Voltage Output
Adjust and Function Specification
§Cd50 Software version (Read only)
This function is to record software version, read only.
§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
B. 380V Series: Value of Cd51 = Motor rated voltage / 1.73
C. 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.

Frequency Output
1. Vin ＞Vrate when Fr ＜Fb Vout = Fr / Fb ×Vrate
when Fr ＞Fb Vout = Vrate
2. Vin ＜Vrate when Vout ＜Vin Vout = Fr / Fb ×Vrate
when Vout ＞Vin Vout = Vin
Vin: Power supply voltage
Vout: Inverter output voltage
Vrate: Motor rated voltage
Fr: Inverter revolution frequency
Fb: base frequency
§Cd52 Motor no-load current setting (Settable range 5-60)
