Introduction

VLT® AutomationDrive FC 301/302

Intermittent duty cycle

An intermittent duty rating refers to a sequence of duty cycles. Each cycle consists of an on-load and an o-load period. The operation can be either periodic duty or nonperiodic duty.

LCP

The local control panel makes up a complete interface for control and programming of the frequency converter. The control panel is detachable and can be installed up to 3 m (10 ft) from the frequency converter, that is, in a front panel with the installation kit option.

NLCP

Numerical local control panel interface for control and programming of the frequency converter. The display is numerical and the panel is used to show process values. The NLCP has no storage and copy functions.

lsb

Least signicant bit.

msb

Most signicant bit.

MCM

Short for mille circular mil, an American measuring unit for cable cross-section. 1 MCM=0.5067 mm2.

Online/oine parameters

Changes to online parameters are activated immediately after the data value is changed. Press [OK] to activate changes to o-line parameters.

Process PID

The PID control maintains the required speed, pressure, temperature, and so on, by adjusting the output frequency to match the varying load.

PCD

Process control data.

Power cycle

Switch o the mains until display (LCP) is dark, then turn power on again.

Pulse input/incremental encoder

An external, digital pulse transmitter used for feeding back information on motor speed. The encoder is used in applications where great accuracy in speed control is required.

RCD

Residual current device.

Set-up

Save parameter settings in 4 set-ups. Change between the 4 parameter set-ups and edit 1 set-up, while another setup is active.

SFAVM

Switching pattern called stator ux-oriented asynchronous vector modulation (parameter 14-00 Switching Pattern).

Slip compensation

The frequency converter compensates for the motor slip by giving the frequency a supplement that follows the measured motor load keeping the motor speed almost constant.

SLC

The SLC (smart logic control) is a sequence of user-dened actions executed when the associated user-dened events are evaluated as true by the SLC. (See chapter 3.13 Parameters: 13-** Smart Logic Control).

STW

Status word.

FC standard bus

Includes RS485 bus with FC protocol or MC protocol. See parameter 8-30 Protocol.

THD

Total harmonic distortion states the total contribution of harmonic.

Thermistor

A temperature-dependent resistor placed on the frequency converter or the motor.

Trip

A state entered in fault situations, for example if the frequency converter is subject to an overtemperature or when the frequency converter is protecting the motor, process, or mechanism. The frequency converter prevents a restart until the cause of the fault has disappeared. To cancel the trip state, restart the frequency converter. Do not use the trip state for personal safety.

Trip lock

The frequency converter enters this state in fault situations to protect itself. The frequency converter requires physical intervention, for example when there is a short circuit on the output. A trip lock can only be canceled by disconnecting mains, removing the cause of the fault, and reconnecting the frequency converter. Restart is prevented until the trip state is canceled by activating reset or, sometimes, by being programmed to reset automatically. Do not use the trip lock state for personal safety.

VT characteristics

Variable torque characteristics used for pumps and fans.

VVC

If compared with standard voltage/frequency ratio control, voltage vector control (VVC+) improves the dynamics and the stability, both when the speed reference is changed and in relation to the load torque.

WARNING

UNINTENDED START

When the frequency converter is connected to AC mains, DC supply, or load sharing, the motor may start at any time. Unintended start during programming, service, or repair work can result in death, serious injury, or property damage. The motor can start via an external switch, a eldbus command, an input reference signal from the LCP, or after a cleared fault condition.

To prevent unintended motor start:

Disconnect the frequency converter from the

•

mains.

Press [O/Reset] on the LCP before

•

programming parameters.

Completely wire and assemble the frequency

•

converter, motor, and any driven equipment before connecting the frequency converter to AC mains, DC supply, or load sharing.

WARNING

DISCHARGE TIME

The frequency converter contains DC-link capacitors, which can remain charged even when the frequency converter is not powered. High voltage can be present even when the warning LED indicator lights are o. Failure to wait the specied time after power has been removed before performing service or repair work can result in death or serious injury.

NOTICE!

When using the Safe Torque O, always follow the

instructions in VLT® Frequency Converters - Safe Torque

O Operating Instructions.

NOTICE!

Control signals from, or internally within, the frequency converter may in rare cases be activated in error, be delayed, or fail to occur entirely. When used in situations where safety is critical, for example when controlling the electromagnetic brake function of a hoist application, do not rely on these control signals exclusively.

NOTICE!

