4.2 EMC Compliant Installation

4.2.1 General Aspects of EMC Emissions

The frequency converter, motor cable and the motor generate airborne interference in the range 30 MHz to 1 GHz. Capacitive currents in the motor cable coupled with a high dU/dt from the motor voltage generate leakage currents.

Use screened motor cable to reduce radiated interference. Connect the motor cable screen to the frequency converter enclosure as well as to the motor enclosure. Use integrated screen clamps to avoid twisted screen ends (pigtails).

To reduce the interference level from the entire system (unit + installation), make motor and brake cables as short as possible. Avoid placing cables with a sensitive signal level alongside motor and brake cables. Especially control electronics generate radio interference higher than 50 MHz (airborne).

Table 4.1

Illustration 4.9 Situation that Generates Leakage Currents

Ensure that screen currents can be conveyed back to the frequency converter. Also, ensure good electrical contact from the mounting plate through the mounting screws to the frequency converter chassis.

NOTICE

When unscreened cables are used, some emission requirements are not complied with, although the immunity requirements are observed.

sinusoidal current is transformed with a Fourier analysis and split into sine-wave currents with different frequencies,

that is, different harmonic currents In with 50 Hz basic frequency:

Hz 50 250 350

Table 4.4 Harmonic Currents

The harmonics do not affect the power consumption directly, but increase the heat losses in the installation (transformer, cables). So, in plants with a high percentage of rectifier load, maintain harmonic currents at a low level to avoid overload of the transformer and high temperature in the cables.

Illustration 4.10 Harmonic Currents

NOTICE

Some of the harmonic currents might disturb communication equipment connected to the same transformer or cause resonance with power-factor correction batteries.

To ensure low harmonic currents, the frequency converter is equipped with intermediate circuit coils as standard. This normally reduces the input current I

by 40%.

Converter

5.2.1 Applying Power Procedure

CAUTION

HIGH VOLTAGE!

If input and output connections have been connected

improperly, there is potential for high voltage on these terminals. Power cables for multiple motors run improperly in same conduit cause a risk of leakage current charging capacitors within the frequency converter. The risk is also present even when the frequency converter is disconnected from mains input. For initial start-up, make no assumptions about power components. Follow pre-start procedures. Failure to follow pre-start procedures could result in personal injury or damage to equipment.

1. Input power to the unit must be OFF and locked out. Do not rely on the frequency converter disconnect switches for input power isolation.

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

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

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

5. Check for proper grounding of the frequency converter as well as the motor.

6. Inspect the frequency converter for loose connections on terminals.

7. Confirm that the supply voltage matches voltage of frequency converter and motor.

WARNING

HIGH VOLTAGE!

Frequency converters contain high voltage when connected to the energised DC bus. Only qualified personnel should install, start up and maintain the freqeuncy converters. Failure to let qualified personnel install, start up and maintain the frequency converters could result in death or serious injury.

WARNING

UNINTENDED START!

When the frequency converter is connected to the energised DC bus, the motor may start at any time. The frequency converter, motor, and any driven equipment must be in operational readiness. Failure to be in operational readiness when the frequency converter is connected to the energised DC bus could result in death, serious injury, equipment, or property damage.

1. Confirm that input voltage is balanced within 3%. If not, correct input voltage imbalance before proceeding. Repeat procedure after voltage correction.

2. Ensure optional equipment wiring, if present, matches installation application.

3. Ensure that all operator devices are in the OFF position. Panel doors closed, or a cover mounted.

4. Apply power to the unit. DO NOT start the frequency converter now. For units with a disconnect switch, turn to the ON position to apply power to the frequency converter.

NOTICE

Before applying power to the unit, inspect the entire installation, see chapter 4.10.1 Installation Check List

7 Functions

7.1 Brake Functions

7.1.1 Introduction

Brake function is applied for braking the load on the motor shaft, either as dynamic brake or static brake.

