Strict CNC punching machine for motor power
CNC punching machine motor power is proportional to the product of current and voltage, then directly by power frequency electric consumption of power will be much higher than that of frequency conversion start needed to power. CNC punch press under some conditions the distribution system has reached the highest limit and its direct start motor power frequency generated by the surge will have a significant impact to with other online users, which will be warned by grid operators, and even a fine. If CNC punch press adopts frequency converter for motor start-stop, won't produce similar problems.
