Cd06
Motor current rate (Settable range 25~100)
Set motor overload protective current, in order to avoid motor failure because of
overload. Set value=100, please calculate the following formula:
Set Value = Motor rated current / Inverter rated current
×
100
Ex. Use inverter with 3.7KW(5HP) to drive motor with 2.2KW(3HP)
Inverter rated current = 17.4A
Motor rated current = 8A
Set Value = 8 / 17.4
×
100 = 46%
§
Cd07
Torque compensation Vb (Settable range 0~150)
The function cannot be modified during revolution.
This function is to raise output voltage to increase torque of motor.
It can also be used to increase load slope of low voltage produced by long wiring
between inverter and motor, as well as fluid, fan and pump.

Cd08, 09, 10, 11
Acceleration / deceleration time (Settable range 0.1~6000)
The time needed for set frequency from 0Hz to 50Hz.
There are 2 selections for each of acceleration time and deceleration time.
To set acceleration/deceleration time
Set Value (T) = (50 - 0) /

T1
T1: time needed for accelerate / decelerate

F: frequency changed
Ex.: Frequency from 50Hz down to 30Hz, needed time 1 sec. Then:
Set Value (T) = 50 / 50 - 30
