Yaskawa CIMR-PU2A0081 [240/548] Increase this setting in steps of 0 if overvoltage occurs as a result of a regenerative load when overvoltage suppression is enabled l3 11 1 decrease l3 21 in steps of 0 5 if there is a fairly large speed ripple when overvoltage suppression is enabled
No. Name Setting Range Default
L3-21 Accel/Decel Rate Calculation Gain 0.10 to 10.00 1.00
Adjustment for Single Drive KEB 2 (L2-29 = 1) and Intelligent Stall Prevention During Deceleration
Reduce L3-21 in steps of 0.05 if there is a fairly large speed or current ripple.
Small reductions of L3-21 can help solve problems with overvoltage and overcurrent.
Decreasing this setting too much can cause slow DC bus voltage control response and may also lengthen deceleration times
beyond optimal levels.
Adjustment for Overvoltage Suppression
Increase this setting in steps of 0.1 if overvoltage occurs as a result of a regenerative load when overvoltage suppression is
enabled (L3-11 = 1).
Decrease L3-21 in steps of 0.05 if there is a fairly large speed ripple when overvoltage suppression is enabled.

L3-23: Automatic Reduction Selection for Stall Prevention during Run
Reduces the Stall Prevention during run level in the constant power range.
No. Name Setting Range Default
L3-23 Automatic Reduction Selection for Stall Prevention During Run 0, 1 0
Setting 0: Disabled
The level set in L3-06 is used throughout the entire speed range.
Setting 1: Enabled
The Stall Prevention level during run is reduced in the constant power range. The lower limit will be 40% of L3-06.

L3-24: Motor Acceleration Time for Inertia Calculations
Sets the time to accelerate the motor from stop to the maximum speed at motor rated torque. Set this parameter when using
Single
Drive KEB 2 (L2-29 = 1), Intelligent Stall Prevention during Deceleration (L3-04 = 2), or the Overvoltage Suppression
function (L3-11 = 1).
No. Name Setting Range Default
L3-24 Motor Acceleration Time for Inertia Calculations 0.001 to 10.000 s
Determined by o2-04
<1>
<1> Parameter L3-24 is defaulted for a Yaskawa standard 4-pole motor. During Auto-Tuning, L3-24 will be initialized to a Yaskawa standard 4-pole
motor if parameter E2-11 is changed.

L3-25: Load Inertia Ratio
Determines the ratio between the rotor inertia and the load. Set this parameter when using Single Drive KEB 2 (L2-29 = 1),
Intelligent Stall Prevention during deceleration (L3-04 = 2), or the overvoltage suppression function (L3-11 = 1).
No. Name Setting Range Default
L3-25 Load Inertia Ratio 1.0 to 1000.0 1.0
When set incorrectly, a fairly large current ripple can result during Single Drive KEB 2 (L2-29 = 1). This may cause overvoltage
suppression (L3-11 = 1) or other faults such as ov, Uv1, and oC.
