*1 The default setting changes when the setting for o2-04 [Drive Model Selection] changes.
*2 Models 2211 to 2415, 4103 to 4720, and T103 to T720 use these default settings when C6-01 = 1 [Normal / Heavy Duty Selection =
Normal Duty Rating]. Models 2257 to 2415, 4140 to 4720, and T103 to T720 use these default settings when C6-01 = 0 [Heavy Duty
Rating].
• A1-02 = 2 [Open Loop Vector]: 2.00
• A1-02 = 3, 4 [Closed Loop Vector, Advanced Open Loop Vector]: 0.05
*3 The default setting changes when C6-01 [Normal / Heavy Duty Selection] changes.
*4 The maximum value changes when A1-02 changes:
• When A1-02 = 0, 2 [V/f Control, Open Loop Vector], the maximum value is 590.0 Hz.
• When A1-02 = 1, 3 [V/f Control with Encoder, Closed Loop Vector], the maximum value is 400.0 Hz.
• When A1-02 = 4 [Advanced Open Loop Vector], the maximum value is 120.0 Hz.
*5 The default setting changes when the drive model and E1-03 [V/f Pattern Selection] change.
*6 This is the value for 200 V class drives. Double the value for 400 V class drives.
*7 The maximum value changes when A1-02 changes:
• When A1-02 = 0, 2 [V/f Control, Open Loop Vector], the maximum value is 590.0 Hz.
• When A1-02 = 1 [V/f Control with Encoder], the maximum value is 400.0 Hz.
• When A1-02 = 4 [Advanced Open Loop Vector], the maximum value is 120.0 Hz.
*8 The minimum value changes when A1-02 changes:
• When A1-02 = 0, 2 [V/f Control, Open Loop Vector], the minimum value is -590.0 Hz.
• When A1-02 = 1, 3 [V/f Control with Encoder, Closed Loop Vector], the minimum value is -400.0 Hz.
• When A1-02 = 4 [Advanced Open Loop Vector], the minimum value is -120.0 Hz.
