440 VOLT ( ELECTRONIC ) INVERTER,S CONSTANT FUNCTION INTRODUCTION.



IN OPERATION 2 (SETTING :37)

Off = inverter has no output frequency  baseblock, dc brake, initial excitation .
On = inverter has frequency output .

MOTOR,S  OVERLOAD  OLI  PRE  ALARMING  (SETTING ,1F)

Off = the electronic thermal protection value of the motor protection is less than 90% of the detection level .
On = the electronic thermal protection value of the motor protection is above 90% of the detection level .

adopting electronics thermo sensor  it is effective only when motor,s overload protection function is effective (l1-01) .
it can be used as overheat pre alarming prior to the protection function .

PRELIM OF INVERTER OVERHEAT OH ,( SETTING :20 ) .

Off = the cooling fan,s temperature is less than the value of l8-02 .
On = the temperature of the cooling fan is above the value of l8-02 .

ZERO SERVO ENDS ( SETTING :33 ) .

Off = zero servo  command is not input  or zero servo control position is not finished .
On = the position has been brought within the zero servo completion width (b9-02) after the zero servo command was input .

To output whether zero servo position control ends or not . The  position has been brought within the zero servo completion width (b9-02) after the zero servo command was input .

SIGNAL LEVEL SELECTION (TERMINAL 13 )( H3-01) .

Frequency command (voltage ) terminal 13 ,s  signal level setting 0:0~+ 10 volt (11 bit + polarity  positive / negative ) input 1:0~+- 10 volt   when the voltage is negative  it becomes the operation command with direction opposite to the commanded operation direction .
Note : frequency command ( voltage ) it is effective when b1- 01 ( frequency command selection) is set to be 1 . to set the signal level of frequency command ( voltage ).

GAIN TERMINAL  13 (H3-02) .

Set the frequency at 10 voltage in unit of % with max , output frequency taken as 100% .
please see h3 -11 .
