Speed Regulation Functions The PowerFlex DC Digital drive provides a flexible speed regulator circuit that
can be adapted to the requirements of a variety of applications. The drive is set to
PI regulation by default.
Adaptive Speed Regulator
The adaptive speed regulator function enables different gains of the speed
regulator depending on the speed reference or another variable (adaptive
reference). This allows optimum adaptation of the speed regulator to the specific
application.
The adaptive speed regulator is enabled with parameter 181 [Adaptive Spd En] =
“1 Enabled”. Normally the gain depends on the speed of the drive. It can,
however, vary according to a variable defined in parameter 183 [Adap Ref ]. The
type of regulation used is selected in parameter 182 [Adaptive Reg Typ]; 0 =
“Speed”, or 1 = “Adaptive Ref ”.
Parameters 184 [Adaptive Spd 1] and 185 [Adaptive Spd 2] are used to define the
three ranges that can have different gains. A parameter set can be defined for each
of these ranges, with each set containing an individually definable P and I
component (i.e., Pars 188 [Adaptive P Gain1] and 189 [Adaptive I Gain1], 190
[Adaptive P Gain2] and 191 [Adaptive I Gain2], and 192 [Adaptive P Gain3]
and 193 [Adaptive I Gain3]). When the adaptive speed regulator is enabled, the
