Important
• At restart, it takes about 1 second for the inverter to check the motor speed. For this reason, the
startup takes more time than usual.
• Use this function when operating a system with one motor connected to one inverter. This
function may not operate properly in a system configuration when multiple motors are
connected to one inverter.
• When using this parameter, do not set <F605: Output phase loss detection> to "1", "2", or "4".
For details, refer to [6. 30. 5].
• Do not apply it for cranes.
The load may be lowered during waiting time from input of the run command to startup. To
apply the inverter to cranes, therefore, set <F301: Auto-restart> to "0: Disabled". Do not use the
retry function, either.
• This function is always enabled at torque control. (independent to <F301> setting)
Memo
• When the motor is restarted from retry, this function is operated regardless of the setting of this
parameter.
• It is not malfunction that abnormal noise might be heard from the motor during the motor speed
search at the auto-restart.
