(default)
• General variable-speed
• Operating more than one motor from one drive
• When replacing the motor without motor parameter values.
OLV 2
• General variable-speed
• High precision and speed control without speed feedback
EZOLV 8
• General variable-speed
• No high precision, no speed control, and no speed feedback
◆ 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.
