ABB ACS380 Series - Fault Functions

200 Parameters
30.30 Overvoltage control Enables the overvoltage control of the intermediate DC
link. Fast braking of a high inertia load causes the voltage
to rise to the overvoltage control limit. To prevent the DC
voltage from exceeding the limit, the overvoltage
controller automatically decreases the braking torque.
Note: If the drive is equipped with a brake chopper and
resistor, or a regenerative supply unit, the controller must
be disabled.
Enable
Disable Overvoltage control disabled. 0
Enable Overvoltage control enabled. 1
30.31 Undervoltage control Enables the undervoltage control of the intermediate DC
link. If the DC voltage drops due to input power cut off, the
undervoltage controller will automatically decrease the
motor torque in order to keep the voltage above the lower
limit. By decreasing the motor torque, the inertia of the
load will cause regeneration back to the drive, keeping the
DC link charged and preventing an undervoltage trip until
the motor coasts to a stop. This will act as a power-loss
ride-through functionality in systems with high inertia,
such as a centrifuge or a fan.
