ParameterMAC mini iH Series Parameter・Expansion ManualPRM510 [ NAME ] Speed Loop Gain[ MESSAGE] P100 SPEED LOOP GAIN【DATA UNIT】 : 0.1Hz【DATA RANGE】 : 10~20000DescriptionSets the responsibility of servo motor to control speed.Corresponds to the parameter Pn100 of servo pack SGDS made by YASKAWA ELECTRICCORP.PRM511 [ NAME ] Speed Loop Integration Time Constant[ MESSAGE] P101 SLG INTEGRATION【DATA UNIT】 : 0.01msec 【DATA RANGE】 : 15~51200DescriptionThis is the user constant to determine the responsibility of speed loop.Corresponds to the parameter Pn101 of servo pack SGDS made by YASKAWA ELECTRICCORP.Precautions 1. When the responsibility of speed loop is low, since the position loop on outsidebecomes a delay factor, overshoot occurs or vibration speed command occurs.Therefore, it is recommended to set the value as higher as possible at area that themachine system does not vibrate. As a result, the servo system is stable and theresponsibility is increased.PRM512 [ NAME ] Position Loop Gain[ MESSAGE] P102 POS LOOP GAIN【DATA UNIT】 : 0.1/sec 【DATA RANGE】 : 10~20000DescriptionThe responsibility of position loop is determined by the position loop gain.Corresponds to the parameter Pn102 of servo pack SGDS made by YASKAWA ELECTRICCORP.Precautions 1. When the position loop gain can be set to high value, the responsibility becomeshigh and the positioning time becomes short. However, it is impossible to increasethe position loop gain over a natural frequency.PRM513 [ NAME ] Moment Ratio of Inertia[ MESSAGE] P103 INERTIA RATIO【DATA UNIT】 : %【DATA RANGE】 : 1~20000DescriptionWhen fixture carried in rotary table , the case where work is large, and the center of gravityhave shifted, vibration and roar sound may occur in rotary table .Load inertia of motor shaft conversion (J L )Inertia ratio =×100(%)Rotor inertia of servo motor (J M )Corresponds to the parameter Pn103 of servo pack SGDS made by YASKAWA ELECTRICCORP.P1-48 KITAGAWA
