Sets the incremental amount of the output frequency (above Maximum Speed)
allowable for functions such as slip compensation. See Figure 38
.
Maximum Speed + Overspeed Limit must be ≤ to Maximum Frequency.

Sets a frequency at which the drive will not operate (also called an avoidance
frequency). Requires that both Skip Frequency 1...3 and Skip Frequency Band
(87) be set to a value other than 0.
