AC/DC INVERTER,S AFR GAIN , AFR TIME, CARRIER FREQUENCY SELECTION DURING AUTO TUNING , AND FREQUENCY REFERENCE 1 TO 8



AFR GAIN.

0: carrier frequency is 2 k Hz . 1:carrier frequency is the setting of c 6-0 1. 2: carrier frequency is 5 k Hz (the carrier frequency of the inverter of 400 v is 2.5  Hz ) 185 ~ 300 kw .

NOTE:
normally it 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)
