Voltage is double for 400 V class drives.*5 When using Closed Loop V/f Control, ASR controls only the output frequency, so unlike Closed Loop Vector Control, a high-gainsetting cannot be made.◆ Open Loop Vector Control MethodWith Open Loop Vector Control method, C4-01 [Torque Compensation Gain] should be left at its default setting(1.00). Do not adjust it.If speed accuracy cannot be obtained during regeneration when using Open Loop Vector Control method, set C3-04 = 1 [Slip Compensation @ Regen Select = Enabled above 6 Hz].
