124 YASKAWA ELECTRIC TOEP C710616 21C YASKAWA AC Drive - A1000 Quick Start GuideA SpecificationsA Specifications◆ Heavy Duty and Normal Duty RatingsThe capacity of the drive is based on two types of load characteristics: Heavy Duty (HD) and Normal Duty (ND).Refer to Selecting the Appropriate Load Rating on page 124 for the differences between HD and ND.Table 59 Selecting the Appropriate Load RatingNote: Differences between HD ratings and ND ratings for the drive include rated input and output current, overload capacity, carrierfrequency, and current limit. The default setting is for HD (C6-01 = 0).Setting ParameterC6-01<1> Refer to Three-Phase 200 V Class Drives on page 125 and Three-Phase 400 V Class Drives on page 126 for information on rating changesbased on drive model.Rated Output Current Overload Tolerance Default Carrier Frequency0: Heavy Duty(default) HD Rating varies by model <1> 150% rated output current for 60 s 2 kHz1: Normal Duty ND Rating varies by model <1> 120% rated output current for 60 s varies bymodel 2 kHz, Swing PWMTERMSTERMSTERMS HD and ND: HD refers to applications requiring constant torque output, while ND refers to applications with variable torqueneeds. The drive allows the user to select HD or ND torque depending on the application. Fans, pumps, and blowers should useND (C6-01 = 1), and other applications generally use HD (C6-01 = 0).Swing PWM: Swing PWM equivalent to a 2 kHz audible noise. This function turns the motor noise into a lessobtrusive white noise.
