Specification of high-performance vector convertor
This is the commonest wiring way. If using external power, pull out jumper J9 between +24V and
OP, connect positive pole of external power to OP and negative pole of external power to CME.
Source-type wiring way
This kind of wiring way needs to jump OP of jumper J9 to COM, connect +24V to common
port of external controller. If using external power, connect negative pole of external power to OP.
c ) DO digital output terminal: if digital output terminal needs to drive relay, absorber diode should be
installed on two sides of relay coil, otherwise DC 24V power may be damaged.
Caution: install the polarity of absorber diode correctly as shown in Figure 3-11. Otherwise, if any output
of digital output terminal, it will damage DC 24V power immediately.
