The position measurement
enables position actual signals millimeters for further
logic. The benefits provided include enhanced
equipm ent protection, optimised fluid production, and
overall improvement system performance.
Permanent magnet synchronous motor
(PMSM) control program
This control program available with standard control
application and system control application. This offers
precise and reliable control low speed without
speed feedback.7.
An easy-to-use, ready-made solution specifically for
cranes. The motor
control software specially made for permanent
m agnet low -speed high-torque motors.
The integrated service counters for aintenance logic
enable the different counters provide information.
■ Integrated decanter control for the accurate speed
difference control two shafts, here direct com
munication via the fibre optic link betw een bowl
and scroll used. Fast switchover logic betw een
stand-alone and master-follower logic increases the
operational productivity.
Crane control program
safety and performance.
The ABB crane control program flexible control
platform, hich enables wide range connectivity
for start, stop and reference logic.
This control program designed for different kinds of
crane motions mainly for hoist, trolley and long travel
motions. These include integrated speed match,
speed monitor, fast stop, slowdown and end limit logic.
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. This like having small PLC
inside the drive.2009 Application software and programming 51
.
Centrifuge control program
■ Practical programmable sequences for conventional
centrifuges. Permanent magnet control program
supports adaptive programming with blocks using
standard program and with the system program. Brake acknowledge, torque
memory and pre-magnetisations are the key software
elements that ensure reliable control.
■ Centrifuge control program supports adaptive pro
gramming with blocks.Optional control programs
Control solutions for different applications
products not only increase the production and pump
efficiency, but also reduce the stress the com plete
pump system. Internal homing control logic
for position-controlled cranes can also done with
ready-made parameters.
Reliable, integrated brake control logic for smooth open
and close logic without jerks improves operational
3A FE68404592 REV 3.
The load speed control enables optimization the
hoist speed for different loads.
Different functions standard increase the safety level
of the crane. Adaptive
programming with blocks gives additional flexibility
for tailor-made modifications outside the ready-made
parameter structure
