Parameters 241
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.

31.02 External event 1 type Selects the type of external event 1. Fault
(95.20 b8)
Fault The external event generates a fault. 0
Warning The external event generates a warning. 1
Warning/Fault If the drive is modulating, the external event generates a
fault. Otherwise, the event generates a warning.
