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
ratings appear are listed on the following pages.

HD and ND

TERMS 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).
