LimGen X axis In
The x axis input to the Limit Generator. Typically this
parameter is linked to a speed reference or to parameter 201
[Time Axis Output].

Limit Gen Hi Out
Indicates the positive output of the Limit Generator. When
parameter 206 [Limit Gen X Axis In] is greater than or equal to
1, this value equals parameter 204 [Limit Gen Y axis Mx].
When parameter 206 [Limit Gen X Axis In] is equal to 0, this
value equals parameter 205 [Limit Gen Y axis Mn]. For values
of x Axis input between 0 and 1, the value of this parameter is
interpolated from Y axis min and max values. Typically it is
linked to parameter 188 [PI High Limit].

Limit Gen Lo Out
Indicates the negative output of the Limit Generator. The value
of this parameter is the negative of parameter 207 [Limit Gen
Hi Out]. Typically it is linked to parameter 189 [PI Lower Limit].

PeakDtct Ctrl In
Sets configuration of the two peak/level detectors.
• Set mode is a level detector which causes the output to
match the preset when the input exceeds the preset.
• Hold mode is a level detector which causes the output
to match the input, the moment it detects the input
exceeding the preset.
• Regular peak detection (when set and hold are off)
causes the output to match the input at the moment a
peak is detected.
• Sel determines if the peak/level detector is positive of
negative. If the bit is set the detector detects positive
peaks or levels above the preset. If the bit is not set
the detector detects negative "valleys" or levels below
the preset.

Status of peak/level detectors. A peak detector sets its bit
when it detects a peak or when its input exceeds its preset -
