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 name switches to
[Normal Duty 2 Rating]
or
[Heavy Duty 2 Rating]
when
E1-01 [Input AC
Supply Voltage] ≥ 460 V
.
Refer to
for information about the differences between HD and ND ratings.
