Programming 5 - 30
If one of the custom V/f patterns is selected, then parameters E1-04 through E1-13 will determine the V/F pattern.
Table 3 is for 240V class units only; for 480V class unit multiply the voltage value by 2.
E1-04 Maximum Output Frequency
Setting Range: 0.0 to 120.0 Hz
Factory Default: 60.0 Hz
