6.19.6 Output voltage adjustment/Supply voltage correction
vlv : Base frequency voltage 1
f307 : Supply voltage correction (output voltage limitation)
 Function
Supply voltage correction: Prevent torque decline during low-speed operation.
Maintains a constant V/F ratio, even when the input voltage fluctuates.
Output voltage limitation: Limits the voltage to prevent outputting the voltage exceeding base frequency
voltage (vlv). Applied when operating a special motor with low induced
voltage.

● If f307 is set to "0" or "2" (Supply voltage uncorrected), the output voltage will change in proportion to
the input voltage.
● Even if the base frequency voltage (vlv parameter ) is set above the input voltage, the output voltage
will not exceed the input voltage.
● When the V/F control mode selection parameter () is set to any number between 2 to 6, the supply
voltage is corrected regardless of the setting of f307.
