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