151ADVANCED PARAMETER-SETTING MODECommissioning manual Powerdrive MD2/FX4617 en - 2017.09 / e5.19.2 - Explanation of parameters in menu 18• Menu reserved for POWERDRIVE MD2R drives.NB:On products such as MD2R, the term «active rectifier» appliesto the converter connected to the mains, the term «inverter»applies to the converter connected to the motor or generator.Initialisation procedure for the serial link between theactive rectifier and the inverter in MD2R drives:1- Drive powered down, connect the keypad or parameter-setting interface to the active rectifier, power up thePOWERDRIVE.- Set 11.66 = Regen rectifier (2).- Check that 11.31 = Active rectifier on Main power (4) and10.75 = Yes (1).2- Power down the drive, connect the HMI to the inverter,power it up again:- Then set 11.66 = Regen inverter (1).- Set 11.31 in the desired operating mode (Induction motor inopen loop mode (1), Induction motor in vector control mode (2),or PM motor (Servo) in vector control mode (3)).- Leave 10.75 = Yes (1).3- Power down the drive, then power it up again.- Enter the menu 18 settings in accordance with the applicationrequirements.For any further information, please get in touch with your usualLEROY-SOMER contact.18.01 : Reactive powerAdjustment range: ± 3200.00 kVAFormat: 32 bitsIf the parameter is positive, the current is lagging the voltage.If the parameter is negative, the current is leading the voltage.18.02 : Active powerAdjustment range: ± 3200.00 kWFormat: 32 bits18.02 is the absorbed active power measured by the drive.If this parameter has been assigned to an analog output viamenu 7, 10 V corresponds to the maximum power measurableby the drive (I max = 150% of drive rated current).18.03 : DC bus voltageAdjustment range: 0 to 1300 VFormat: 16 bitsIndicates the DC bus voltage measurement in Regen modeonly.18.04 : Regen restart modeAdjustment range : Synchro x3 (0), Synchro x1 (1),Without synchro (2)Factory setting : Synchro x1 (1)Format: 8 bitsDefines the start mode when enabled.Synchro x3 (0):Three attempts to resynchronise. Then, in the event of failure,the «Mains synchro» trip is generated.Synchro x1 (1):Only one attempt to synchronise. In the event of failure, the«Mains synchro» trip is generated immediately.Without Synchro (2):Reserved.18.05 : DC bus voltage set pointAdjustment range : 0 to 1300 VFactory setting : T rating = 660 V, TH rating = 1070 VFormat: 16 bitsThe sinusoidal rectifier sets the DC bus to the level specifiedby this parameter. The bus voltage must always be greaterthan the supply voltage between phases x √2.Recommended values:Mains supply 400 V: 660 VMains supply 460 V: 740 VMains supply 480 V: 760 VMains supply 690 V: 1070 V18.06 : Voltage loop proportional gainAdjustment range: 0 to 32000Factory setting: 1000Format: 16 bits18.07 : Voltage loop integral gainAdjustment range: 0 to 32000Factory setting: 20Format: 16 bits18.08 : Mains voltageAdjustment range: 0 to 999 VFormat: 16 bitsThis is the rms voltage at the Regen drive input.18.09 : Mains frequencyAdjustment range: ± 400.0 HzFormat: 16 bitsIndicates the mains frequency.18.10 : Power feed forward compensationAdjustment range: 0.00 to 100.00%Factory setting: 0.00%Format: 16 bitsThis parameter can be used to reduce the transient voltages ofthe DC bus in the event of load power impacts.
