16 Centrifuge program features unloading speed and a discharger removes the product from the basket. An alternative unloading method allows top removal of product in a filter bag. Operating mode Centrifuge operation can be set with parameter 74.01 Centrifuge/ Decanter function selection.
• To start or stop the Centrifuge through I/O controls, select the source of start and stop commands separately for each control location (EXT1 or EXT2) with parameters 20.01...20.10. See ACS880 primary control program firmware manual (3AUA0000085967[English]). • Use the I/O controls only when the drive is in external control mode. The “Local” on the first row of the panel indicates local control.
The program can contain a maximum of 30 blocks. The adaptive program is executed on a 10 ms time level. For more information, see • ACS880 primary control program firmware manual (3AUA0000085967[English]) • Adaptive programming application guide (3AXD50000028574 [English]).

Decanter features The main features of Decanter drive are: •...
20 Decanter program features Decanter Operation Decanter operating principle The Decanter control fulfills the common requirement of two-shaft decanters, where the machinery consists of a bowl and a scroll (screw conveyer). Slurry input Bowl Gear Solids output Liquid output Screw (scroll) Figure 6.
Decanter program features 21 Decanter control modes The three basic control modes of Decanter are: Local control, Speed reference control and Decanter control. Local control This mode is selected using the LOC/REM key on the panel. The “Local” is visible on the first row of the panel display.
22 Decanter program features Decanter process load compensation The load compensation of Scroll drive enables compensating the process load variations of a Decanter. This means that, it is possible to influence the quality of the end product automatically through a differential speed correction. See the below chain diagram and parameters 78.17 Load compensation gain 78.18 Load compensation int...
Decanter program features 23 78.14 Torque reference 78.15 Torque gain 78.16 Torque integration time 78.19 Torque to delta speed See also Decanter control chain diagram of Scroll drive on page 24. Direct torque compensation The operating principle of the direct torque compensation is based on actual torque compensation of the Scroll drive.
Decanter program features 25 Decanter examples The below examples depict the mechanical and electrical configuration of a Back drive and Forward drive in a Decanter/Centrifuge application. Back drive, variant A Decanter Centrifuge Bowl Scroll Gearbox Scroll motor Bowl motor Main drive Back drive Supply network...
Decanter program features 27 Since Scroll motor is directly coupled to gearbox, parameters corresponding to D3 and D4 (belt roller diameter) must be set to 1. The communication between Scroll drive and Bowl drive is maintained through DDCS (M/F) link. Bowl drive parameter settings: 78.01 Decanter mode select = Bowl...
28 Decanter program features If Bowl motor is rotating in the forward direction, Scroll motor must also be rotating in the forward direction. This can be achieved by setting the parameters in Group 78 Decanter control. D1 and D2 are Bowl and Scroll motor drives as represented in the above figure. Since Scroll motor is directly coupled to gearbox, the parameters corresponding to D3 and D4 (belt roller diameter) must be set to 1.
