Introduction

Illustration 1: Wiring Schematic

A=Analog, D=Digital

1) Do not connect cable shield. Terminal 37 is used for Safe Torque Off (STO). For STO installation instructions, refer to the VLT® Frequency Converters - Safe Torque

Off Operating Guide. Long control cables and analog signals may in rare cases, 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 affect other groups, connect the digital and analog inputs and outputs separately to the common inputs (terminals 20, 55, and 39) of the drive. For example, switching on the digital input may disturb the analog input signal.

Parameter Descriptions

4.1.2 0-1* Set-up Operations

Define and control the individual parameter setups. The drive has 4 parameter setups that can be programmed independently of each other. This makes the drive very flexible and able to solve advanced control functionality problems, often saving the cost of external control equipment. Parameter setups can be used to program the drive to operate according to 1 control scheme in 1 setup (for example, motor 1 for horizontal movement) and another control scheme in another setup (for example, motor 2 for vertical movement). Alternatively, parameter setups can be used by an OEM machine builder to identically program all their factoryfitted drives for different machine types within a range to have the same parameters. During production/commissioning, simply select a specific setup depending on which machine the drive is installed on.

The active setup (that is the setup in which the drive is currently operating) can be selected in parameter 0-10 Active Set-up and is shown in the LCP. By using multi setup, it is possible to switch between setups with the drive running, or it can be stopped via digital input or serial communication commands. If it is necessary to change setups while the drive is running, ensure that parame- ter 0-12 This Set-up Linked to is programmed as required. By using parameter 0-11 Edit Set-up, it is possible to edit parameters within any of the setups while continuing the operation of the drive in its active setup, which can be a different setup to the one being edited. By using parameter 0-51 Set-up Copy, it is possible to copy parameter settings between the set-ups to enable quicker commissioning if similar parameter settings are required in different setups.

Use parameter 0-51 Set-up Copy to copy a setup to 1 or all other setups. Stop the drive before switching between setups where parameters marked not changeable during operation have different values. To avoid conflicting settings of the same parameter within 2 different setups, link the setups together using parameter 0-12 This Set-up Linked to. Parameters which are not changeable during operation are marked FALSE in the Change during operation field.

4.2.2.2 PM Motor Set-up

This section describes how to set up a PM motor.

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:

Parameter 1-24 Motor Current.

Parameter 1-25 Motor Nominal Speed.

Parameter 1-26 Motor Cont. Rated Torque.

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, configure the following parameters manually:

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

ble, divide the line-line value by 2 to get the line-common value.

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 line-line value by 2 to get the line-common value.

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 drive is connected and the shaft is turned externally. It is normally specified

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

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

motor data.

Check if the start function in parameter 1-70 Start Mode fits the application requirements.

4.2.2.2.1 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 drive performs the rotor detection. This does not harm the motor.

4.2.2.2.2 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.

4.2.2.2.3 Application-specific 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.

Parameter Descriptions

N O T I C E

If parameter 40-50 Flux Sensorless Model Shift is set to [0] Off, this parameter is ignored.

Enter the minimum motor current at low speed, see parameter 1-53 Model Shift Frequency. Increasing this current improves motor torque at low speed. Parameter 1-66 Min. Current at Low Speed is enabled when parameter 1-00 Configuration Mode is set to [0] Speed open loop only. The drive runs with constant current through motor for speeds below 10 Hz. For speeds above 10 Hz, the motor flux model in the drive controls the motor. Parameter 4-16 Torque Limit Motor Mode and/or parameter 4-17 Torque Limit Generator Mode automatically adjust parameter 1-66 Min. Current at Low Speed. The parameter with the highest value adjusts parameter 1-66 Min. Current at Low Speed. The current setting in parameter 1-66 Min. Current at Low Speed is composed of the torque generating current and the magnetizing current. Example: Set parameter 4-16 Torque Limit Motor Mode to 100% and set parameter 4-17 Torque Limit Generator Mode to 60%. Parameter 1-66 Min. Current at Low Speed automatically adjusts to about 127%, depending on the motor size.

N O T I C E

This function is not recommended for hoisting applications. For power levels above 55 kW, flux mode must be used to achieve the best performance.

N O T I C E

To obtain the best flying start performance, the advanced motor data, parameter 1-30 Stator Resistance (Rs) to parameter 1-35 Main Reactance (Xh), must be correct.

