3-6-3 Maximum Output Frequency
• This parameter functions as a frequency limiter.
• Acceleration and deceleration times are defined as the times required to reach the maximum output
frequency (P06) from 0 Hz and to reach 0 Hz from the maximum output frequency (P06).
Note The setting unit for the frequency reference upper and lower limits is 0.1 Hz for less than
100 Hz, and 1 Hz for 100 Hz or higher.
3-6-4 Setting Frequency Reference Upper and Lower Limits
• Upper and lower limits are set for the frequency reference input from the Digital Operation, fre-
quency references 1 to 4, time-proportional pulse inputs, or communications.
• If the frequency reference lower limit (P08) is higher than the frequency reference upper limit (P07),
operation will be at the frequency lower limit.
• If the frequency reference upper limit (P07) or frequency reference lower limit (P08) is set higher
than the maximum output frequency (P06), the maximum output frequency will be used for the fre-
quency reference upper limit or frequency reference lower limit. (The settings will be automatically
replaced when RUN mode is entered.)
Note The setting unit for the frequency reference upper and lower limits is 0.1 Hz for less than 100
Hz, and 1 Hz for 100 Hz or greater.
