Are the higher frequency CPUs ever required when purchasing a PMAC?
For Turbo , we would recommend the 100mhz CPU for: -more than 12 axes uncommutated, -more than 8 axes -Servo update rate over 8kHz -Block (programmed move ) or segment rates over 500 Hz Recommendations for the 160 MHz: -More than 24 axes uncommutated -More than 16 axes commutated -Servo update rate greater than 15kHz -Block or segment rates over 1000kHz -2 of the 100 MHz requirements simultaneously If there is any doubt, we recommend that the prototyping is done with the fastest CPU available, then try running it at lower speeds.
