1.4 Product Overview

1.4.1 Intended Use

The drive is an electronic motor controller intended for:

•

Regulation of motor speed in response to system feedback or to remote commands from external controllers. A power-drive system consists of the drive, the motor, and equipment driven by the motor.

•

System and motor status surveillance.

The drive can also be used for motor protection. Depending on the configuration, the drive can be used in standalone applications or form part of a larger appliance or installation. The VLT® Decentral Drive FCD 302 is designed for decentral mounting, for example, in the food and beverage industry, or for other

material handling applications. With the FCD 302, it is possible to reduce costs by placing the power electronics decentrally. Central panels are then rendered obsolete, saving cost, space, and effort for installation and wiring. The basic design is service-friendly with a pluggable electronic part and a flexible and spacious wiring box. It is easy to change electronics without the need for rewiring.

Installation environment: The drive is allowed for use in residential, industrial, and commercial environments in accordance with local laws and standards.

N O T I C E

RADIO INTERFERENCE

In a residential environment, this product can cause radio interference, in which case supplementary mitigation measures can be

required.

Take the necessary precautions.

Foreseeable misuse

Do not use the drive in applications which are non-compliant with specified operating conditions and environments. Ensure compliance with the conditions specified in 7.4.1 Environment.

2 Safety

2.1 Safety Precautions

W A R N I N G

HIGH VOLTAGE

AC drives contain high voltage when connected to AC mains input, DC supply, or load sharing. Failure to perform installation,

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

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

W A R N I N G

UNINTENDED START

When the drive is connected to the AC mains, the motor may start at any time, causing risk of death, serious injury, and equip-

ment 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 condition.

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.

W A R N I N G

DISCHARGE TIME

The drive contains DC-link capacitors, which can remain charged even when the drive is not powered. High voltage can be

present even when the warning indicator lights are off.

Failure to wait the specified time after power has been removed before performing service or repair work could result in death or

serious injury.

Stop the motor.

Disconnect AC mains, permanent magnet type motors, and remote DC-link supplies, including battery back-ups, UPS, and

DC-link connections to other drives.

Wait for the capacitors to discharge fully. The time for full discharge of the capacitors is minimum 4 minutes for VLT® Decen-

tral Drive FCD 302, 400 V AC, 0.37–3.0 kW (0.5–4.0 hp).

Before performing any service or repair work, use an appropriate voltage measuring device to make sure that the capacitors

are fully discharged.

Illustration 17: Parallel Connection of Motors

Problems can arise at start-up and at low RPM values when motor sizes differ widely. Motors of low rated motor power have a relatively high ohmic resistance in the stator. This high resistance calls for a higher voltage at start and at low RPM values. To resolve such a problem:

•

Reduce the load during start-up on the motor of lowest rated motor power.

•

Configure parallel connections only between motors of comparable rated motor power.

6.1 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.

6.2 Cleaning

The enclosure (IP66/NEMA type 4x indoor) provides protection against dirt and water ingress. The enclosure is suitable for cleaning methods and solvents used in food and beverage plants. Use the solvent concentration recommended by the manufacturer. Avoid high-pressure hot water cleaning at close proximity or of long duration, because this method of cleaning can damage gaskets and labels.

6.6 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.

•

6.8 List of Warnings and Alarms

The following warning and alarm information defines each warning or alarm condition, provides the probable cause for the condition, and entails a remedy or troubleshooting procedure.

6.8.1 WARNING/ALARM 4, Mains Phase Loss

Cause

A phase is missing on the supply side, or the mains voltage imbalance is too high. This message also appears for a fault in the input rectifier. Options are programmed in parameter 14-12 Function at Mains Imbalance.

Troubleshooting

•

Check the supply voltage and supply currents to the drive.

6.8.2 WARNING 5, DC Link Voltage High

Cause

The DC-link voltage (DC) is higher than the high-voltage warning limit. The limit depends on the drive voltage rating. The unit is still active.

6.8.3 WARNING 6, DC Link Voltage Low

Cause

The DC-link voltage (DC) is lower than the low voltage warning limit. The limit depends on the drive voltage rating. The unit is still active.

6.8.4 WARNING/ALARM 8, DC Undervoltage

Cause

If the DC-link voltage drops below the undervoltage limit, the drive checks for 24 V DC back-up supply. If no 24 V DC back-up supply is connected, the drive trips after a fixed time delay. The time delay varies with unit size.

