Look for auxiliary equipment, switches, disconnects, or input fuses/circuit breakers residing on the input power side of the drive, or output side to the motor. Ensure that they are ready for full-speed operation.

Check the function and installation of any sensors used for feedback to the drive.

Remove any power factor correction capacitors on the motor.

Adjust any power factor correction capacitors on the mains side and ensure that they are dampened.

Cable routing

Ensure that the motor wiring and control wiring are separated, shielded, or in 3 separate metallic conduits for high-frequency interference isolation.

4.7.2 Mechanical Brake Control

In hoisting/lowering applications, it is necessary to control an electro-mechanical brake.

•

Control the brake using any relay output or digital output (terminal 27 or 29).

•

Keep the output closed (voltage-free) as long as the drive is unable to keep the motor at standstill, for example due to the load being too heavy.

•

Select [32] Mechanical brake control in parameter group 5-4* Relays for applications with an electromechanical brake.

•

The brake is released when the motor current exceeds the value in parameter 2-20 Release Brake Current.

•

The brake is engaged when the output frequency is less than the frequency set in parameter 2-21 Activate Brake Speed [RPM] or parameter 2-22 Activate Brake Speed [Hz], and only if the drive carries out a stop command.

If the drive is in alarm mode or in an overvoltage situation, the mechanical brake immediately closes.

N O T I C E

The drive is not a safety device. It is the responsibility of the system designer to integrate safety devices according to relevant

national crane/lift regulations.

√

Control wiring

Check for broken or damaged wires and loose connections.

Check that the control wiring is isolated from power and motor wiring for noise immunity.

Check the voltage source of the signals, if necessary.

The use of shielded cable or twisted pair is recommended. Ensure that the shield is terminated correctly.

Cooling clearance

Ensure that the top and bottom clearance is adequate to ensure proper airflow for cooling, see 3.3.1

Cooling.

Ambient conditions

Check that requirements for ambient conditions are met.

Fusing and circuit breakers

Check for proper fusing or circuit breakers.

Check that all fuses are inserted firmly and are in operational condition, and that all circuit breakers are in the open position.

Grounding

Check for sufficient ground connections and ensure that those connections are tight and free of oxidation.

Grounding to conduit, or mounting the back panel to a metal surface, is not a suitable grounding.

Input and output power wiring

Check for loose connections.

Check that the motor and mains cables are in separate conduit or separated shielded cables.

Panel interior

Inspect that the unit interior is free of dirt, metal chips, moisture, and corrosion.

Check that the unit is mounted on an unpainted metal surface.

Switches

Ensure that all switch and disconnect settings are in the proper positions.

Vibration

Check that the unit is mounted solidly, or that shock mounts are used, as necessary.

Check for an unusual amount of vibration.

See chapter Safety for general safety instructions.

W A R N I N G

HAZARDOUS VOLTAGE

AC drives contain hazardous voltage when connected to the AC mains or connected on the DC terminals. Failure to perform

installation, start-up, and maintenance by skilled personnel can result in death or serious injury.

Only skilled personnel must perform installation, start-up, and maintenance.

N O T I C E

The front covers with warning signs are an integrated part of the drive and considered safety covers. The covers must be in place

before applying power and at all times.

5.1.1 Before Applying Power

Procedure

Close the safety cover properly.

Check that all cable glands are firmly tightened.

Ensure that input power to the unit is off and locked out. Do not rely on the drive disconnect switches for input power isolation.

Verify that there is no voltage on input terminals L1 (91), L2 (92), and L3 (93), phase-to-phase, and phase-to-ground.

Verify that there is no voltage on output terminals 96 (U), 97 (V), and 98 (W), phase-to-phase, and phase-to-ground.

Confirm continuity of the motor by measuring Ω values on U–V (96–97), V–W (97–98), and W–U (98–96).

Check for proper grounding of the drive and the motor.

Inspect the drive for loose connections on the terminals.

Confirm that the supply voltage matches the voltage of the drive and the motor.

6.1.15 Wiring Configuration for Torque and Stop Limit

In applications with an external electro-mechanical brake, such as hoisting applications, it is possible to stop the drive via a standard stop command and simultaneously activate the external electro-mechanical brake. Programming of these drive connections is shown in Illustration 17.

If a stop command is active via terminal 18 and the drive is not at the torque limit, the motor ramps down to 0 Hz. If the drive is at the torque limit and a stop command is activated, the system activates terminal 29 output (programmed to [27] Torque limit & stop). The signal to terminal 27 changes from logic 1 to logic 0 and the motor starts to coast. This process ensures that the hoist stops even if the drive itself cannot handle the required torque, for example due to excessive overload.

