12.4 C: Tuning536 YASKAWA SIEPC71061753A GA500 Technical Manual■ C5-29: Speed Control ResponseNo.(Hex.) Name Description Default(Range)C5-29(0B18)ExpertSpeed Control ResponseSets the level of speed control responsiveness. Usually it is not necessary to change this setting.1(0, 1)If a high level of speed control responsiveness is necessary, set C5-29 = 1, then adjust the speed control (ASR)parameter.0 : Standard1 : High Performance 1■ C5-39: ASR Primary Delay Time Const 2No.(Hex.) Name Description Default(Range)C5-39(030D)ASR Primary Delay TimeConst 2 Sets the filter time constant used when the torque reference is output from ASR. Usually it is notnecessary to change this parameter.0.000 s(0.000 - 0.500 s)If you have a load with low rigidity or if oscillation is a problem, increase this setting in 0.01 unit increments.◆ C6: Duty & Carrier FrequencyC6 parameters are used to set the selection of drive duty rating, selection of carrier frequency, and upper andlower limits of carrier frequencies.■ C6-01: Normal / Heavy Duty SelectionNo.(Hex.) Name Description Default(Range)C6-01(0223)Normal / Heavy DutySelection Sets the drive duty rating.0(0, 1)0 : Heavy Duty RatingThe overload tolerance is 150% of the rated output current for 60 seconds.1 : Normal Duty RatingThe overload tolerance is 110% of the rated output current for 60 seconds.There are two types of load ratings for this product depending on the load characteristics of the application: HeavyDuty Rating (HD) and Normal Duty Rating (ND).The drive rated output current, overload tolerance, and acceleration stall prevention level change when the dutyrating changes. Set the drive to agree with the duty rating of the selected drive capacity. In HD, the tolerance is150% overload for 60 seconds. In ND, the tolerance is 110% overload for 60 seconds. The rated output current forND drives is higher than the rated output current for HD drives.
