Introduction Programming Guide

RCD

Residual current device.

Set-up

Save parameter settings in 4 set-ups. Change among the 4 parameter set-ups and edit 1 set-up while this set-up is inactive.

SFAVM

Acronym describing the switching pattern stator uxoriented asynchronous vector modulation.

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.

Smart logic control (SLC)

The SLC is a sequence of user-dened actions executed when the associated user-dened events are evaluated as true by the smart logic controller (parameter group 13-** Smart Logic Control).

STW

Status word.

THD

Total harmonic distortion states the total contribution of harmonic distortion.

Thermistor

A temperature-dependent resistor placed where the temperature is monitored (frequency converter or motor).

Trip

A state entered in fault situations, for example if the frequency converter is subject to overvoltage or when it is protecting the motor, process, or mechanism. Restart is prevented until the cause of the fault has disappeared, and the trip state is canceled by activating reset or, sometimes, by being programmed to reset automatically. Do not use trip for personal safety.

Trip lock

A state entered in fault situations when the frequency converter is protecting itself and requiring physical intervention, for example if the frequency converter is subject to a short circuit on the output. A locked trip can only be canceled by cutting o 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, in some cases, by being programmed to reset automatically. Do not use trip lock 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 stability, both when the speed reference is changed and in relation to the load torque.

Introduction Programming Guide

In rare cases, long control cables and analog signals result in 50/60 Hz ground loops due to noise from mains supply cables. If this occurs, break the shield or insert a 100 nF capacitor between shield and chassis.

Connect the digital and analog inputs and outputs separately to the common inputs (terminal 55) of the frequency converter to avoid that ground currents from both groups aect other groups. For example, switching on the digital input could disturb the analog input signal.

PM Motor Set-up in VVC

Initial programming steps

1. Set parameter 1-10 Motor Construction to the following options to activate PM motor operation:

1a [1] PM, non salient SPM

1b [3] PM, salient IPM

2. Select [0] Open Loop in parameter 1-00 Congu- ration Mode.

NOTICE

Encoder feedback is not supported for PM motors.

Programming motor data

After selecting 1 of the PM motor options in parameter 1-10 Motor Construction, 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. Find the information on the motor nameplate and in the motor datasheet.

Program the following parameters in the listed order:

1. Parameter 1-24 Motor Current.

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

3. Parameter 1-25 Motor Nominal Speed.

4. Parameter 1-39 Motor Poles.

5. Parameter 1-30 Stator Resistance (Rs). Enter line-to-common stator winding resistance (Rs). If only line-line data is available, divide the line-line value by 2 to achieve the line-tocommon (starpoint) value. It is also possible to measure the value with an ohmmeter, which also takes the resistance of the cable into account. Divide the measured value by 2 and enter the result.

6. Parameter 1-37 d-axis Inductance (Ld). Enter line-to-common direct axis inductance of the PM motor. If only line-to-line data is available, divide the line-line value by 2 to achieve the line-common (starpoint) value. It is also possible to measure the value with an inductance meter, which also takes the inductance of the cable into account. Divide the measured value by 2 and enter the result.

7. Parameter 1-40 Back EMF at 1000 RPM. Enter line-to-line back EMF of the PM motor at 1000 RPM mechanical speed (RMS value). 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 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: For example, if back EMF at 1800 RPM is 320 V, the back EMF at 1000 RPM is: Back EMF=(Voltage/ RPM)x1000=(320/1800)x1000=178. Program this value for parameter 1-40 Back EMF at 1000 RPM.

Test motor operation

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

Parking

This function is the recommended option for applications where the motor rotates at slow speed (for example windmilling in fan applications). Parameter 2-06 Parking Current and parameter 2-07 Parking Time are adjustable. Increase the factory setting of these parameters for applications with high inertia.

Start the motor at nominal speed. If the application does not run well, check the VVC+ PM settings. Table 3.13 shows recommendations in dierent applications.
