5.3 Description of Function Codes
5-58
F03
Maximum frequency 1
F03 specifies the maximum frequency that the inverter outputs. When the device to be driven is set to rated or
higher, the device may be damaged. Make sure to make an adjustment to design mode value of the machinery.
• Data setting range: 25.0 to 500.0 (Hz)
Modes Control mode Data setting range Remarks
HD/HND/HHD mode V/f control 500 Hz
ND mode V/f control 120 Hz Restricted internally.*
* When setting is performed by exceeding the maximum setting range (for example, 500 Hz), speed setting and
analog output (FMA) become input/output mode of full scale/setting value (10V/ 500Hz). However, it is internally
restricted (for example, 120Hz), therefore, even if 10V is input for setting value, the value is restricted internally
by 2.4 V (equivalent to 120 Hz), not by 500Hz.
Use function code F80 to switch between ND, HD, HND and HHD drive modes.
Inverter can perform setting of high speed operation easily. When changing the setting, make sure to check
the motor and machine mode before use.
Injuries could occur. Failure may occur.
When changing maximum output frequency (F03) in order to make the operation frequency a larger
value, change t
he frequency limiter (upper limit) (F15) as well.
