Hi, does anyone here know anything about ABBs direct torque control drives. ie what is it. Regards Alan Case
I believe all Finnish in origin. I think they have designed and manuf. in Finland and some models in Milwaukee (New Berlin) for US market.DickDV said:I believe all Swiss in origin.
I have used ACS600 for Roll Lift. Earlier Lifters ware hydraulic, but they do not like 'oil' in the paper mill floor, so El.-Motor is better for that. Starting from zero speed needs magnetism in motor before Brake can opened, otherwise lifter lowering a little in the start. I understand many more thinks now, thanks Dick ! I hope you understand my english.Originally posted by DickDV
I've seen but never done hoisting systems that use DTC to stop and hold a load in midair using nothing but zero-speed motor torque to hold it.
