Function Parameters
Detailed instruction of parameters
low-speed running.
Times of motor overload M = Iout/(In*K)
In is the rated current of the motor, Iout is the output current
of the inverter and K is the motor protection coefficient.
So, the bigger the value of K is, the smaller the value of M is.
When M =116%, the fault will be reported after 1 hour, when
M =200%, the fault will be reported after 1 minute, when
M>=400%, the fault will be reported instantly.
Setting range: 20.0%~120.0%
P04 Group
This function code defines the V/F curve of CV10 inverter to
meet the need of different loads.
0: Straight line V/F curve, applying to the constant torque
load
1: Multi-dots V/F curve
Torque boost to the output voltage for the features of low
frequency torque. P04.01 is for the Max. Output voltage V
P04.02 defines the percentage of closing frequency of
manual torque to f .
b
Torque boost should be selected according to the load. The
bigger the load is, the bigger the torque is. Too big torque
boost is inappropriate because the motor will run with over
magnetic, and the current of the inverter will increase to add
the temperature of the inverter and decrease the efficiency.
When the torque boost is set to 0.0%, the inverter is
automatic torque boost.
Torque boost threshold: below this frequency point, the
