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 Selecting the Appropriate Load Rating on page 156
HD and ND. Specifications for capacity ratings are listed on the following pages.

<1> The following pages list information on rating changes based on drive model.
• HD and ND: 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).
