Important
• When the motor is operated in the inhibited direction during operations such as preset speed
operation with functions or jog run, the run command will be set to OFF.
• If the motor parameters are not set to the appropriate values when vector control or automatic
torque boost is set, the motor may run in the reverse direction at approximately the slip
frequency.
Set <F243: End frequency> to approximately the slip frequency.
