Hazardous High Voltage

Motor control equipment and electronic controllers are connected to hazardous line voltages. When servicing drives and electronic controllers, there may be exposed components with housings or protrusions at or above line potential. Extreme care should be taken to protect against shock.

●

Stand on an insulating pad and make it a habit to use only one hand when checking components.

●

Always work with another person in case an emergency occurs.

●

Disconnect power before checking controllers or performing maintenance.

●

Be sure equipment is properly grounded.

●

Wear safety glasses whenever working on electronic controllers or rotating machinery.

WARNING

Power and Control Wiring

Basic Wiring

●

Use power terminals R/L1 and S/L2 for single-phase connection to models: NFXF25A0-1, NFXF50A0-1, NFXF25A0-2, NFXF50A0-2 or NFX001A0-2.

●

Use power terminals R/L1, S/L2 and T/L3 for three-phase connection to models: NFXF25A0-2, NFXF50A0-2, NFX001A0-2 or NFX002A0-2.

Wiring Notes

–

Ensure that all screws are tightened to the proper torque rating.

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 .1Ω.)

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 below. (Ensure there are no ground loops.)

Ground Terminals Connected in Parallel

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.

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.

08 0 ASCII mode:

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.

1. Make sure the insulation is adequate at the output line.

2. Decrease the torque boost setting in parameter 7-02.

3. Increase the acceleration time.

4. Replace the drive with one that has a higher output capacity (next level hp).
