◆ 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 Table 12.1 for information about the differences between HD and ND ratings.
