<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).

0: Disabled.
1: General purpose. Acceleration is paused as long as the current
is above the L3-02 setting.
2: Intelligent. Accelerate in the shortest possible time without
exceeding the L3-02 level.

3: StallP +Resistor
4: High Flux Brake
5: High Flux Brake2
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.
2: Intelligent. Decelerate as fast as possible while avoiding ov
faults.
3: Stall Prevention with braking resistor. Stall Prevention during
deceleration is enabled in coordination with dynamic braking.
4: Overexcitation Deceleration. Decelerates while increasing
the motor flux.
5: Overexcitation Deceleration 2. Adjust the deceleration rate
according to the DC bus voltage.
Note:
Setting 3 is not available in models 4A0930 and
4A1200.
