Condition Possible cause
Various parameters are
not appropriate.
The load fluctuates
significantly.
The power supply voltage
fluctuates.
Various parameters are
not appropriate.
[Acceleration/constant
speed operation]
Various parameters are
not appropriate.
[Deceleration]
The operation to be taken
upon Digital Operator
disconnection is not
selected properly.
Remedial actions
Shift the output frequency slightly away
from the power supply frequency.
Change the value of Stabilization
Parameter (H006/H206).
Increase the motor/Inverter capacity.
Suppress the fluctuation.
Increase the value of Manual Torque Boost
Voltage (A042/A242) or Manual Torque
Boost Frequency (A043/A243).
Set Torque Boost Selection (A041/A241)
to "01: Automatic torque boost".
Decrease the Carrier Frequency (b083).
Set Control Method (A044/A244) to "03:
Sensorless vector control (SLV)".
Extend the Deceleration Time (F003/F203/
A093/A293).
Turn OFF the AVR Selection (A081/A281).
Use a Braking Resistor or Regenerative
Braking Unit.
Set Selection of Operation on Digital
