• Note:
Default setting of PWM carrier frequency is 12kHz, but rated output current of rating label display at
4kHz.
6.12 Trip-less intensification
6.12.1 Auto-restart (Restart during coasting)
: Auto-restart control selection
Caution
Mandatory
• Stand clear of motors and mechanical equipment
If the motor stops due to a momentary power failure, the equipment will start suddenly when power is
restored. This could result in unexpected injury.
• Attach warnings about sudden restart after a momentary power failure on inverters, motors and equip-
ment to prevent accidents in advance.
• Function
The F301 parameter detects the rotating speed and rotational direction of the motor during coasting
in the event of momentary power failure, and then after power has been restored, restarts the motor
smoothly (motor speed search function). This parameter also allows commercial power operation to
be switched to inverter operation without stopping the motor.
During operation, " " is displayed.
