Omron Sysdrive RX Series - Frequency Limit

4-28
4-2 Function Mode
4
Functions
•If the RUN command is turned on with the frequency reference established (or a value larger than
the A052 setting is input), the initial operation is set to normal output.
•The operation to return to normal varies depending on the setting of DC injection braking power
A054.
Frequency Limit
•You can set both the upper/lower limits to the output frequency.
* To switch to the 2nd/3rd control, allocate 08 (SET)/17 (SET3) to the desired multi-function input and then turn it
on.
•Does not accept any frequency reference beyond the upper/lower limits.
•Set the upper limit first. Make sure that the upper limit (A061/A261) is larger than the lower limit
(A062/A262).
