[Traverse Dec]

Sets the time period of decreasing frequency. Setting this
parameter to zero disables the traverse function.

[Bus Regulation]

Enabling this parameter causes the drive to adjust output
frequency based on the DC bus voltage. If the drive senses
rising bus voltage, it will increase the output frequency to
reduce the regenerative energy from the motor that is
causing the bus voltage to rise. This will reduce the risk of
an overhauling load causing an Overvolt Fault.

[Load Loss Detect]

This parameter enables the function that detects an
indicated loss of load on the motor. A fault (F20) or alarm
condition will occur if [Torque Current] falls below [Load
Loss Level] for a time period greater than [Load Loss
Time].
