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.
