33
The inverter will come into closed-loop run mode when closed –loop run control
effective parameter is set(F3.00=1). Namely carry on PID adjustment to specified
value and feedback value(proportion integral differential calculation，see F3 group
function code) and PID adjustor output is inverter output frequency. Can make
closed-loop run mode ineffective and switch to lower level run mode by
multi-function terminal (function 20).
2: PLC run
The inverter will enter into PLC run mode and run according to run mode
preset(see F4 group function code description) through setting PLC function
effective parameter(F4.00 last bit≠0). Can make PLC run mode ineffective and
switch to lower level run mode by multi-function terminal (function 21).
3: multi-section speed run
By nonzero combination of multi-function terminal(1, 2, 3, 4 function)，choose
multisection frequency 1~7(F2.30~F2.36) to run at multisection speed.
4: swing frequency run
The inverter will enter into swing frequency run mode when swing frequency
function effective parameter(F6.00=1)is set. Set relevant swing frequency run
special parameter according to textile swing frequency craft to realize swing
frequency run.
5: common run
Common open loop run mode of general inverter.
In above 6 kinds of run mode except “jog run” the inverter can run according to
kinds of frequency setting method. In“PID run”“PLC run”“multisection run”
“common run”mode the inverter can also carry on pendular frequency
adjustment.
