2006 UNDERVOLT
CTRL
Activates or deactivates 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 speed in order to keep the voltage above the lower
limit. By decreasing the motor speed, the inertia of the load
will cause regeneration back into the drive, keeping the DC
link charged and preventing an undervoltage trip until the
motor coasts to stop. This will act as a power-loss ride-
through functionality in systems with a high inertia, such as
a centrifuge or a fan. See section Motor identification on
page 137.
