■ Setting example: for automatic dwell operation
Set <F350: Acc suspended frequency>, <F352: Dec suspended frequency>, <F351: Acc
suspended time>, and <F353: Dec suspended time>. Then set <F349: Dwell operation> to "1".
When the output frequency reaches the set frequency, operation will automatically switch to
constant speed run (acceleration/deceleration suspended).
■ Setting example: for dwell operation by external signal input
Assign function numbers "60", "61" (dwell operation) to the unused input terminal.
Dwell operation will be performed while the input terminal is ON.
When you set run command ON after you set the dwell operation signal ON, operation will start at
<F240: Start frequency>.
Important
• When output frequency falls due to the stall preventive function, dwell operation may be
enabled.
