<2> Default setting is dependent on parameter E1-01, Input voltage Setting.
<3> Values shown are specific to 400 V class drives. Multiply the value by 1.4375 for 575 V class drives. Multiply the value by 1.725 for 690 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 400 V class drives. Multiply the value by 1.4375 for 575 V class drives. Multiply the value by 1.725 for 690 V class
drives.

Stall Prevention Selection
during Deceleration
All Modes
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 CIMR-Ao4A0930 and
4A1200. A1000 HHP models only have settings 0, 1, 4, and 5.
