Frequency Converter for Motorized Spindle Units
for Milling and Grinding
When selcting a drive, its current output should be over-rated by +20% for an S6 duty-cycle, and + 50% for an S1 duty-cycle, beyond the maximum draw of the motor. With frequency regulated drives, system speed governs the selction process. For optimal speed regulation, select drives with a higher frequency output than required, to minimize noise (wow and flutter), with smaller, more advantageous filtering network.
