7. Use the navigation keys to scroll to0-01 Language.8. Select language and press [OK].9. If a jumper wire is in place between controlterminals 12 and 27, leave 5-12 Terminal 27 DigitalInput at factory default. Otherwise, No Operationshould be selected in 5-12 Terminal 27 DigitalInput. For frequency converters with an optionalbypass, no jumper wire is required betweencontrol terminals 12 and 27.10. 3-02 Minimum Reference11. 3-03 Maximum Reference12. 3-41 Ramp 1 Ramp Up Time13. 3-42 Ramp 1 Ramp Down Time14. 3-13 Reference Site.

Activate PM motor operation 1-10 MotorConstruction, select (1) PM, non salient SPM2. Set 0-02 Motor Speed Unit to [0] RPMProgramming motor dataAfter selecting PM motor in 1-10 Motor Construction, thePM motor-related parameters in parameter groups 1-2*Motor Data, 1-3* Adv. Motor Data and 1-4* are active.The necessary data can be found on the motor nameplateand in the motor data sheet.Program the following parameters in the listed order1. 1-24 Motor Current2. 1-26 Motor Cont. Rated Torque3. 1-25 Motor Nominal Speed4. 1-39 Motor Poles5. 1-30 Stator Resistance (Rs)Enter line to common stator winding resistance(Rs). If only line-line data are available, divide theline-line value with 2 to achieve the line tocommon (starpoint) value.It is also possible to measure the value with anohmmeter, which will also take the resistance ofthe cable into account. Divide the measuredvalue by 2 and enter the result.6. 1-37 d-axis Inductance (Ld)Enter line to common direct axis inductance ofthe PM motor.If only line-line data are available, divide the line-line value with 2 to achieve the line-common(starpoint) value.It is also possible to measure the value with aninductancemeter, which will also take theinductance of the cable into account. Divide themeasured value by 2 and enter the result.7. 1-40 Back EMF at 1000 RPMEnter line to line back EMF of PM Motor at 1000RPM mechanical speed (RMS value). Back EMF isthe voltage generated by a PM motor when nodrive is connected and the shaft is turnedexternally. Back EMF is normally specified fornominal motor speed or for 1000 RPM measuredbetween two lines. If the value is not available fora motor speed of 1000 RPM, calculate the correctvalue as follows: If back EMF is e.g. 320 V at 1800RPM, it can be calculated at 1000 RPM as follows:Back EMF = (Voltage / RPM)*1000 =(320/1800)*1000 = 178. This is the value thatmust be programmed for 1-40 Back EMF at 1000RPM.Test Motor Operation1. Start the motor at low speed (100 to 200 RPM). Ifthe motor does not turn, check installation,general programming and motor data.2. Check if start function in 1-70 PM Start Mode fitsthe application requirements.Rotor detectionThis function is the recommended choice for applicationswhere the motor starts from standstill, e.g. pumps orconveyors. On some motors, an acoustic sound is heardwhen the impulse is sent out. This does not harm themotor.ParkingThis function is the recommended choice for applicationswhere the motor is rotating at slow speed eg. windmillingin fan applications. 2-06 Parking Current and 2-07 ParkingTime can be adjusted. Increase the factory setting of theseparameters for applications with high inertia.Commissioning VLT® HVAC Drive Operating InstructionsMG11AJ02 - Rev. 2013-07-31 255 5
