safety and performance. Adaptive
programming with blocks gives additional flexibility
for tailor-made modifications outside the ready-made
parameter structure.
■ Integrated decanter control for the accurate speed

Permanent magnet synchronous motor
(PMSM) control program
This control program available with standard control
application and system control application.
■ Centrifuge control program supports adaptive pro
gramming with blocks. Fast switchover logic betw een
stand-alone and master-follower logic increases the
operational productivity. The benefits provided include enhanced
equipm ent protection, optimised fluid production, and
overall improvement system performance. Permanent magnet control program
supports adaptive programming with blocks using
standard program and with the system program.
Centrifuge control program
■ Practical programmable sequences for conventional
centrifuges.
The load speed control enables optimization the
hoist speed for different loads.
This control program designed for different kinds of
crane motions mainly for hoist, trolley and long travel
motions.
The integrated service counters for aintenance logic
enable the different counters provide information. The position measurement
enables position actual signals millimeters for further

Control solutions for different applications
products not only increase the production and pump
efficiency, but also reduce the stress the com plete

The master-follower logic for five motors enables
com drum separate motors with load sharing,
or with separate drums and separate motors with
shaft synchro control. Brake acknowledge, torque
memory and pre-magnetisations are the key software
elements that ensure reliable control. These include integrated speed match,
speed monitor, fast stop, slowdown and end limit logic. The motor
control software specially made for permanent

Different functions standard increase the safety level
of the crane. This like having small PLC
inside the drive.
Reliable, integrated brake control logic for smooth open
