Defines the minimum speed (rpm) allowed.
• A positive (or zero) minimum speed value defines two ranges,
one positive and one negative.
• A negative minimum speed value defines one speed range.
• See figure.

Sets the DC undervoltage controller on or off. When on:
• If the DC bus voltage drops due to loss of input power, the undervoltage controller decreases the motor speed in
order to keep the DC bus voltage above the lower limit.
• When the motor speed decreases, the inertia of the load causes regeneration back into the drive, keeping the DC
bus charged, and preventing an undervoltage trip.
• The DC undervoltage controller increases power loss ride-through on systems with a high inertia, such as a
centrifuge or a fan.
