Function requirement of engraving machine
VF control is used for control mode selection, multi segment VF curve is used.
Small high-speed engraving milling machine must use terminal equipment operation as command source, multi line terminal equipment operation: there is only one forward command FWD (di1 type). The frequency source is analog setting (computer control board output 0 ~ 10VDC), only need to input frequency command Ai1 port.
The operating speed is generally 24000 rpm. The DC frequency conversion frequency of Yiming CNC machining center soft starter is 400Hz (secondary motor motor motor), the laser cutting speed is 2000 rpm. We can consider its regulation 650hz non-standard very well. Eight.
The acceleration deceleration time is generally within 20 ~ 30s according to the customer's own requirements. Due to the high speed of operation, the frequency converter with brake unit is required.
Fault signal output signal fault reset signal (di3 input) are required.
