If a high level of speed control responsiveness is necessary, set C5-29 = 1, then adjust the speed control (ASR)
parameter.

C6: Duty & Carrier Frequency
C6 parameters are used to set the selection of drive duty rating, selection of carrier frequency, and upper and
lower limits of carrier frequencies.

0 : Heavy Duty Rating
The overload tolerance is 150% of the rated output current for 60 seconds.
1 : Normal Duty Rating
The overload tolerance is 110% of the rated output current for 60 seconds.
There are two types of load ratings for this product depending on the load characteristics of the application: Heavy
Duty Rating (HD) and Normal Duty Rating (ND).
The drive rated output current, overload tolerance, and acceleration stall prevention level change when the duty
rating changes. Set the drive to agree with the duty rating of the selected drive capacity. In HD, the tolerance is
150% overload for 60 seconds. In ND, the tolerance is 110% overload for 60 seconds. The rated output current for
ND drives is higher than the rated output current for HD drives. Refer to
