The load sharing and remote control of the conveyor motors (16km for the longest conveyor) are crucial for the plant’s performance. The motors are controlled by Nidec’s GT3000 variable speed drive inverters, allowing a smooth start-up (even at full load) and sharing of torques on motors during the stop or start-up phases. The automation control system monitors production of the conveyor in order to:
– ascertain at any moment the conveyor’s sections of loaded product as well as
their percentage of charge
– control the upstream conveyor’s supply to manage the conveyor load according
to the profile
– adapt the motor sharing according to the load on the conveyor
Nidec drives, coupled with ARTICS high performance algorithms support machine output and equipment life improvement.
