Phenomenon
The motor speed fol-
lows the command
slowly.
The motor operates
unstably.
Overshoot and/or
hunting occur.
The motor speed oscil-
lates gently.
Stabilization of the
operation requires a
long time.
It takes time for the
command value and
the motor speed to be
equal to each other.
Precautions for Correct Use
• When the revolution of the motor is hindered by such causes as the braking or the motor lock
caused by foreign objects, such hindrance may cause over current, or the like. When no such
adjustment as ones mentioned above improves the state, checking the portion around the
motor may sometimes improves it.
• If an application of load results in a great amount of change in the inverter's output frequency
monitor [dA-01], a function to automatically change the frequencies for the overload limiting
function, the momentary-stop non-stop function, the over voltage suppression function may
work depending upon the settings of the functions.