Troubleshooting

•

Check that the supply voltage matches the drive voltage.

•

Troubleshooting

6.8.5 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.

6.8.6 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.

6.8.7 WARNING/ALARM 11, Motor Thermistor Overtemp

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.

6.8.8 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.

Troubleshooting

If the motor torque limit is exceeded during ramp-up, extend the ramp-up time.

•

If the generator torque limit is exceeded during ramp-down time, extend the ramp-down time.

•

If torque limit occurs while running, increase the torque limit. Make sure that the system can operate safely at a higher torque.

•

Check the application for excessive current draw on the motor.

Troubleshooting

6.8.9 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.

6.8.10 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.

6.8.11 ALARM 15, Hardware Mismatch

6.8.14 WARNING/ALARM 22, Hoist Mechanical Brake

Cause

The value of this warning/alarm shows the type of warning/alarm.

0 = The torque reference was not reached before timeout (parameter 2-27 Torque Ramp Up Time).

1 = Expected brake feedback was not received before timeout (parameter 2-23 Activate Brake Delay, parameter 2-25 Brake Release Time).

6.8.15 WARNING 23, Internal Fan Fault

Cause

The fan warning function is a protective function that checks if the fan is running/mounted. The fan warning can be disabled in parameter 14-53 Fan Monitor ([0] Disabled).

For drives with DC fans, a feedback sensor is mounted in the fan. If the fan is commanded to run and there is no feedback from the sensor, this alarm appears. For drives with AC fans, the voltage to the fan is monitored.

Troubleshooting

Check for proper fan operation.

•

Cycle power to the drive and check that the fan operates briefly at start-up.

•

Check the sensors on the control card.

•

6.8.16 WARNING 25, Brake Resistor Short Circuit

Cause

The brake resistor is monitored during operation. If a short circuit occurs, the brake function is disabled and the warning appears. The drive is still operational, but without the brake function.

Troubleshooting

•

Remove the power to the drive and replace the brake resistor (refer to parameter 2-15 Brake Check).

6.8.17 WARNING/ALARM 26, Brake Resistor Power Limit

Cause

The power transmitted to the brake resistor is calculated as a mean value over the last 120 s of run time. The calculation is based on the DC-link voltage and the brake resistor value set in parameter 2-16 AC Brake Max. Current. The warning is active when the dissipated braking power is higher than 90% of the brake resistor power. If option [2] Trip is selected in parameter 2-13 Brake Power Monitor- ing, the drive trips when the dissipated braking power reaches 100%.

6.8.18 WARNING/ALARM 27, Brake Chopper Fault

Cause

The brake transistor is monitored during operation, and if a short circuit occurs, the brake function is disabled, and a warning is issued. The drive is still operational, but since the brake transistor has short-circuited, substantial power is transmitted to the brake resistor, even if it is inactive.

Troubleshooting

Remove the power to the drive and remove the brake resistor.

N O T I C E

This parameter cannot be adjusted while the motor is running.

The AMA function optimizes dynamic motor performance by automatically optimizing the advanced motor parameters (parameter 1-30 Stator Resistance (Rs) to parameter 1-35 Main Reactance (Xh)) at motor standstill. Activate the AMA function by pressing [Hand On] after selecting [1] Enable complete AMA or [2] Enable re- duced AMA. After a normal sequence, the display reads Press [OK] to finish AMA. After pressing [OK], the drive is ready for operation.

Enable complete AMA

Performs AMA of the stator resistance Rs, the rotor resistance Rr, the stator leakage reactance X1, the rotor leakage reactance X2, and the main reactance Xh.

[2]

Enable reduced AMA

Performs a reduced AMA of the stator resistance Rs in the system only. Select this option if an LC filter is used between the drive and the motor.

VLT® Decentral Drive FCD 302

Operating Guide

Table 33: Parameter 1-29 Automatic Motor Adaptation (AMA)

Appendix

N O T I C E

For the best adaptation of the drive, run AMA on a cold motor.

N O T I C E

AMA cannot be performed while the motor is running.

N O T I C E

AMA cannot be performed on permanent magnet motors.

N O T I C E

It is important to set parameter group 1-* Motor Data correctly since these parameters form part of the AMA algorithm. An AMA

must be performed to achieve optimum dynamic motor performance. Depending on the power rating of the motor, it takes up

to 10 minutes.

To avoid generating external torque during AMA, disconnect the motor shaft from the application.