7.1.1.1 Mechanical Holding Brake

A mechanical holding brake mounted directly on the motor shaft normally performs static braking. In some applications, the static holding torque works as static holding of the motor shaft (synchronous permanent motors). A PLC or a digital output from the frequency converter (relay or solid state) controls the holding brake.

NOTICE

When the holding brake is included in a safety chain: A frequency converter cannot provide a safe control of a mechanical brake. A redundancy circuitry for the brake control must be included in the total installation.

7.1.1.2 Dynamic Brake

Load cycle 2 Motor current 3 Motor operation 4 Generator operation

7 7

Establish a dynamic brake by using a brake resistor. A brake IGBT keeps the overvoltage below a certain threshold by directing the brake energy from the motor to the connected brake resistor.

Brake Resistor Requirements

7.1.2

A brake resistor can handle regenerative braking and ensure that energy is absorbed in the brake resistor and not in the frequency converter. For more information, see Brake Resistor Design Guide.

The amount of kinetic energy transferred to the resistor in each braking period can be calculated based on the cycle time and braking time (intermittent duty cycle).

Calculate the intermittent duty cycle for the resistor as follows:

Duty cycle = tb/T

T = cycle time in s tb is the braking time in s (of the cycle time)

Illustration 7.1 Intermittent Duty Cycle

Cycle time (s) 120 Braking duty cycle at 100% torque Continuous Braking duty cycle at over torque (150/160%) 40%

Table 7.1 Braking at High Overload Torque Level

380-400 V PK37-P75K

If a 10% duty cycle is applied, the brake resistors are able to absorb brake power for 10% of the cycle time. The remaining 90% of the cycle time is used on dissipating excess heat. Danfoss offers brake resistors with duty cycle of 5%, 10% and 40%.

NOTICE

Make sure that the resistor is designed to handle the required braking time.

The max. permissible load on the brake resistor is stated as a peak power at a given intermittent duty cycle and can be calculated as:

FIRE HAZARD!

Do not touch the brake resistor as it can get hot while/ after braking. To avoid fire, place the brake resistor in a secure environment. Failure to follow these guidelines can cause personal injury and property/equipment damage.

NOTICE

Do not apply resistor brake circuit resistances higher than recommended by Danfoss. If a brake resistor with a higher ohmic value is selected, the 160% braking torque may not be achieved as the frequency converter may cut out for safety reasons.

NOTICE

If there is a short circuit in the brake transistor, prevent power dissipation in the brake resistor by using a mains switch or contactor to disconnect the mains for the frequency converter. (The frequency converter can control the contactor).

No motor has been connected to the output of the frequency converter.

WARNING/ALARM 4, Mains phase loss

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 on the frequency converter. Options are programmed at 14-12 Function at Mains Imbalance.

Troubleshooting

Check the supply voltage and supply currents to the frequency converter.

WARNING 5, DC link voltage high

The intermediate circuit voltage (DC) is higher than the high-voltage warning limit. The limit is dependent on the frequency converter voltage rating. The unit is still active.

WARNING 6, DC link voltage low

The intermediate circuit voltage (DC) is lower than the lowvoltage warning limit. The limit is dependent on the frequency converter voltage rating. The unit is still active.

WARNING/ALARM 7, DC overvoltage

If the intermediate circuit voltage exceeds the limit, the frequency converter trips after a time.

Troubleshooting

Connect a brake resistor Extend the ramp time Change the ramp type Activate the functions in 2-10 Brake Function Increase 14-26 Trip Delay at Inverter Fault If the alarm/warning occurs during a power sag,

use kinetic back-up (14-10 Mains Failure)

WARNING/ALARM 8, DC under voltage

If the DC-link voltage drops below the undervoltage limit, the frequency converter checks if a 24 V DC backup supply is connected. If no 24 V DC backup supply is connected, the frequency converter trips after a fixed time delay. The time delay varies with unit size.

Troubleshooting

Check that the supply voltage matches the frequency converter voltage.

