<1> Default setting is dependent on parameter o2-04, Drive Model Selection.
<2> Default setting is dependent on parameter E1-01, Input voltage Setting.
<3> Values shown are specific to 200 V class drives. Double the value for 400 V class drives. Multiply the value by 2.875 for 600 V class drives.
<4> Setting range value is dependent on parameter C1-10, Accel/Decel Time Setting Units. When C1-10 = 0 (units of 0.01 seconds), the setting range
becomes 0.00 to 600.00 seconds.
<5> Values shown are specific to 200 V class drives. Double the value for 400 V class drives. Multiply the value by 2.875 for 600 V class drives, but
set the value below 1040 Vdc (overvoltage protection level).

exceeding the L3-02 level.
Used when L3-01 = 1 or 2. 100% is equal to the drive rated
current.
StallP Accel Lvl
Sets Stall Prevention lower limit during acceleration when
StallPAcc LowLim operating in the constant power range. Set as a percentage of
drive rated current.
0: Disabled. Deceleration at the active deceleration rate. An ov
fault may occur.
1: General purpose. Deceleration is paused when the DC bus
voltage exceeds the Stall Prevention level.
