Starting Torque
Note:
• Correctly select the drive and motor capacity for this starting torque in these control methods:
–OLV
–CLV
–AOLV
–AOLV/PM
–CLV/PM
• Set n8-57 = 1 [HFI Overlap Selection = Enabled] for this starting torque in AOLV/PM. When you use a non-Yaskawa PM motor, do Rotational
Auto-Tuning.
• V/f: 1:40

• OLV: 1:200
• CLV: 1:1500
• AOLV: 1:200
• OLV/PM: 1:20
Speed Control Range
• AOLV/PM: 1:100
• CLV/PM: 1:1500
• EZOLV: 1:100
Note:
• Set n8-57 = 1 [HFI Overlap Selection = Enabled] for this Speed Control Range in AOLV/PM. When you use a non-Yaskawa PM motor, do
Rotational Auto-Tuning.
• Speed control range of 1:100 for AOLV/PM is Instantaneous operation range. Correctly select the drive and motor capacity for continuous operation.
Possible in these control methods:
• CLV
Zero Speed Control
• AOLV/PM
• CLV/PM