This function makes it possible to catch a freely spinning motor, for example coasted because of mains dropout. When flying start is enabled, parameter 1-71 Start Delay and parameter 1-72 Start Function have no function. When options [1] Enable and [2] Enabled always are enabled, parameter 1-58 Flying Start Test Pulses Current and parameter 1-59 Flying Start Test Pulses Frequency are used to specify conditions for flying start. For flying start version 1, options [3] Enabled ref. dir. and [4] Enab. always ref. dir. are set to search for the motor in the reference direction only, which allows a faster execution of the motor catch. For flying start version 2, options [11] to [14] are specific to asynchronous motor (induction motor) in VVC+ up to 132 Hz output frequency. These options provide a faster, more reliable, and robust flying start. When parameter 1-73 Flying Start is enabled, parameter 1-71 Start Delay has no function. Search direction for flying start is linked to the setting in parameter 4-10 Motor Speed Direction. [0] Clockwise: Flying start searches in clockwise direction. If not successful, a DC brake is carried out. [2] Both Directions: The flying start first searches in the direction determined by the last reference (direction). If not finding the speed, it searches in the other direction. If not successful, a DC brake activates in the time set in parameter 2-02 DC Braking Time. Start then takes place from 0 Hz.

Premagnetizing

Builds up a magnetic field while the motor is stopped. This allows the motor to produce torque quickly at subsequent start commands (asynchronous motors only). This premagnetizing function does not help the 1st start command. Two different solutions are available to premagnetize the machine for the 1st start command:

Start the drive with a 0 RPM reference and wait 2–4 rotor time constants before increasing the speed reference.

Use the start delay with DC hold:

Set parameter 1-71 Start Delay to the required premagnetizing time (2–4 rotor time constants). See the time constants description further in this section. Set parameter 1-72 Start Function to either [0] DC hold or [1] DC Brake. Set the DC hold or DC brake current magnitude (parameter 2-00 DC Hold Current or pa- rameter 2-01 DC Brake Current) to be equal to I_pre-mag = Unom/(1.73 x Xh).

Sample rotor time constants = (Xh+X2)/(6.3*Freq_nom*Rr)

Precise ramp stop

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.

[1]

Cnt stop with reset

Counts the number of pulses, typically from an encoder, and generates a stop signal after a preprogrammed number of pulses, defined 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 are reset.

[2]

Cnt stop w/o reset

Same as [2] Cnt stop with reset but the number of pulses counted during ramp down to 0 RPM are 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.

Programming Guide

The precise stop functions are advantageous in applications where high precision is required. If using a standard stop command, the accuracy is 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 drive 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 drive 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 find this delay as it is a sum of sensor, PLC, drive, and mechanical parts.

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

4.2.10.2 KTY Sensor Connection

KTY sensors are used especially in permanent magnet servo motors (PM motors) for dynamic adjusting of motor parameters as stator resistance (parameter 1-30 Stator Resistance (Rs)) for PM motors and also rotor resistance (parameter 1-31 Rotor Resistance (Rr)) for asynchronous motors, depending on winding temperature. The calculation is:

Rs = Rs KTY sensors can be used for motor protecting (parameter 1-97 KTY Threshold level). can handle 3 types of KTY sensors, defined in

parameter 1-95 KTY Sensor Type. The actual sensor temperature can be read out from parameter 16-19 KTY sensor temperature.

No brake resistor installed.

[1]

Resistor brake

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

[2]

AC brake

Improves braking without using a brake resistor. 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.

N O T I C E

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

Parameter 2-11 Brake Resistor (ohm)

Table 154: Parameter 2-11 Brake Resistor (ohm)

Parameter Descriptions

Set the brake resistor value in Ω. This value is used for monitoring the power to the brake resistor in parameter 2-13 Brake Power Monitoring. This parameter is only active in drives with an integral dynamic brake. Use this parameter for values without decimals.

For a selection with 2 decimals, use parameter 30-81 Brake Resistor (ohm).

Parameter 2-12 Brake Power Limit (kW)

Table 155: Parameter 2-12 Brake Power Limit (kW)

Parameter 2-12 Brake Power Limit (kW) is the expected average power dissipated in the brake resistor over a period of 120 s. It is used as the monitoring limit for parameter 16-33 Brake Energy Average and thereby specifies when a warning/alarm is to be given. To calculate parameter 2-12 Brake Power Limit (kW), the following formula can be used.

br, avg W =

is the average power dissipated in the brake resistor, Rbr is the resistance of the brake resistor. tbr is the active braking time

br,avg

within the 120 s period, Tbr. Ubr is the DC voltage where the brake resistor is active. This depends on the unit as follows:

•

T2 units: 390 V

•

T5 units: 810 V

•

T6 units: 943 V/1099 V for D enclosures

•

T7 units: 1099 V

If Rbr is not known, or if Tbr is different from 120 s, the practical approach is to run the brake application, read parameter 16-33 Brake Energy Average and then enter this + 20% in parameter 2-12 Brake Power Limit (kW).

Parameter 2-13 Brake Power Monitoring

Table 156: Parameter 2-13 Brake Power Monitoring

This parameter is only active in drives with a brake. This parameter enables monitoring of the power to the brake resistor. The power is calculated based on the resistance (parameter 2-11 Brake Resistor (ohm)), the DC-link voltage, and the resistor duty time. If power monitoring is set to [0] Off 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%).
