    the acceleration time when multi function input emergency stop is on.0:unit:0.01 second 1:unit:0.1 second.note:to set more precisely the acceleration time,please set c 1_10 to be 0. but the setting range in narrow.

    set the frequency for automatic acceleration/switching below set frequency acceleration/deceleration time 4.above set frequency.acceleration/deceleration time 1
    note:please set the frequency point in the situation where automatic switching of accelerating/deceleration is needed.if the acceleration/deceleration time
    selector 1 and 2 are input via the multi function inputs,they will have priority.
    c 2-01 s-curve characteristic time at acceleration start setting range is 0.0~2.50 and factory setting is 0.20. c 2-02 s-curve characteristic time at acceleration end setting range is 0.00~2.50 and factory setting is 0.20.the s-curve characteristic is set in unit of second.
    using the s-curve characteristic function for acceleration and deceleration can reduce shock to the machinery when stopping and starting. with the inverter s-curve characteristic times can be set respectively for beginning acceleration ending acceleration beginning deceleration,and ending deceleration. when the s-curve characteristic time is set the acceleration and deceleration times will be lengthened as follows, acceleration time= selected acceleration time + (s-curve at beginning of acceleration + s-curve at end of acceleration)/2 . deceleration time =selected deceleration





    this constant is used to adjust the responsiveness of droop control.

    note : it is constant to adjust the responsiveness of droop control . please increase the gain value in the situation with vibration.setting range is 0.03~2.00.factory setting is 0.05.


    set the inverters output voltage when the energy saving command is given.setting range is 0~100
    factory setting is 80.change during operation is x.control methods.v/f =a.v/f with loop.vector=x.flux vector=x

    note: when the energy saving command is given , please set the inverter,s output voltage in unit of % with the set voltage of v/f curve taken as 100% . to set the voltage change according to voltage recovery time under the command of on off.


    two types of pid control are possible with the inverter: measured_value derivation pid control and basic pid control .the types that is normally use is measured _value derivation pid control . with measured value derivative pid control . the feedback value is differentiated for pid control response is possible with respect to changes bot in target values and the control object.
    basic pid control : this is the basic form of pid control ,when the d control response is adjusted to follow changes in the control object , overshooting and undershooting can occur with changes in the target value . to enable pid control .


    make a setting between  1  to  4 (normally 2 or  4 is used for measured value derivative pid control ). when pid control is effective the target value can be selected as any of the following . if setting the target value input as  b 1-01=0 (digital operator ),set the 01-03 to  , 1 , (% unit) and input a percentage value for the target value . (when the speed reference is changed ,100 % becomes the maximum frequency reference ).the input value from analog input terminal 3 is the pid target value .  input from multi function analog input terminal 16  (h 3 -05 = c ) or terminal 14 (h 3 – o 9 =c),when the input value of analog input terminal is the pid target value, it can be adjusted by setting the gain and basic of the analog .


    to set the output width of zero servo completion signal , multi  function input is set be effective when zero servo is completed. zero servo completion signal,s output in current position (zero servo start position+/ – zero servo completion width ) is on . the delay value from zero servo starting position to admissible position is set by 4 times of plus quantity of pg (plus encoder ).setting range is 0~16383 ,factory setting is 10. flux vector is A

    any of the multi function inputs (h 1- 01–06) is allocated to zero servo command. the set value is 72. when frequency (speed) command is below zero speed level (b 2 – 0 1 ),it will be zero servo status. if the operation command,s input is still (on),off, the output will be cut, and the loss ends.the lock strength of zero servo depends on (b 9 – 0 1 ).


    zero servo gain .the bigger the set of  b 9 – 0 1  is , the bigger the lock strength is , please adjust the lock strength after adjusting the speed control (a s r ) gain. when zero servo is output to the exterior , any of the constant among multi function output (h 2- 01~03) is set be to zero servo completion width  (value is 33). then zero servo completion  width (b 9 -0 2)is set be too effective . zero servo ending signal is in position of on with in the range of zero servo starting position +/ – zero servo completion width .


    the delay value from zero servo starting position to admissible position is set by 4 times of pulse quantity of pg (pulse encoder). set the allowable position displacement from  rate of the pg (pulse generator, encoder ) in the use for instance:for the encoder width 600 p/r four times of pulse quantity is 2400/r. if  function, please avoid long time servo lock with 100% load , otherwise , it will result in inverters fault, please increase the power level of inverters when the servo retentiveness current drops to 10%.


    pid feedback loss detection time is to be set in unit  of second.

    dwell frequency at start
    dwell function is to maintain the output frequency at a certain value for a while the heavy load is started or stopped . to dwell the output frequency for some time can avoid stall out . the relations among these constants is as show in below.
    b 6  – 0 3  dwell frequency at stop setting rang is 0,0~10,0 , frequency setting is 0.0


    set the slip as percentage of the slip at maximum frequency and rated torque .
    note: slip (the slip at maximum output frequency and rated torque ). in unit of %.droop is disable when set as 0.0. b 7- 02  setting range is 0.0~100.0 factory setting o.o




    it sets the timer function output off delay timer (dead band)for the timer function input in unit of second .

    note : enabled when the timer function is est for multi function inputs and outputs .  Enabled when  function input (setting :18) and the output (setting :12)are set for the multi function input and output respectively. these input and outputs serve as general purpose 1/0.chattering of sensors, switches, and so on ,can be prevented by setting a delay time . the timer function input off time is longer than the value set for b 4 -02  ,the timer function output turns off.

    1. What i do not understood is actually how you’re not really much more well-liked than you may be now. You’re very intelligent. You realize thus significantly relating to this subject, made me personally consider it from a lot of varied angles. Its like women and men aren’t fascinated unless it’s one thing to accomplish with Lady gaga! Your own stuffs excellent. Always maintain it up!

    2. obviously like your web site but you have to check the spelling on several of your posts. Several of them are rife with spelling issues and I find it very troublesome to tell the truth nevertheless I’ll definitely come back again.
