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
for information about the differences between HD and ND ratings.
