Three-phase current balance
coefficient
Read-only, the calibration factor
of three-phase current balance
coefficient will automatically
change. The synchronous motor
may trigger the self study
command of the asynchronous
motor to output contactor, and
carry out the calibration of the
three-phase current balance
coefficient. Such function will
reduce the motor vibration and
improve comfort.
Positive /negtive rotation enabled
0:allow Positive /negtive rotation
1:only allow positive rotation
Position /negtive rotation
dead-time
The zero-speed time of
positive/negative rotation change
Accelerating overcurrent threshold
of inverter
Inverter stop accelerating and
maintain the current speed if
overcurrent occur during the
acceleration process, then
continue to accelerate once the
current drop.
decelerating overvoltage threshold
of inverter
Inverter stop decelerating and
maintain the current speed if bus
voltage is more than the setting
value during the deceleration
process, then continue to
decelerate once the voltage drop.
When F245=3, F246~F255 have the following meanings
Current loop Kp (no need to
modify)
Current loop Ki(no need to
modify)
Current loop Kd(no need to
modify)
When F245=4, F246~F255 have the following meanings
Rated current of inverter current
sensor