Hazardous situations must be identied by the machine builder/integrator who is responsible for considering the necessary preventive means. More monitoring and protective devices may be included, always according to valid national safety regulations, for example law on mechanical tools and regulations for the prevention of accidents.

Crane, lifts, and hoists

The controlling of external brakes must always have a redundant system. The frequency converter can in no circumstances be the primary safety circuit. Comply with relevant standards, for example: Hoists and cranes: IEC 60204-32 Lifts: EN 81

Protection mode

Once a hardware limit on motor current or DC-link voltage is exceeded, the frequency converter enters the protection mode. Protection mode means a change of the PWM modulation strategy and a low switching frequency to minimize losses. This continues for 10 s after the last fault and increases the reliability and the robustness of the frequency converter while re-establishing full control of the motor.

Introduction Programming Guide

1 1

In hoist applications, protection mode is not usable because the frequency converter is unable to leave this mode again and therefore it extends the time before activating the brake, which is not recommended. Protection mode can be disabled by setting parameter 14-26 Trip Delay at Inverter Fault to 0, which means that the frequency converter trips immediately if 1 of the hardware limits is exceeded.

1.5 Electrical Wiring

NOTICE!

Disabling protection mode in hoisting applications (parameter 14-26 Trip Delay at Inverter Fault = 0) is recommended.

Introduction

VLT® AutomationDrive FC 301/302

1) Terminal 37 is not included in FC 301 (except enclosure type A1). Relay 2 and terminal 29 have no function in FC 301.

2) Do not connect cable shield.

Very long control cables and analog signals may in rare cases, and depending on installation, result in 50/60 Hz ground loops due to noise from mains supply cables.

If 50/60 Hz ground loops occur, consider breaking the shield or insert a 100 nF capacitor between shield and enclosure.

To avoid ground currents from both groups to

aect other groups, connect the digital and analog inputs and outputs separately to the common inputs (terminals 20, 55, and 39) of the frequency converter. For example, switching on the digital input may disturb the analog input signal.

Input polarity of control terminals

NOTICE!

Control cables must be shielded/armored.

See the section Grounding of Shielded Control Cables in the design guide for the correct termination of control cables.

•

Pump/fan.

•

The following 4 eldbusses can be selected:

PROFIBUS.

•

PROFINET.

•

DeviceNet.

•

EtherNet/IP.

•

NOTICE!

The frequency converter ignores the start conditions when SAS is active.

Each parameter has a name and number which remain the same regardless of the programming mode. In the main menu mode, the parameters are divided into groups. The rst digit of the parameter number (from the left) indicates the parameter group number.

All parameters can be changed in the Main Menu. However, depending on the choice of conguration (parameter 1-00 Conguration Mode), some parameters can be hidden. For example, open loop hides all the PID parameters, and other enabled options make more parameter groups visible.

2.1.9 Parameter Selection

In the main menu mode, the parameters are divided into groups. Select a parameter group with the navigation keys.

After selecting a parameter group, select a parameter with the navigation keys. The middle section on the display shows the parameter number and name, and the selected parameter value.

NOTICE!

The smart set-up runs automatically on the rst powerup of the frequency converter or after a reset to factory settings. If no action is taken, the SAS screen automatically disappears after 10 minutes.

Dene and control the individual parameter set-ups. The frequency converter has 4 parameter set-ups that can be programmed independently of each other. This makes the frequency converter very exible and able to solve advanced control functionality problems, often saving the cost of external control equipment. Parameter set-ups can be used to program the frequency converter to operate according to 1 control scheme in 1 set-up (for example motor 1 for horizontal movement) and another control scheme in another set-up (for example motor 2 for vertical

Alternatively, parameter set-ups can be used by an OEM machine builder to identically program all their factory-tted frequency converters for dierent machine types within a range to have the same parameters. During production/commissioning, simply select a specic set-up depending on which machine the frequency converter is installed on. The active set-up (that is the set-up in which the frequency converter is currently operating) can be selected in parameter 0-10 Active Set-up and is shown in the LCP. By using multi set-up, it is possible to switch between set-ups with the frequency converter running, or it can be stopped via digital input or serial communication commands.

Initial programming steps

To activate PM motor operation, select [1] PM, non-salient SPM in parameter 1-10 Motor Construction.

Programming motor data

After selecting a PM motor, the PM motor-related parameters in parameter groups 1-2* Motor Data, 1-3* Adv. Motor Data, and 1-4* Adv. Motor Data II are active. The necessary data is on the motor nameplate and on the motor datasheet.

