The guided commissioning has selected the parameters of the current controller insuch a way that they can be used without having to be changed in most applications.If, in exceptional cases, an optimization of the behavior of the current controllers is tobe done, the reference value step-change during the flux-formation phase can beused for this. If parameterized appropriately, the reference value of the flux-formingcurrent components jumps to the value Current During Flux-Formation 781 andthen changes in a controlled way to the magnetizing current after the expiry of theMaximum Flux-Formation Time 780. The operating point necessary for the adjustmentdemands the setting of parameter Minimum Frequency 418 to 0.00 Hz, as thedrive is accelerated after magnetizing. The measurement of the jump reply, which isdefined by the ratio of the currents mentioned, should be done in the motor supplyline by means of a measuring current transformer of a sufficient bandwidth.Note:The internally calculated actual value for the flux-forming current componentcannot be output via the analog output for this measurement as thetime resolution of the measurement is not sufficient.To set the parameters of the PI controller, the Amplification 700 is increased firstuntil the actual value overshoots distinctly during the control process. Now, the amplificationis reduced to about a half again and then the Integral Time 701 is synchronizeduntil actual value overshoots slightly during the control process.The settings of the current controllers should not be too dynamic in order to ensure asufficient reserve range. The control tends to increased oscillations if the reserverange is reduced.The dimensioning of the current controller parameters by calculation of the time constantis to be done for a switching frequency of 2 kHz. For other switching frequencies,the values are adapted internally so that the setting can remain unchanged forall switching frequencies. The dynamic properties of the current controller improve ifthe switching and scanning frequency increases.The fixed time interval for the modulation results in the following scanning frequenciesof the current controller via parameter Switching Frequency 400.1)SettingsSwitching frequency Scanning Frequency2 kHz 1) 2 kHz4 kHz 4 kHz8 kHz 8 kHz12 kHz 8 kHz16 kHz 8 kHzThis switching frequency can only be set for the parameter Min. Switching Frequency401.16.5.2 Torque ControllerThe torque-controlled configurations 230 and 430 often demand limitation of thespeed in the operating points without load moment. The controller increases thespeed in order to reach the reference torque until the Frequency Upper Limit 767 orthe Frequency Lower Limit 768 is reached. As from the limit value the drive is controlledto maximum speed, which corresponds to the behavior of the speed controller.Thus, the controller is limited to the Maximum Frequency 419.ParameterSettingsNo. Description Min.

16.5.2.1 Limit Value SourcesThe limitation of the frequency can be done by setting fixed values and also by linkingto an analog input parameter. The analog value is limited via parameters MinimumReference Percentage 518 and Maximum Reference Percentage 519, but does notconsider the Gradient Percentage Ramp 477 of the reference percentage valuechannel.The assignment is done for the torque controller via parameters Frequency UpperLimit Source 769 and Frequency Lower Limit Source 770.Operation modeFunction101 - Analog Input MFI1AThe source is the multifunctional input 1 in ananalog Operation Mode 452.110 - Fixed LimitThe selected parameter values are taken intoaccount to limit the speed controller.201 - Inv.

Via parameter Operation Mode 720, you can select theoperation mode for the speed controller. The operation mode defines the use of theparameterizable limits. These are referred to the direction of rotation and the directionof the torque and depend on the selected configuration.Operation mode0 - Speed Controller Off1 -2 -Limits forMotor / GeneratorLimits forpos. / neg. TorqueFunctionThe controller is deactivated or the torque-formingcomponent is zero.The limitation of the speed controller assigns the upperlimit to the motor operation of the drive. Independentof the direction of rotation, the same limit isused. The same applies in the case of regenerativeoperation with the lower limit.The assignment of the limit is done by the sign of thevalue to be limited. Independent of the motor or generatoroperating points of the drive, the positive limitationis done by the upper limit. The lower limit isregarded as a negative limitation.Operation mode 2anticlockwiseclockwiseanticlockwiseclockwisegeneratormotorgeneratormotormotorgeneratornmotorgeneratornCurrent limit 728Current limit generator op. 72902/06 155
