§
Cd51
Motor rated voltage setting Vr (Settable range 10~450)
This function cannot be modified during revolution.
RMS Setting
A. 220V Series: Value of Cd51 = Motor rated voltage / 1
A. 380V Series: Value of Cd51 = Motor rated voltage / 1.73
B. 460V Series: Value of Cd51 = Motor rated voltage / 2
Ex.
a. If the motor rated voltage 220Vrms. Power supply voltage 220Vrms, then setting
Cd51=220/1=220, then the inverter output Vrate=220Vrms.
b. If the motor rated voltage 380Vrms. Power supply voltage 380Vrms, then setting
Cd51=380/1.73=220, then the inverter output Vrate=380Vrms.
c. If the motor rated voltage 460Vrms. Power supply voltage 460Vrms, then setting
Cd51=460/2=230, then the inverter output Vrate=460Vrms.

§
Cd52
Auto voltage compensation (settable range 0.5%~15.0%
)
The function cannot be modified during revolution.
The function is to compensate torque of motor in low r.p.m. Auto voltage compensation
parameter is to increase torque to increase output voltage
This function must accommodate the content of Cd03
