the detailed method of three-phase current sensor calibration is as following: first of
all, find the asynchronous motor self-study mode in the adjustment menu of the
portable operator, press the confirmation key and the integrated unit will output the
KMY closing command to make the contactor closed. Then the operator will display
“studying” for 30 seconds while conducting three-phase current sensor
self-calibration. The operator will display “study complete” when study successfully.
At this time set the F245 to 2, and obverse the F250 to be the value between 800 and
1200 (1000 not allowed). The default value of F250 is 1000. The value can not be
1000 after self-study. Otherwise, redo the self-study until the correct value is
obtained.
F252—— 0:allow Positive /negtive rotation 1:only allow positive rotation
F253—— The zero-speed time of positive/negative rotation change
F254—— accelerated over-current threshold of frequency converter. Acceleration will stop if
current exceed the setting value during the process of the acceleration. And current
speed is maintained. Acceleration will resume after the current drop.
F255—— decelerated over-voltage threshold of frequency converter. Deceleration will stop if
busbar voltage exceeds the setting value during the process of the deceleration. The
current speed is maintained. Deceleration will resume after the voltage drop.
When F245=3
F246—— the integral P of current loop PID adjuster, no adjustment needed.
F247—— the integral I of current loop PID adjuster, no adjustment needed.
F248—— the integral D of current loop PID adjuster, no adjustment needed.
F254—— Torque direction 0:positive 1:negative
When F245=4
F246—— Software version code. Read-only parameter
F247—— ID NO 0. Read-only parameter
F248—— ID NO 1. Read-only parameter
F249—— ID NO 2. Read-only parameter
F250—— ID NO 3. Read-only parameter
F251—— ID NO 4. Read-only parameter
F252—— ID NO 5. Read-only parameter
F253—— rated current of the integrated unit, read-only parameter.
F254—— rated current of the integrated unit current sensor, Read-only parameter.
F255—— Motor power coefficient Set the max power output, generally do not need to change
When F245=5
F246—— Stator resistor. The stator resistor of asynchronous motor
F247—— rotor resistance. Rotor resistance of asynchronous motor
F248—— Stator inductor. The stator inductor of asynchronous motor
F249—— rotor inductor. The rotor inductor of asynchronous motor
F250—— Mutual inductor. The mutual inductor of asynchronous motor
F251—— Motor low-speed over current threshold. When the motor speed is lower than the 20%
rated speed, motor stop and motor low-speed over current reported when the current
exceed the setting value and the over current time duration exceed that set by the
F252.