To program the stop and torque limit, connect to the following terminals:

•

Start/stop via terminal 18 (Parameter 5-10 Terminal 18 Digital Input [8] Start).

•

Quick stop via terminal 27 (Parameter 5-12 Terminal 27 Digital Input [2] Coasting Stop, Inverse).

•

Terminal 29 output (Parameter 5-02 Terminal 29 Mode [1] Terminal 29 Mode Output and parameter 5-31 Terminal 29 Digital Output [27] Torque limit & stop).

7 Maintenance, Diagnostics, and Troubleshooting

7.1 Maintenance and Service

Under normal operating conditions and load profiles, the drive is maintenance-free throughout its designed lifetime. To prevent breakdown, danger, and damage, examine the drive for loose terminal connections, excessive dust buildup, and so on, at regular intervals. Replace worn or damaged parts with Danfoss authorized parts. For service and support, contact the local Danfoss supplier.

W A R N I N G

UNINTENDED START

When the drive is connected to the AC mains, DC supply, or load sharing, the motor may start at any time, causing risk of death,

serious injury, and equipment or property damage. The motor may start by activation of an external switch, a fieldbus command,

an input reference signal from the LCP or LOP, via remote operation using MCT 10 Set-up software, or after a cleared fault condi-

tion.

Press [Off] on the LCP before programming parameters.

Disconnect the drive from the mains whenever personal safety considerations make it necessary to avoid unintended motor

start.

Check that the drive, motor, and any driven equipment are in operational readiness.

7.2 Warning and Alarm Types

Warnings

A warning is issued when an alarm condition is impending, or when an abnormal operating condition is present and may result in the drive issuing an alarm. A warning clears by itself when the abnormal condition ceases.

Alarms

An alarm indicates a fault that requires immediate attention. The fault always triggers a trip or a trip lock. Reset the system after an alarm.

Trip

An alarm is issued when the drive is tripped, meaning that the drive suspends operation to prevent damage to the drive or system. The motor coasts to a stop. The drive logic continues to operate and monitor the drive status. After the fault condition is remedied, the drive can be reset. It is then ready to start operation again.

Trip lock

Input power is cycled. The motor coasts to a stop. The drive continues to monitor the drive status. Remove input power to the drive, correct the cause of the fault, and reset the drive.

Resetting the drive after a trip/trip lock

A trip can be reset in any of 4 ways:

•

Press [Reset] on the LCP.

•

Digital reset input command.

•

Serial communication reset input command.

•

Auto reset.

Troubleshooting

7.4.9 WARNING/ALARM 9, Inverter Overload

Cause

The drive has run with more than 100% overload for too long and is about to cut out. The counter for electronic thermal inverter protection issues a warning at 98% and trips at 100% with an alarm. The drive cannot be reset until the counter is below 90%.

Troubleshooting

•

Compare the output current shown on the LCP with the drive rated current.

•

Compare the output current shown on the LCP with the measured motor current.

•

Show the thermal drive load on the LCP and monitor the value. When running above the drive continuous current rating, the counter increases. When running below the drive continuos current rating, the counter decreases.

7.4.10 WARNING/ALARM 10, Motor Overload Temperature

Cause

According to the electronic thermal protection (ETR), the motor is too hot. Select 1 of these options:

•

The drive issues a warning or an alarm when the counter is >90% if parameter 1-90 Motor Thermal Protection is set to warning options.

•

The drive trips when the counter reaches 100% if parameter 1-90 Motor Thermal Protection is set to trip options.

The fault occurs when the motor runs with more than 100% overload for too long.

Troubleshooting

Check for motor overheating.

•

Check if the motor is mechanically overloaded.

•

Check that the motor current set in parameter 1-24 Motor Current is correct.

•

Ensure that the motor data in parameters 1-20 to 1-25 is set correctly.

•

If an external fan is in use, check that it is selected in parameter 1-91 Motor External Fan.

•

Running AMA in parameter 1-29 Automatic Motor Adaptation (AMA) tunes the drive to the motor more accurately and reduces thermal loading.

7.4.11 WARNING/ALARM 11, Motor Thermistor Overtemp

Cause

The motor thermistor indicates that the motor temperature is too high.

Troubleshooting

Check for motor overheating.

•

Check that the thermistor is securely connected.

•

Check if the motor is mechanically overloaded.

•

When using terminal 53 or 54, check that the thermistor is connected correctly between either terminal 53 or 54 (analog voltage

• input) and terminal 50 (+10 V supply). Also check that the terminal switch for 53 and 54 is set for voltage. Check that parameter 1-93 Thermistor Resource selects 53 or 54.

