以下是科比F5B（基本型）变频器说明书的一部分，

Max .ramp current
This function protects the frequency inverter against switching off through overcurrent during the acceleration ramp. When the ramp reaches the adjusted value .It is stopped so long until the current decreases again. CP3. displays “AS” at active function

Max .constant current
This function protects the frequency inverter against switch off through overcurrent during constant output frequency .When exceeding the adjusted value. the output frequency is reduced until the drops below the adjusted value. CP3. displays “SSL” at active function

Max .ramp current 就是电流限幅？是？？

Max .constant current 是恒流？是？？
