Speed Command File (File C)

No. Parameter Name and Description
080 [Speed Mode]
Sets the method of speed regulation.
081 [Minimum Speed]
Sets the low limit for speed reference after
scaling is applied.
Refer to parameter 083 [Overspeed Limit].
082 [Maximum Speed]
Sets the high limit for speed reference
after scaling is applied.
Refer to parameter 083 [Overspeed Limit].
083 [Overspeed Limit]
Sets the incremental amount of the output
frequency (above [Maximum Speed])
allowable for functions such as slip
compensation.
[Maximum Speed] + [Overspeed Limit]
must be ≤ [Maximum Freq]
