• The value will be set in 0.01-Hz increments if the frequency is less than 100 Hz and 0.1-Hz increments
if the frequency is 100 Hz or over.

6-10-9 UP/DOWN Command Frequency Memory (n100)
• This function changes the reference frequency by turning the UP and DOWN commands ON and OFF.
• In order to use this function, set n056 for multi-function input 7 to 34. Then the multi-function input 6
(S6) and multi-function input 7 (S7) terminals are set as described below.
Multi-function input 6 (S6): UP command
Multi-function input 7 (S7): DOWN command
• The output frequency held by the UP/DOWN function will be stored in the memory if n100 for UP/
DOWN frequency storage is set to 1.
• By setting n100 to 1, the frequency reference kept on hold for 5 s or more will be retained even after a
power interruption, and operation will be restarted at this frequency the next time the RUN command is
input.
• The stored output frequency will be cleared from the memory if n100 is set to 0. The retained frequency
is initialized if n001 for parameter initialization is set to 8 or 9.
Note While this function is used, frequency references can only be used in remote mode with the UP/
DOWN command or inching frequency command. All multi-step speed references are disabled.
