Adjust and Function Specification
§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.

Output Frequency (HZ)
§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) / △F ×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 ×1 = 2.5
Cd08 = Acceleration time
Cd09 = Deceleration time
Cd10 = 2
