Today's automation systems, using multiaxis mixtures of AC, DC and stepper motors, are often driven to PC controllers for faster and faster machine throughput as well as increased reliability and decreased installation costs.
I would like to know the group's feelings about the benefits of distributing the PID loop control out of the PC and into or nearby the amplifier and/or motor vs. using an integral ISA or PCI motion card in the computer itself.
Some of the issues are: reduced wiring lengths, EMI noise, processing loop time, cost of smart amplifiers vs. control boards, networking, Environmental conditions, trajectory planning time, programmability...
Some of the configurations are:
1. PCI/ISA/PC104/VME multiaxis motion cards with a single Processor providing PID and planning
2. PCI/ISA/PC104/VME multiaxis motion cards with a dsp on each axis for PID, and central
processor for planning
3. Stand alone multiaxis controllers
4. Smart Amplifiers, with digital PID filter and tuning, networked
5. Smart Motors with internal amps, networked
6. etc.
