Overspeed Error Detection

The over-speed error detection function judges that the speed is excessive if the feedback speed
exceeds the over-speed level.
This function operates when other than "0.0" is specified for [bb-80] Over-speed error detection level.
The overspeed is detected by the feedback frequencies displayed on [dA-08] speed detection monitor.
When the speed has exceeded [bb-80] Over-speed error detection level and [bb-81] Over-speed error
detection time has elapsed, it is judged as an over-speed error.
When an over-speed error occurs, the inverter trips with [E107] Over-speed error.
Precautions for Correct Use
To use this function, speed feedback by the encoder is required.

Description
Set the overspeed level at 100% to which
the maximum frequency is set.
Sets the time to judge the speed to be an
error after it has excessively increased. The
inverter trips with [E107] Over-speed error.
Displays the data obtained through encoder
feedback.
