6-7-7 UP/DOWN Command Frequency Memory (n62)
•
This function changes the reference frequency by turning the UP and DOWN com-
mands 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 be-
low.
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 frequency hold function selector 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.
