4-2 Function Mode •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. 4 •The operation to return to normal varies depending on the setting of DC injection braking power A054. Functions 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).
