(Veichi Electric Technical Service Department)
(Note 1: This maintenance manual related circuit diagrams, using the AC310 series
2.2KW machine as a reference, the control board screen printing diagrams and other
power segments of the power board different points, in the appendix will be prompted,
the appendix according to each power segment circuit is divided into 3 power segments,
each power segment select a specific power segment.
There will be tips in the appendix, the appendix according to the different circuits in
each power section, roughly divided into three power sections, each power section to
select a specific power as a practical example to explain the differences and similarities,
details.
(Note 2: AC310 general-purpose AC drive is still in the process of continuous
optimisation of the hardware circuit, so sometimes there may be inconsistencies
between the specifications of the actual components and the specifications on the circuit
diagram.
(Note 3: This service manual involves hardware design circuit diagrams, and should
not be distributed privately.)
