P2.3.12.3 Speed Reference Interpolator TC ID1184

Set here time on what interval speed reference is updated. This function ramps the

reference between updated values.

Function is used when PLC is updating reference e.g. 100 ms time level but drive own

ramp is set much shorter to have fast response. When reference (Green) is used without

interpolator also output frequency would behave same way causing torque and current

spikes every time reference changes. When interpolator time is set to 100 ms output

frequency behaves as blue line.
