Rockwell Automation SP600 AC Drive User Manual Version 1.0 - Manual (Page 149)

Parameter Descriptions 12-19
Sets the high limit for the speed reference after scaling is applied.
See figure 12.7.
Sets the incremental amount of the output frequency (above
Maximum Speed) allowable for functions such as slip
compensation. See figure 12.7.
Maximum Speed (82) + Overspeed Limit (83) must be ≤ to Maximum Frequency (55)
82 Maximum Speed
Range: 5.0 to 400.0 Hz [0.0 Hz]
Default: 50.0 or 60.0 Hz (dependent on voltage class)
Access: 0 Path: Speed Command>Spd Mode & Limits

!
ATTENTION: The user is responsible for ensuring
that driven machinery, all drive-train mechanisms,
and application material are capable of safe
operation at the maximum operating speed of the
drive. Overspeed detection in the drive determines
when the drive shuts down.
See figure 12.7 . Failure
to observe this precaution could result in bodily
injury.
83 Overspeed Limit
Range: 0.0 to 20.0 Hz [0.1 Hz]
Default: 10.0 Hz
