<1> Upper limit is dependent on parameter L8-38, Frequency Reduction 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.
<4> Parameter value changes automatically if E2-11 is manually changed or changed by Auto-Tuning.
<5> Default setting is dependent on parameter o2-04, Drive Model Selection.

7: Overexcitation Deceleration 3. Applies more braking power
than normal overexcitation deceleration. Yaskawa recommends
extra caution due to the heavy load on the motor.

Sets the desired value for the DC bus voltage during overvoltage
suppression and Stall Prevention during deceleration.
DC Bus Reg Level
Sets the proportional gain for KEB Ride-Thru, Stall Prevention,
DC Bus P Gain and overvoltage suppression.
Sets the proportional gain used to calculate the deceleration rate
Acc/Dec P Gain during KEB Ride-Thru, ov suppression function, and Stall
Prevention during deceleration (L3-04 = 2).

Sets the time needed to accelerate the uncoupled motor at rated
torque from stop to the maximum frequency.
Mtr Accel Time
Sets the ratio between the motor and machine inertia.
