6-7-7 UP/DOWN Command Frequency Memory (n62)
• This function changes the reference frequency by turning the UP and
DOWN commands on and off.
• In order to use this function, set n39 for multi-function inputs 4 to 34. Then
the multi-function input 3 (S4) and multi-function input 4 (S5) terminals
are set as described below.
Multi-function input 3 (S4): UP command (The value in n38 for multi-
function input 3 is ignored.)
Multi-function input 4 (S5): DOWN command
• The output frequency held by the UP/DOWN function will be stored in the
memory if n62 for UP/DOWN command frequency memory is set to 1.
• By setting n62 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 n62 is set
to 0. The retained frequency is initialized with n01 for parameter
initialization set to 8 or 9.
Note While this function is used, frequency references can be used with the UP/
DOWN command or inching frequency command. All multi-step speed
references are disabled.
