Internal homing control logic
for position-controlled cranes can also done with
ready-made parameters. These include integrated speed match,
speed monitor, fast stop, slowdown and end limit logic. The position measurement
enables position actual signals millimeters for further
logic.

3A FE68404592 REV 3.
This control program designed for different kinds of
crane motions mainly for hoist, trolley and long travel
motions. The motor
control software specially made for permanent
m agnet low -speed high-torque motors.
The load speed control enables optimization the
hoist speed for different loads.
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. Permanent magnet control program
supports adaptive programming with blocks using
standard program and with the system program. The benefits provided include enhanced
equipm ent protection, optimised fluid production, and
overall improvement system performance.
The ABB crane control program flexible control

.
An easy-to-use, ready-made solution specifically for
cranes. Brake acknowledge, torque
memory and pre-magnetisations are the key software
elements that ensure reliable control. Adaptive
programming with blocks gives additional flexibility
for tailor-made modifications outside the ready-made
parameter structure.
The integrated service counters for aintenance logic
enable the different counters provide information.7.
