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.