When using terminal 18, 19, 31, 32, or 33 (digital inputs), check that the thermistor is connected correctly between the digital

• input terminal used (digital input PNP only) and terminal 50. Select the terminal to use in parameter 1-93 Thermistor Resource.

7.4.12 WARNING/ALARM 12, Torque Limit

Cause

The torque has exceeded the value in parameter 4-16 Torque Limit Motor Mode or the value in parameter 4-17 Torque Limit Generator Mode. Parameter 14-25 Trip Delay at Torque Limit can change this warning from a warning-only condition to a warning followed by an alarm.

VLT® AutomationDrive FC 301/FC 302

Maintenance, Diagnostics, and

Operating Guide

Troubleshooting

•

Troubleshooting

7.4.13 WARNING/ALARM 13, Overcurrent

Cause

The inverter peak current limit (approximately 200% of the rated current) is exceeded. The warning lasts approximately 1.5 s, then the drive trips and issues an alarm. Shock loading or quick acceleration with high-inertia loads can cause this fault. If the acceleration during ramp-up is quick, the fault can also appear after kinetic back-up. If extended mechanical brake control is selected, a trip can be reset externally.

Troubleshooting

•

Remove power and check if the motor shaft can be turned.

•

Check that the motor size matches the drive.

•

Check that the motor data is correct in parameters 1-20 to 1-25.

7.4.14 ALARM 14, Earth (Ground) Fault

Cause

There is current from the output phase to ground, either in the cable between the drive and the motor, or in the motor itself. The current transducers detect the ground fault by measuring current going out from the drive and current going into the drive from the motor. Ground fault is issued if the deviation of the 2 currents is too large. The current going out of the drive must be the same as the current going into the drive.

Troubleshooting

•

Remove power to the drive and repair the ground fault.

•

Check for ground faults in the motor by measuring the resistance to ground of the motor cables and the motor with a megohmmeter.

•

Reset any potential individual offset in the 3 current transducers in the drive. Perform a manual initialization or perform a complete AMA. This method is most relevant after changing the power card.

Mains voltage low/mains dropout: During low mains voltage or a mains dropout, the drive continues until the DC-link voltage drops below the minimum stop level, which typically corresponds to 15% below the drive's lowest rated supply voltage. Power-up and full torque cannot be exptected at mains voltage lower than 10% below the drive's lowest rated supply voltage.

The unit is suitable for use on a circuit capable of delivering not more than 100000 RMS symmetrical Amperes, 240/500/600/690 V maximum.

Specifications

Terminals 27 and 29 can also be programmed as output.

Except STO input terminal 37.

8.6.2 STO Terminal 37 (Terminal 37 is Fixed PNP Logic)

All digital inputs are galvanically isolated from the supply voltage (PELV) and other high-voltage terminals. See 4.7.1 Safe Torque Off (STO) for further information about terminal 37 and Safe Torque Off. When using a contactor with a DC coil inside in combination with STO, it is important to make a return way for the current from the

coil when turning it off. This can be done by using a freewheel diode (or, alternatively, a 30 V or 50 V MOV for quicker response time) across the coil. Typical contactors can be bought with this diode.

8.7 Fuses and Circuit Breakers

8.7.1 Fuse Recommendations

Fuses ensure that possible damage to the drive is limited to damage inside the unit. Danfoss recommends fuses and/or circuit breakers on the supply side as protection. For further information, see Application Note Fuses and Circuit Breakers.

N O T I C E

Use of fuses on the supply side is mandatory for IEC 60364 (CE) and NEC 2009 (UL) compliant installations.

Recommendations

•

gG type fuses.

•

Moeller type circuit breakers. For other circuit breaker types, ensure that the energy into the drive is equal to or lower than the energy provided by Moeller types.

For further information, see Application Note Fuses and Circuit Breakers. The recommended fuses in 8.7.2 CE Compliance and 8.7.3 UL Compliance are suitable for use on a circuit capable of 100000 A

(symmetrical), depending on the drive voltage rating. With the proper fusing, the drive short circuit current rating (SCCR) is 10000 A

8.7.3 UL Compliance

Fuse classification for UL Compliance

N O T I C E

UL COMPLIANCE

To comply with NEC 2017, it is mandatory to use fuses or circuit breakers. Danfoss recommends using a selection of the fuses

listed in the following tables. These fuses are suitable for use on a circuit capable of delivering 100000 A

480 V, 500 V, or 600 V depending on the drive voltage rating. With the proper fusing, the drive short circuit current rating (SCCR)

is 10000 A

For semiconcutor fuse types, the drive controller and the overcurrent protection device must be integrated within the same overall assembly.
