Kinda Single Phase Variable Frequency Drive applied in carving machine
(2) It needs high torque at low speed.
2, Requests for frequency inverters (VFD)
(1) Wide range of operation frequency.
(2) It needs multi-points V/f carve, which can control the output
torque at different speed.
(3) An external input ON/OFF signal will be used to start and stop
the frequency inverter, an external input analog signal will be
used
to control the output frequency and it needs fault reset input
signal and fault output signal.
3, Instruction for commissioning
(1) Pictures of carving machine
(2) Parameters list
Take 400Hz, 380V and 24000RPM carving machine as example.

(3) Typical wiring diagram
4, Notices
(1) To ensure the over current fault will not happen, the
multi-points V/f setting in F4 group should be set base on real
requests, the
voltage points and frequency points should follow the rule of
V/f1< V/f2< V/f3, and the voltage at low frequency cannot be
set too
big.
(2) The motor’s parameters on the nameplate of carving machine
should be set correctly in F2 group.
