tomake constant voltage, constant temperature, constant current etc. available.
(2) can control start/stop of the motor from long distance.
(3) bear failure alarm and current indicator function.
10.4.4 Application field
Applied in field where need stable system, pressure, flux such as blower pump,
constant pressure water supply, air compressor, air conditioner, freezer cooling
tower, music fountain, heat supply etc..
10.5 Consecutive action running
10.5.1 Basic wiring diagram
Fig.10-5
10.5.2 Parameter setting
set 1# inverter as follows:
(1) F0.00=6: YCI analog setting is frequency provision for 1# inverter.
(2) F0.02=1orF0.02=2: terminal run command control.
(3) F2.15=0:the 1#inverter will be setted as mainframe run.
set 2# inverter as follows:
(1) F0.00=3: serial port specified.
(2) F0.02=3or F0.02=4: serial port running command control.
(3) F2.15is setted between 1to 127,the 2#inverter will become the mainframe.
After above setting, can use serial communication of 1# inverter to
realizeconsecutive action of 2# inverter.
10.5.3 Operation description
After receive forward run command from external switch(closed) and
frequency specified value(0~10V)from analog input terminal YCI, 1# inverter run
at this frequency value. At the same time, already running state of 1# inverter，
make 2# inverter get forward run command through serial communication，here，
run frequency value from high-speed pulse output terminal of 1# inverter is
