In the occasion where up/down was set multi step peed command 1~8 will be all non effective . the dwell output frequency when up/down is on will be memorized by the value of d4-01 (dwelling function option of frequency command) the setting value is 1 . the value will be recorded after the power is cut and the operation will start from this frequency after the operation command is input again . this recorded output frequency is in status of off under the operation command , once up command or down command ( see the below time sequence of up command / down command ) is in the status of on the recorded output frequency will be eliminate.

Off = normal operation .
On = fault reset at the rising edg of on, (operation will be normal when fault does not occur ) .
It is used to reset the fault from exterior . when fault occurs please find out the fault content and take the right solution then restart the inverter . if you do not take any solution and reset the fault the verger could be damaged . when fault occurs turn off the operation command turn on the fault reset and turn on the operation command again then it will come back to the previous status the reset can not be affected in the occasion where operation command is on  . when no fault occurs the switch between on/off of this signal won,t affect the operation .It is the function to control the inverter,s output frequency through the control terminal,s on/off . when using this function please make sure to set the 2 multi function input up/down command .if only to set single multi function input the fault ope 03 will occur .besides in the occasion where acceleration /deceleration stop was both set (value a) ope 03 fault will occur too. b1-02  operation method selection  please set it to be 1 (exterior terminal ) it won,t act except when it is set 1 . frequency ,s up/down to mimes or plus the time normally )c1-01 ~08 ).frequency up/down . when up/down , output frequency ,s upper limit and lower limit will be set as follows ,upper limit , maximum output frequency (e1-04) output frequency upper limit (d2-01)/100 .
lower limit maximum output frequency ( e1-04) output frequency command (current ) terminal 14 are input as used as frequency command input the maximum frequency value will be taken as the lower limit ,(up , down are both on /off status except that the operation command is on ) . when up/down function is used once the operation command is input the output frequency will be accelerated till it teaches the lower limit .  when up/down function and job frequency selection is selected at multi function input at the same time jog frequency option on has the priority  to be selected

One thought on “winner inverter fault setting”
  1. I just couldn’t depart your website before suggesting that I extremely enjoyed the standard information a person provide for your visitors? Is going to be back often to check up on new posts
