[SpdReg AntiBckup]
Allows control of over-shoot/under-shoot in the step response of the speed
regulator. Over-shoot/under-shoot can be effectively
eliminated with a setting of 0.3, which will remove backup of the motor shaft
when zero speed is reached. This parameter has no affect on the drive's
response to load changes. A value of zero disables this feature.
Note: This parameter was added for firmware version 4.001.