Program the following parameters in the order listed:

1. Parameter 1-24 Motor Current.

2. Parameter 1-25 Motor Nominal Speed.

3. Parameter 1-26 Motor Cont. Rated Torque.

4. Parameter 1-39 Motor Poles.

Run a complete AMA using parameter 1-29 Automatic Motor Adaptation (AMA) [1] Enable Complete AMA.

If a complete AMA is not performed, congure the following parameters manually:

1. Parameter 1-30 Stator Resistance (Rs) Enter the line-to-common stator winding resistance (Rs). If only line-line data is available,

Parameter Descriptions Programming Guide

divide the line-line value by 2 to get the linecommon value.

2. Parameter 1-37 d-axis Inductance (Ld) Enter the line-to-common direct axis inductance of the PM motor. If only line-line data is available, divide the lineline value by 2 to get the line-common value.

3. Parameter 1-40 Back EMF at 1000 RPM. Enter the line-to-line back EMF of the PM Motor at 1000 RPM (RMS value). Back EMF is the voltage generated by a PM motor when no frequency converter is connected and the shaft is turned externally. It is normally specied for nominal motor speed or for 1000 RPM measured between 2 lines. If the value is not available for a motor speed of 1000 RPM, calculate the correct value as follows: If back EMF is, for example, 320 V at 1800 RPM, it can be calculated at 1000 RPM as follows: Back EMF = (Voltage/RPM)x1000 = (320/1800)x1000 = 178.

Test motor operation

1. Start the motor at low speed (100–200 RPM). If the motor does not turn, check the installation, general programming, and motor data.

2. Check if the start function in parameter 1-70 Start Mode ts the application requirements.

Rotor detection

This function is the recommended selection for applications where the motor starts from standstill, for example pumps or conveyors. On some motors, a sound is heard when the frequency converter performs the rotor detection. This does not harm the motor.

Parking

This function is the recommended selection for applications where the motor is rotating at slow speed, for example windmilling in fan applications.

Parameter 2-06 Parking Current and parameter 2-07 Parking Time can be adjusted. Increase the factory setting of these

parameters for applications with high inertia.

Application-specic adjustment when running VVC

VVC+ is the most robust control mode. In most situations, it provides optimum performance without further adjustments. Run a complete AMA for best performance.

Start the motor at nominal speed. If the application does not run well, check the VVC+ PM settings. Table 3.4 contains recommendations for various applications.

Adaptation (AMA). Parameter groups 1-3* Adv. Motor Data and 1-4* Adv. Motor Data II cannot be adjusted while the motor is running.

NOTICE!

A simple check of the X1 + Xh sum value is to divide the line-to-line motor voltage by the sqrt(3) and divide this value by the motor no load current. [VL-L/sqrt(3)]/INL = X1 + Xh, see Figure 3.6. These values are important to magnetize the motor properly. For high-pole motors, it is highly recommended to perform this check.

NOTICE!

It is important to set motor parameter group 1-2* Motor Data correctly, since these form part of the AMA

algorithm. Perform an AMA to achieve optimum dynamic motor performance. It may take up to 10 minutes, depending on the power rating of the motor.

NOTICE!

Avoid generating external torque during AMA.

NOTICE!

If 1 of the settings in parameter group 1-2* Motor Data is changed, parameter 1-30 Stator Resistance (Rs) to parameter 1-39 Motor Poles, the advanced motor parameters, return to default setting.

NOTICE!

AMA works problem-free on 1 motor size down, typically works on 2 motor sizes down, rarely works on 3 sizes down, and never work on 4 sizes down. Keep in mind that the accuracy of the measured motor data is poorer when operating on motors smaller than the nominal frequency converter size.

Only optimal when the operational speed, for example the operational speed of a conveyor belt, is constant. This is an open-loop control. Achieves high repetitive precision at the stop point.

Counts the number of pulses, typically from an encoder, and generates a stop signal after a preprogrammed number of pulses, dened in parameter 1-84 Precise Stop Counter Value, has been received at terminal 29 or terminal 33. This is direct feedback with one-way closed-loop control. The counter function is activated (starts timing) at the edge of the start signal (when it changes from stop to start). After each precise stop, the number of pulses counted during ramp down to 0 RPM is reset.

