66z The factory setting for the maximum output frequency is 50Hz.When changing the maximum output frequency, set the frequency range (V/Fpattern) (parameter P03) to FF, and then change the max. output frequencysetting (parameter P15).[Example to change maximum output frequency from 50Hz to 100Hz]∗ If the frequency range is "50" or "60", the max. output frequency and base frequency will befixed.∗ When the frequency range is FF", the frequency range will be determined according tothe max. output frequency and base frequency.Note 1) A frequency exceeding the upper frequency clamp (parameter P54) cannot beoutput.Note 2) If a general-purpose motor with a rated frequency of 50 or 60Hz is run at afrequency exceeding the rated frequency, the motor may be damaged. Always setthe frequency to match the motor characteristics.Note 3) If the base frequency must be changed together with the max. output frequencyfor a high-speed exclusive motor, etc., change parameter P16 with the proceduregiven above.Note 4) When running a general-purpose motor with a frequency higher than thecommercial frequency, the base frequency will be set to the normal motor's ratedoutput frequency (50 or 60Hz).Note 5) When using the general-purpose motor at a level higher than the base frequency(normally 50 or 60Hz), the motor will enter the rated output characteristics, and thegenerated torque will drop in inverse proportion to the frequency.Changing and Setting the MaximumOutput FrequencyOutput voltage (%)Output voltage (%) Max. output frequency (P15=100)Base frequency (P16=50)Frequency(Hz)010050 100Frequency(Hz)010050(1) Change frequency range to FF(Change parameter P03 to FF)(2) Change max. output frequencyto 100Hz(Change parameter P15 to 100)Downloaded from www.Manualslib.com manuals search engine
