n24
Maximum Frequency
Setting range
Unit of setting 50.0 to 99.9 (Hz) : 0.1 (Hz)
n25
Maximum Voltage
Setting range
Unit of setting 1 (V)
n26
Maximum Voltage Frequency (Basic Frequency)
Setting range
Unit of setting 1.6 to 99.9 (Hz) : 0.1 (Hz)
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.