Same as [2] Cnt stop with reset but the number of pulses counted during ramp down to 0 RPM is deducted from the counter value entered in parameter 1-84 Precise Stop Counter Value. This reset function can be used to compensate for the extra distance done during ramping down and to reduce the impacts of gradual wear of mechanical parts.

Stops at precisely the same point, regardless of the present speed. The stop signal is delayed internally when the present speed is lower than the maximum speed (set in parameter 4-19 Max Output Frequency). The delay is calculated on the basis of the reference speed of the frequency converter and not on the basis of the actual speed. Make sure that the frequency converter has ramped up before activating the speed compensated stop.

Same as Speed comp stop but after each precise stop, the number of pulses counted during ramp down to 0 RPM is reset.

Same as Speed comp stop but the number of pulses counted during ramp down to 0 RPM is deducted from the counter value entered in parameter 1-84 Precise Stop Counter Value. This reset function can be used to compensate for the extra distance done during ramping down

determined by the internal task time. That is not the case when using the precise stop function. It eliminates the task time dependence and increases the accuracy substantially. The frequency converter tolerance is normally given by its task time. However, by using its special precise stop function, the tolerance is independent of the task time because the stop signal immediately interrupts the execution of the frequency converter program. The precise stop function gives a highly reproducible delay from the stop signal is given until the ramping down starts. Run a test to

nd this delay as it is a sum of sensor, PLC,

frequency converter, and mechanical parts.

To ensure optimum accuracy, there should be at least 10 cycles during ramping down, see:

[2] AC brake Improves braking without using a brake resistor.

A brake resistor is incorporated in the system, for dissipation of surplus brake energy as heat. Connecting a brake resistor allows a higher DClink voltage during braking (generating operation). The resistor brake function is only active in frequency converters with an integral dynamic brake.

This parameter controls an overmagnetization of the motor when running with a generatoric load. This function can improve the OVC function. Increasing the electrical losses in the motor allows the OVC function to increase the braking torque without exceeding the overvoltage limit.

NOTICE!

The AC brake is not as ecient as dynamic braking with resistor. AC brake is for VVC+ mode in both open and closed loop.

Activates both of the above, including warning, trip, and alarm.

If power monitoring is set to [0] O or [1] Warning, the brake function remains active, even if the monitoring limit is exceeded. This may lead to thermal overload of the resistor. It is also possible to generate a warning via a relay/digital output. The measuring accuracy of the power monitoring depends on the accuracy of the resistance of the resistor (better than ±20%).

NOTICE!

Remove a warning arising with [0] O or [1] Warning by cycling the mains supply. The fault must be corrected rst. For [0] O or [1] Warning, the frequency converter keeps running even if a fault is located.

NOTICE!

The brake resistor disconnection function is tested during power-up. However, the brake IGBT test is performed when there is no braking. A warning or trip disconnects the brake function.

The testing sequence is as follows:

1. The DC-link ripple amplitude is measured for 300 ms without braking.

2. The DC-link ripple amplitude is measured for 300 ms with the brake turned on.

3. If the DC-link ripple amplitude while braking is lower than the DC-link ripple amplitude before braking + 1%: Brake

check has failed by returning a warning or

alarm.

4. If the DC-link ripple amplitude while braking is higher than the DC-link ripple amplitude before braking + 1%: Brake

3.3.3 2-2* Mechanical Brake

Parameters for controlling operation of an electro-magnetic (mechanical) brake, typically required in hoisting applications. To control a mechanical braking, a relay output (relay 01 or relay 02) or a programmed digital output (terminal 27 or

29) is required. Normally, this output must be closed

during periods when the frequency converter is unable to hold the motor, for example due to an excessive load. Select [32] Mechanical Brake Control for applications with an electro-magnetic brake in parameter 5-40 Function Relay,

parameter 5-30 Terminal 27 Digital Output, or parameter 5-31 Terminal 29 digital Output. When selecting [32] Mechanical brake control, the mechanical braking is

closed from start-up until the output current is above the level selected in parameter 2-20 Release Brake Current. During stop, the mechanical braking activates when the speed drops below the level specied in parameter 2-21 Activate Brake Speed [RPM]. If the frequency converter enters an alarm condition, an overcurrent, or overvoltage situation, the mechanical braking immediately cuts in. This is also the case during Safe Torque O.

NOTICE!

Protection mode and trip delay features (parameter 14-25 Trip Delay at Torque Limit and parameter 14-26 Trip Delay at Inverter Fault) may delay the activation of the mechanical braking in an alarm condition. These features must be disabled in hoisting applications.
