Heavy Duty and Normal Duty Ratings

The capacity of the drive is based on two types of load characteristics: Heavy Duty (HD) and Normal Duty (ND).
Refer to Table A.1 for the differences between HD and ND. Specifications for capacity ratings appear are listed on the following pages.

<1> The following pages list information on rating changes based on drive model.
HD and ND
TERMS TERMS
• HD refers to applications requiring constant torque output, while ND refers to applications with variable torque needs.
• The drive allows the user to select HD or ND torque depending on the application. Fans, pumps, and blowers should use ND (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 less obtrusive white noise.
Note: Differences between HD ratings and ND ratings for the drive include rated input and output current, overload capacity, carrier frequency, and current limit. The default setting
is for ND (C6-01=1).
