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 HD (C6-01 = 0).
