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).
