Overvoltage LAD Stop Function
• This function helps avoid an overvoltage trip of the Inverter due to regenerative energy from the
motor during deceleration.
• Select to enable or disable the overvoltage LAD stop function in b130.
• Adjust the overvoltage LAD stop function level in b131.
• The main circuit DC voltage rises because of regenerative energy from the motor once
deceleration starts. With the overvoltage LAD stop function enabled (b130 = 1), the Inverter stops
deceleration temporarily once the main circuit DC voltage has reached the overvoltage LAD stop
level, which is lower than the overvoltage level. Deceleration then resumes if the voltage level falls
below the overvoltage LAD stop level.
• With the overvoltage LAD stop function enabled (b130: 01), the actual deceleration time becomes
longer than the set value (F003/F203).
• This function does not aim to keep the main circuit DC voltage level constant. Therefore, an
overvoltage trip may occur if the main circuit DC voltage rises rapidly because of rapid
deceleration.
