ELECTRIC INVERTER carrier frequency is 2 k Hz . 1:carrier frequency is the setting of c 6-0 1. 2: carrier frequency is 5 k Hz electric inverter carrier frequency of the inverter of 400 v is 2.5 Hz ) 185 ~ 300 kw .normally electric inverter is not necessary to change this setting , fine , tune the gain when motor operation is unstable causing hunting to occur or torque / speed responsiveness is low . when hunting occurs, increase the gain by 0.05 increments while checking the motor responsiveness. when responsiveness is low decrease the gain by 0.05 increments while checking the motor responsiveness.
AFR TIME.
it is used to set speed feedback detection control (AFR) gain in unit of multiples .
CARRIER FREQUENCY SELECTION DURING AUTO TUNING .
0: carrier frequency ,2 k Hz.
1: carrier frequency is the set value of constant (c 6-0 1).
2: carrier frequency is 5 k Hz (the ca carrier frequency of the inverter of 400 v is 2.5 Hz )185~300 kw NOTE:it is used to set speed feedback detection control (AFR) gain in unit of multiples.
FREQUENCY REFERENCE.
1: sets the frequency reference in the units used in 01-03 (frequency reference display/ set units,)the factory setting unit for 01-03 is Hz.
2: the frequency reference when the multi, function input multi step speed reference 1 is on , (the unit is set be 01-03).
3: the frequency reference when the multi function input multi step speed reference 2 is on (the unit is set be 01-03) .
4:the frequency reference when the multi function input multi step speed reference 1, 2 is on .(the unit is set be 01-03).
5: the frequency reference when the multi function input multi step speed reference 3 is on ,(the unit is set be 01-03)
6: the frequency reference when the multi function input multi step speed reference 1, 3 , is on ,(the unit is set be 01-03).
7: the frequency reference when the multi function input multi step speed reference 2, 3 , is on (the unit is set be 01-03).
8: the frequency reference when the multi function input multi step speed reference 1 , 2 , 3 is on ( the unit is set be 01-03)
HUNTING PREVENTION SELECTION.OF ELECTRIC INVERTER
0:DISABLED
1:ENABLED
NOTE: THE HUNTING PREVENTION FUNCTION IS USED TO STOP A MOTOR UNDER A LIGHT LOAD FROM HUNTING . THIS FUNCTION IS EXCLUSIVELY FOR THE V/F CONTROL MODE, WHEN GREATER RESPONSIVENESS THAN OSCILLATION CONTROL IS REQUIRED SET HUNTING PREVENTION TO ,DISABLED
.
HUNTING PREVENTION GAIN.
SETS THE RATIO FOR HUNTING PREVENTION GAIN.
NOTE: INCREASE THE SETTING IN C 7-0 2 OSCILLATION OCCURS WHEN OPERATING WITH A LIGHT LOAD . (IF THE SETTING IS INCREASED TOO MUCH , THE CURRENT CAN FALL TO THE POINT WHERE STALLING OCCURS,). DECREASE THE SETTING IN C 7-0 2 IF STALLING OCCURS DISABLE THE HUNTING , PREVENTION FUNCTION (C 7- 0 1=0) IF HIGH RESPONSIVENESS IS MORE IMPORTANT THAN SUPPRESSING OSCILLATION.
Wow, incredible weblog format! How lengthy have you been running a blog for? you make running a blog look easy. The entire look of your web site is wonderful, as smartly as the content material!
This design is spectacular! You most certainly know how to keep a reader amused. Between your wit and your videos, I was almost moved to start my own blog (well, almost…HaHa!) Excellent job. I really loved what you had to say, and more than that, how you presented it. Too cool!
