*1 The default setting changes when the setting for o2-04 [Drive Model Selection] changes.
*2 Drive models 2211 to 2415 and 4103 to 4720 use these default settings when C6-01 = 1 [Normal / Heavy Duty Selection = Normal Duty
Rating]. Drive models 2257 to 2415 and 4140 to 4720 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 the setting of C6-01 [Normal / Heavy Duty Selection] changes.
*4 The setting range varies depending on the setting of E5-01 [PM Motor Code Selection] when A1-02 = 5 [Control Method Selection = PM
Open Loop Vector].
*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 within the setting range is 100.0 when A1-02 = 5 or 7 [Control Method Selection = PM Open Loop Vector or PM
Closed Loop Vector].
*8 The setting range is -100.0 to 100.0 when A1-02 = 5 or 7 [Control Method Selection = PM Open Loop Vector or PM Closed Loop
Vector].
◆ A1-02 = 5 to 8 [Control Method for PM Motors and EZ Vector Control]
