FUNCTION C
ODES
F04, F05
F06
Base Frequency 1, Rated Voltage at Base Frequency 1, Maximum Output
Voltage 1
H50, H51 (Non-linear V/f Pattern 1, Frequency and Voltage)
H52, H53 (Non-linear V/f Pattern 2, Frequency and Voltage)
These function codes specify the base frequency and the voltage at the base frequency
essentially required for running the motor properly. If combined with the related function
codes H50 through H53, these function codes may profile the non-linear V/f pattern suitable
for the load by specifying increase or decrease in voltage at any point on the V/f pattern.
The following descriptions include setups required for the non-linear V/f patterns.
At high frequencies, the motor impedance may increase, resulting in an insufficient output
voltage and a decrease in output torque. To prevent this problem, use F06 (Maximum Output
Voltage 1) to increase the voltage. Note, however, that the inverter cannot output voltage
exceeding its input power voltage.
