During deceleration, the GS4 drive DC bus voltage may exceed its Maximum Allowable Value due
to motor regeneration. When this function is enabled, the GS4 drive will stop decelerating, and
maintain a constant output frequency. The drive will resume deceleration when the voltage drops
below the factory-preset value.

NOTE: With moderate inertial loads, over-voltage during deceleration should not occur.
For applications with high inertia loads, the GS4 drive will automatically extend the
deceleration time. If deceleration time is critical for the application, a dynamic braking
resistor should be used. Set this parameter to 1 (disable) when using a dynamic braking
resistor.
