No.(Addr.Hex) Name LCD Display Description Values Pagen8-47(053A)Pull-In CurrentCompensation TimeConstant (for PMMotors)PM Pull-in I TcSets the time constant to make the pull-in current reference andactual current value agree. Decrease the value if the motorbegins to oscillate, and increase the value if it takes too longfor the current reference to equal the output current.Default: 5.0 sMin.: 0.0Max.: 100.0 –n8-48(053B) Pull-In Current (for PMMotors) PM No-load CurrDefines the d-Axis current reference during no-load operationat a constant speed. Set as a percentage of the motor ratedcurrent. Increase this setting if hunting occurs while running atconstant speed.Default: 30%Min.: 20Max.: 200 –n8-49(053C)d-Axis Current for HighEfficiency Control (forPM Motors) EnergySav ID LvlSets the d-Axis current reference when running a high load atconstant speed. Set as a percentage of the motor rated current. Default: <3>Min.: -200.0%Max.: 0.0%–n8-51(053E)Acceleration/Deceleration Pull-InCurrent (for PM Motors) PM Pull-in I@AccSets the d-Axis current reference during acceleration/deceleration as a percentage of the motor rated current. Set toa high value when more starting torque is needed.Default: 50%Min.: 0Max.: 200 –n8-54(056D)Voltage ErrorCompensation TimeConstant PM V Error CompTAdjusts the value when hunting occurs at low speed. If huntingoccurs with sudden load changes, increase n8-54 in incrementsof 0.1. Reduce this setting if oscillation occurs at start. Increasethis setting if vibration occurs at start.Default: 1.00 sMin.: 0.00Max.: 10.00 –n8-55(056E) Load InertiaPMLoad wk2 Ratio0: Less than 1:101: 1:10 to 1:302: 1:30 to 1:503: More than 1:50Sets the ratio between motor and machine inertia.0: Below 1:101: Between 1:10 and 1:302: Between 1:30 and 1:503: Beyond 1:50Default: 0Min.: 0Max.: 3 –n8-57(0574) High FrequencyInjectionPM Harm Inj Sel0: Disabled1: Enabled0: Disabled. Disable when using an SPM motor.1: Enabled. Use this setting to enhance the speed control rangewhen using an IPM motor.Default: 0Range: 0, 1 –n8-62(057D) Output Voltage Limit(for PM Motors) PM Vout LimitPrevents output voltage saturation. Should be set just below thevoltage provided by the input power supply. Default: 200.0 V<4>Min.: 0.0Max.: 230.0 <4>–n8-65(065C)Speed FeedbackDetection Control Gainduring ov Suppression SFdbk G @OV Supp Sets the gain used for internal speed feedback detection duringov suppression. Default: 1.50Min.: 0.00Max.: 10.00 –n8-69(065D) Speed Calculation Gain SpdSrch GainSets the proportional gain for PLL control of an extendedobserver.There is normally no need to change this parameter from thedefault value.Default: 1.00Min.: 0.00Max.: 20.00 –n8-72(0655)<1>Speed EstimationMethod SelectionSpd Est method0: Conventional1: A1000 methodSets the method to be used for estimating the speed.0: Conventional method1: A1000 methodThere is normally no need to change this parameter from thedefault value.Note: This parameter is not available in models4A0930 and 4A1200.Default: 1Range: 0, 1 –n8-84(02D3)Initial PolarityEstimation TimeoutCurrent Polarity Det CurrSets the current to determine polarity for the initial polaritycalculation as a percentage of the motor rated current.100% = Motor rated currentNote: If an “Si” value is listed on a Yaskawa motornameplate, set n8-84 to “Si” value x 2.Default: 100%Min.: 0Max.: 150 –<1> Available in drive software versions PRG: 1018 and later.<2> Default setting is determined by parameter n8-72, Speed Estimation Method Selection.When n8-72 = 0, default is 50.0When n8-72 = 1, default is 150.0.<3> Default setting is determined by parameter E5-01, Motor Code Selection.<4> Values shown are specific to 200 V class drives. Double the value for 400 V class drives. Multiply the value by 2.875 for 600 V class drives.B.9 n: Special AdjustmentYASKAWA ELECTRIC TOEP C710616 41G YASKAWA AC Drive - A1000 Quick Start Guide 311B Parameter List
