• Use this function to set the upper and lower limits of the output frequency. The set limits will be
applied if the input frequency reference is beyond the upper/lower limit(s).
• Set the upper limit first. Be sure that the value set in the 1st/2nd Frequency Upper Limit (A061/A261)
must be larger than the value set in the 1st/2nd Frequency Lower Limit (A062/A262).
• Set the upper and lower limit values so that they do not exceed the 1st/2nd/3rd Maximum Frequency
(A004/A204/A304).
• Set the Output Frequency Setting/Monitor (F001) and the Multi-step Speed Reference 1 to 15 (A021
to A035) whithin the upper and lower limit settings.
• The upper/lower limit setting is disabled when 0 Hz is set.
