10.3.3 Realized function
(1) make use of external on-off quantum signal to control start/stop of the motor.
(2) make use of external on-off quantum signal to make the motor run at set
frequency.
(3) bear free stop and reset function by utilizing external on-off quantum signal.
(4) bear warning alarm and PLC run indication function.
10.3.4 Application field:
Applied in field where need frequent multi-speed adjustment to motor speed
such as toughened glass, weaving, paper making, chemical etc..
10.4 Closed-loop control system
10.4.1 Parameter setting
(1) Set parameter F8.01-F8.06 according to rated value of the motor.
(2) F3.00=1: setting channel selectionhere PID closed loop run control is
effective.
(3) F3.01=1: setting channel selectionhere choose VCI as provision channel of
PID adjustor.
(4) F3.02=1: feedback channel selectionhere choose CCI as feedback channel,
4-20mA/0-10V feedback signal.
(5) F3.08-F3.11, set according to spot requirement.
