Drive Duty Modes

The drive has two duty modes from which to select for the application: Heavy Duty (HD) and Normal Duty (ND).
Note:
The drive has two duty modes from which to select for the application: Heavy Duty (HD1/2) and Normal Duty (ND1/2). When E1-01
[Input AC Supply Voltage] ≥ 460 V, the duty rating switches to HD2 or ND2. The specifications listed here are different between HD1
and HD2 and ND1 and ND2.
• The input power kVA
• The maximum applicable motor output
• The rated input current
• The rated output capacity
• The rated output current
The rated output current of HD/ND is the reference to set the parameter as a percentage of the drive rated output
current. Refer to Table 10.1
