81USParameter DescriptionKI DecelCurrent Control GainUnit: -Value range: 1...500Factory setting: 30Unit: -Value range: 0.00...2.55Factory setting: 2.00This parameter is only visible in open loop mode (LF.4 = IOPEn). Thisparameter is used to prevent spotting and or overshoot during thedeceleration phase. It is especially useful when running high slipmotors.This parameter is only visible in open loop mode (LF.4 = IOPEn). Thisparameter adjusts the gain of the openloop current control. A gainwhich is too high will cause the motor to oscillate severely.Mag. Current ControlGain Unit: -Value range: 0.00...2.55Factory setting: 2.00This parameter is only visible in open loop mode (LF.4 = IOPEn). Thisparameter adjusts the gain of the openloop magnetizing currentcontrol. A gain which is too high will cause the motor to oscillateseverely.Encoder ResolutionMultiplierThis parameter can be used to increase the resolution of encoderswith analog sine/cosine tracks. The encoder types are SIN/COS,Hiperface, EnDat.Unit: 1Value range: 0...13Factory setting: 2The value corresponds to the multiplier using the following relation.Actual Encoder Resolution = Encoder base ppr x 2 (LF76)Example: Sin/Cos encoder with base resolution of 2048 pprWith LF.76 = 8 the actual measured resolution is:2048 x 2 8 = 524288 counts / revHigher values give better resolution especially for gearless applica-tions. However higher values make the system more susceptible todisturbances due to noise. Therefore the actual value which can beused will ultimately be limited by the noise being picked up on theencoder cable.
