circuits.

Note: If there are any abnormal conditions when operating the drive after the short circuit is removed, consult Eaton.

3. Increase the acceleration time (parameters 1-09 and 1-11).

4. Check for possible excessive loading.

1. Make sure the input voltage falls within the drive’s input voltage rating range.

2. Check for possible voltage transients.

3. Increase the deceleration time. (Bus overvoltage may also be caused by motor regeneration.)

1. Ensure that the ambient temperature falls within the speciﬁed temperature range.

2. Make sure that the ventilation holes are not obstructed.

3. Remove any foreign objects on the heat-sink and check for possible dirty heat-sink ﬁns.

4. Provide enough spacing for adequate ventilation.

Make sure the input voltage falls within the drive’s input voltage rating range.

2. Check electronic thermal overload setting.

3. Increase motor capacity.

4. Reduce the current level so the drive’s output current does not exceed the value set by the Motor Rated Current, parameter 7-00.

When the EF-GND is closed, the output will be turned off (under N.O.E.F.)

2. Reduce the motor load.

3. Adjust the over-torque detection setting to an appropriate setting.

2. Make sure the communication protocol is properly set.

Disable the connection between external input terminal (BB) and the drive. The drive will begin to run again.

1. Check whether the motor is overloaded.

2. Reduce torque compensation setting set in parameter 7-02.

3. Increase the drive’s output capacity.

Note: The drive can withstand up to 150% of the rated current for a maximum of 60 seconds.
