242 Parameters
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.
Disable
Undervoltage control disabled.
0
Enable
