Note The values in parentheses are for the 400-VAC class.
•
These three constants are used to set a V/f pattern.
•
Check the motor specifications and set each constant as follows:
n24: Maximum frequency or rated frequency
n25: Rated voltage
n26: Rated frequency
•
The value set in n24 (maximum frequency) must be equal to or greater than the value
set in n26 (maximum voltage frequency). Otherwise, an error will result.
