Overspeed
The
speed has been greater than the
setting
in F1-08 for longer than the
setting
in F1-09.
Overshooting/undershooting

occurring.
Adjust
the gain again.
The
reference speed is too high.
Check
the reference circuit and refer-

Excessive Speed Deviation
The
speed deviation has been greater
than
the setting in F1-10 for longer
than
the setting in F1-11.
The
load is too large.
Reduce
the load.
The
acceleration time and decelera-