Perform input voltage test. Perform soft charge circuit test.

WARNING/ALARM 9, Inverter overload

The frequency converter is about to cut out because of an overload (too high current for too long). The counter for electronic, thermal inverter protection issues a warning at 98% and trips at 100%, while giving an alarm. The frequency converter cannot be reset until the counter is below 90%. The fault is that the frequency converter has run with more than 100% overload for too long.

Troubleshooting

Compare the output current shown on the LCP with the frequency converter rated current.

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

Display the thermal drive load on the LCP and monitor the value. When running above the frequency converter continuous current rating, the counter increases. When running below the

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, extend the ramp down time.

If torque limit occurs while running, possibly 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.

WARNING/ALARM 13, Over current

The inverter peak current limit (approximately 200% of the rated current) is exceeded. The warning lasts about 1.5 s, then the frequency converter 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, trip can be reset externally.

Troubleshooting

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

Check that the motor size matches the frequency converter.

Check parameters 1-20 to 1-25 for correct motor data.

ALARM 14, Earth (ground) fault

There are current from the output phases to ground, either in the cable between the frequency converter and the motor or in the motor itself.

Troubleshooting

Remove power to the frequency converter and repair the ground fault.

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

WARNING 25, Brake resistor short circuit

The brake resistor is monitored during operation. If a short circuit occurs, the brake function is disabled and the warning appears. The frequency converter is still operational, but without the brake function. Remove power to the frequency converter and replace the brake resistor.

WARNING/ALARM 26, Brake resistor power limit

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 intermediate circuit voltage and the brake resistance value. The warning is active when the dissipated braking is higher than 90% of the brake resistance power.

WARNING

If the brake transistor is short-circuited, there is a risk of substantial power being transmitted to the brake resistor.

WARNING/ALARM 27, Brake chopper fault

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

Remove power to the frequency converter and remove the brake resistor.

This alarm/warning could also occur if the brake resistor overheats.

WARNING/ALARM 28, Brake check failed

The brake resistor is not connected or not working.

VLT® Lift Drive LD 302

9.1 Main Contactors

Prolong the life time of the main contactors by only switching off the main contactors if the lift motor is deenergised (no current load). For load-free switching of the main contactors, control of the lift should proceed as illustrated in Illustration 9.1 and Illustration 9.2.

9.2 Operation with Absolute Encoder (SSI/ EnDat)

For running PM-motors with frequency converters, it is necessary to know the exact rotor position. Usually, the rotor position is determined by using a single-turn absolute encoder mounted on the rotor shaft. The LD 302 does not need an absolute encoder for operating PMmotors. It detects the rotor position by creating a test signal before the first motor start. However, it is possible to use a single-turn absolute encoder for rotor position detection. Switch to absolute encoder type after normal commissioning is finished.

9.4 Emergency Operation UPS

For emergency operation in case of mains power failure, it is possible to use a 230 V UPS. Operation with a UPS requires a UPS control card connected on the frequency converter. For each lift ride, the frequency converter determines and stores the direction of the load. If a mains power failure occurs during a lift ride and after applying the UPS voltage, the lift controller starts the lift with reduced speed (Evacuation Speed Veva) in the correct direction to the next floor level. For more detailed information, contact Danfoss.

VLT® Lift Drive LD 302

10.1 Special Conditions

10.1.1 Extreme Running Conditions

Short circuit (motor phase – phase)

The frequency converter is protected against short circuits. A short circuit between 2 output phases causes an overcurrent in the converter. If the short circuit current exceeds the permitted value, the frequency converter is turned off (Alarm 16 trip lock). See the relevant Design Guide for protection against a short circuit at the load sharing and brake outputs.

Switching on the output

Switching on the output between the motor and the frequency converter may cause an error, but does not damage the frequency converter.

