Appendix C Application Notes
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 may 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
first set of parameters is active until the speed specified in Par 184 [Adaptive Spd
1] or Par 183 [Adap Ref ] is reached.
Parameters 186 [Adaptive Joint 1] and 187 [Adaptive Joint 2] ensure a smooth
transition between the different parameter sets. The fields must be defined so
that [Adaptive Joint 1] and [Adaptive Joint 2] do not overlap.
When the adaptive speed regulator is enabled, parameters 87 [Spd Reg Kp] and
[Spd Reg Ki] parameters have no effect on the speed regulator. They do, however,
retain their value and are active when the adaptive speed regulator is disabled.
