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.
