9.4 Closed-loop control system

9.4.1 Parameter setting
(1) set parameter F8.01～F8.06 according to rated value of the inverter.
(2) F3.00=1: setting channel selection，here PID closed loop run control is
effective.
(3) F3.01=1: setting channel selection，here choose VCI as provision channel of
PID adjustor.
(4) F3.02=1: feedback channel selection，here choose CCI as feedback channel,
4-20mA/0-10V feedback signal.
(5) F3.08-F3.10, set according to spot requirement.
9.4.2 Basic wiring diagram
3 phase breaker
power supply
forward run
reverse run
provision signal 10K
0-10V feedback signal
9.4.3 Realized function
(1) The inverter can adjust output automatically according to feedback signal to
make 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.
9.4.4 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..
