| Output voltage adjustment (Base frequency voltage) |
|
|
| |||||
| The |
| parameter adjusts the voltage corresponding | to the base frequency 1 | so that no | ||||
|
| ||||||||
| voltage exceeding the |
| set value is put out. (This function is enabled only when | is | |||||
|

| Supply voltage correction |
|
|
|
|

| The | parameter maintains a constant V/F ratio, even when the input voltage decreases. The | |||||||
torque during
Supply voltage correction .............. Maintains a constant V/F ratio, even when the input voltage fluctuates.
Output voltage adjustment ............. Limits the voltage at frequencies exceeding the base frequency. Applied
| when operating a special motor with low induced voltage. |

✩If 
is set to "0" or "3", the output voltage will change in proportion to the input voltage.
✩Even if the base frequency voltage (
parameter) is set above the input voltage, the output voltage will not exceed the input voltage.
✩The rate of voltage to frequency can be adjusted according to the rated motor capacity. For example,
setting 
to " 
" or " 
" prevents the output voltage from increasing, even if the input voltage changes when operation frequency exceeds the base frequency.
