  • Page 47 Flottweg-SIMP-CONTROL® Set-up The special feature of the Flottweg SIMP-DRIVE® is the fact that the bowl and the scroll drives do not affect each other. Bowl speed (n) and differential speed (nDD) are controlled separately and independently of each other and they are proportional to the frequency of the corresponding converter.
  • Page 48 Flottweg-SIMP-CONTROL® Control of the scroll drive The below listed features of the controller apply irrespective of its model, e.g. as industrial controller or software component of a control programme. 2.1 Operating modes, function and selection In the operating mode Manual operation, the differential speed (output signal Y) is set directly by the operator and remains constantly at the stipulated value.
  • Page 49 60-100 % (at delivery 90%) Fixed value differential In general 75% 5-100% speed Note: The stipulated setting values relate to the controllers supplied by Flottweg. Controllers of other brands might feature a different control behaviour and thus require other settings. Flottweg...
  • Page 50 Flottweg-SIMP-CONTROL® 2.3 Information on the individual setting parameters Nominal torque value (W): In automatic operation, this parameter defines which torque shall activate the control. By changing the differential speed, the automatic control constantly tries to operate the machine at this torque. If the torque is rising, the differential speed will be increased and vice versa.
  • Page 51 Flottweg-SIMP-CONTROL® Controller parameters (Xp, Tn, Tv): The controller parameters Xp, Tn and Tv define the transient response characteristic of the controller, i.e. how intensely and how quickly the controller responds to a torque change. Proportional range (Xp): The proportional range Xp (P portion) is a reciprocal of the controller gain.
  • Page 52 Flottweg-SIMP-CONTROL® “Product feed off”: If the nominal torque value (W) is exceeded for the set value, the control switches off the product feed, to prevent the clogging of the centrifuge. The parameter is entered in percent of the set nominal torque value (W); the value should exceed the nominal torque value (W) sufficiently depending on the separation task.