Motor-generated overvoltage

The voltage in the intermediate circuit is increased when the motor acts as a generator. The increase in voltage occurs in following cases:

The load drives the motor (at constant output

•

frequency from the frequency converter), that is

1010

the load generates energy. During ramp-down with high moment of inertia,

•

low friction, and too short ramp-down time for the energy to be dissipated as a loss in the frequency converter, the motor, and the installation.

Incorrect slip compensation setting may cause

•

higher DC-link voltage. Back-EMF from PM motor operation. If coasted at

•

high RPM, the PM motor back-EMF may potentially exceed the maximum voltage tolerance of the frequency converter and cause damage.

10.1.2

The frequency converter supports thermal motor protection (motor overheating) by using a motor thermistor in motor windings (PTC sensor) or a mechanical thermal switch (Klixon type). The thermistor input, terminal 50 and 53, is used to connect the PTC or Klixon.

In operating mode, the lift operates as long as the thermistor input is below 3 kΩ. If the thermistor input is above 3 kΩ, an “Over Temperature”-warning is generated. When this warning is generated, the lift cannot be started, or it is put to a hold after completion of the ride. Further operation is only possible if the motor temperature is below the critical motor temperature.

Motor Thermal Protection

Illustration 10.1 Motor Thermistor

WARNING

The frequency converter must be equipped with a break chopper and a connected brake resistor.

Mains drop-out

During a mains drop-out, the frequency converter keeps running until the intermediate circuit voltage drops below the minimum stop level. The minimum stop level is typically 15% below the frequency converter's lowest rated supply voltage. The mains voltage before the drop-out and the motor load determines how long it takes for the inverter to coast.

Table 11.2 Number of Motor Poles

Table 11.2 shows the number of poles for normal speed ranges of various motor types. Define motors designed for other frequencies separately. The motor pole value is always an even number and refers to the total number of poles. The frequency converter bases the initial setting of

parameter 1-39 Motor Poles on parameter 1-23 Motor Frequency and parameter 1-25 Motor Nominal Speed.

1-40 Back EMF at 1000 RPM

Range: Function:

Size related*

[0 9000 V]

Set the nominal back EMF for the motor when running at 1,000 RPM. Back EMF is the voltage generated by a PM motor when no frequency converter is connected and the shaft is turned externally. Back EMF is normally specified for nominal motor speed or for 1,000 RPM measured between 2 lines. If the value is not available for a motor speed of 1,000 RPM, calculate the correct value as follows. If back EMF is for example. 320 V at 1,800 RPM, it can be calculated at 1,000 RPM as follows:

Example

Back EMF 320 V at 1,800 RPM. Back EMF= (Voltage/RPM)*1,000 = (320/1800)*1,000 =

178.

This parameter is only active when

Range: Function:

NOTICE

Severe filtering can cause bad dynamic performance.

Set a time constant for the speed control lowpass filter. The low-pass filter improves steadystate performance and dampens oscillations on the feedback signal. This is an advantage if there is a great amount on noise in the system, see Illustration 11.3. For example, if a time constant (τ) of 100 ms is programmed, the cut-off frequency for the low-pass filter is 1/0.1= 10 RAD/s. This value corresponds to (10/2 x π) = 1.6 Hz. The PID regulator only regulates a feedback signal that varies by a frequency of less than 1.6 Hz. If the feedback signal varies by a higher frequency than

1.6 Hz, the PID regulator does not react.

1) High overload = 160% torque during 60 s, Normal overload = 110% torque during 60 s

2) American Wire Gauge.

3) Measured using 5 m [16.4 ft] screened motor cables at rated load and rated frequency.

4) The typical power loss is at nominal load conditions and expected to be within cable conditions). Values are based on a typical motor efficiency (eff2/eff3 border line). Motors with lower efficiency also add to the power loss in the frequency converter and opposite. If the switching frequency is increased compared to the default setting, the power losses may rise significantly. LCP and typical control card power consumptions are included. Further options and customer load may add up to 30 W to the losses. (Though typical only 4 W extra for a fully loaded control card, or options for slot A or slot B, each).
