Drive Duty and Carrier Frequency Selection: C6-01 and C6-02

n Drive Duty Selection: C6-01
The drive has two different duty modes from which to select based on the load characteristics.
The drive rated current, overload capacity, and carrier frequency will change depending upon
the duty mode selection. Use parameter C6-01 (Duty Cycle) to select Heavy Duty (HD) or
Normal Duty (ND) for the application. The default setting is ND.
