Note:
Set C5-50 = 0 [Notch Filter Frequency = 0 Hz] to disable the notch filter.
◆ 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 “Model-Specific Specifications“ for more
information about the rated output current.
Note:
Duty rating changes when E1-01 [Input AC Supply Voltage] changes. When E1-01 < 460 V, the duty rating is HD1 or ND1. When E1-
01 ≥ 460 V, the duty rating is HD2 or ND2. When E1-01 ≥ 460 V, the load characteristic level automatically changes from HD1 to HD2
or from ND1 to ND2.

Load
Characteristics
Application
A high overload tolerance is necessary during start up, acceleration,
deceleration, and equivalent conditions.
• Extruder
• Conveyor
• Cranes and hoists
• Constant torque or high overload capacity are necessary.
Overload tolerance is not necessary.
• Fan
• Pump
• Blower
