Parameter Details1111.3 b: ApplicationYASKAWA ELECTRIC SIEP C710617 01B YASKAWA AC Drive GA700 Technical Manual 611This setting starts operating the drive at the minimum output frequency when the Run command is entered.The drive will execute Speed Search and begin operating the motor when the Run command is enabled while theExternal Speed Search command 1 or 2 [H1-xx = 61, 62] is input from a multi-function input terminal.1 : EnabledThis setting performs Speed Search when the Run command is entered. The drive begins running the motor afterSpeed Search is complete.■ b3-02: Speed Search Deactivation CurrentNo.(Hex.) Name Description Default(Range)b3-02(0192)Speed SearchDeactivation Current Sets the current level that ends Speed Search as a percentage of the driverated output current. Normally there is no need to change this setting.Determined by A1-02(0 - 200%)Lower this setting if the drive is unable to restart the motor.■ b3-03: Speed Search Deceleration TimeNo.(Hex.) Name Description Default(Range)b3-03(0193)Speed SearchDeceleration Time Determines the deceleration time during Speed Search operation. Set thetime it takes to decelerate from the maximum output frequency to theminimum output frequency.2.0 s(0.1 - 10.0 s)This is the output frequency deceleration time used by Current Detection Speed Search and by the CurrentInjection Method of Speed Estimation Speed Search.Note:Lower the value set in b3-03 if oL1 [Motor Overload] is triggered when executing Current Detection Speed Search.■ b3-04: V/f Gain during Speed SearchNo.(Hex.) Name Description Default Setting(Range)b3-04(0194)V/f Gain duringSpeed Search Configures the ratio used to reduce the V/f during searches to reduce theoutput current during speed searches.Determined by o2-04(10 - 100)Use the following expression to calculate the output voltage during speed searches.Output voltage during speed searches = Configured V/f × b3-04This configuration is unnecessary if the current detection search operates correctly.■ b3-05: Speed Search Delay TimeNo.(Hex.) Name Description Default(Range)b3-05(0195)Speed Search DelayTime If a magnetic contactor is installed between the drive and the motor, thisparameter sets a delay time to activate the magnetic contactor by delayingSpeed Search.0.2 s(0.0 - 100.0 s)In cases where a magnetic contactor is used between the drive and the motor, the contactor must be closed beforethe drive can perform Speed Search. This parameter sets a delay time to activate the magnetic contactor in suchcases.■ b3-06: Speed Estimation Current Level 1No.(Hex.) Name Description Default Setting(Range)b3-06(0196)Speed EstimationCurrent Level 1 Configure the amount of current that flows to the motor as a coefficient ofthe motor rated current when executing the Speed Estimation Speed Search.Normally there is no need to change this setting.Determined by o2-04(0.0 - 2.0)V/f CL-V/f OLV CLV AOLV OLV/PMOLV/PM AOLV/PM CLV/PM EZOLVV/f CL-V/f OLV CLV AOLV OLV/PMOLV/PM AOLV/PM CLV/PM EZOLVV/f CL-V/f OLV CLV AOLV OLV/PMOLV/PM AOLV/PM CLV/PM EZOLVV/f CL-V/f OLV CLV AOLV OLV/PMOLV/PM AOLV/PM CLV/PM EZOLVV/f CL-V/f OLV CLV AOLV OLV/PMOLV/PM AOLV/PM CLV/PM EZOLV
