Up/Down Command Frequency Memory (N62) - Omron SYSDRIVE 3G3JV Series User Manual

Advanced Operation

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.
