Drive Duty Modes
The drive has two duty modes from which to select for the application: Heavy Duty (HD) and Normal Duty (ND).
The duty rating switches to HD2 or ND2 when E1-01 [Input AC Supply Voltage] ≥ 460 V. These specifications are
different between HD1/HD2 and ND1/ND2:
• The input power kVA
• The maximum applicable motor output
• The rated input current
• The rated output capacity
• The rated output current
Refer to
Table 12.1
for information about the differences between HD and ND ratings.
