WXU : Auto-restart control selection
Warning
Mandatory
• Do not go near motors and equipment.
Motors and equipment that have stopped temporarily after momentary power failure will restart
suddenly after recovery. This could result in unexpected injury.
• Attach warnings about sudden restart after a momentary power failure on inverters, motors and
equipment for prevention of accidents in advance.
•Function
Auto-restart detect the rotating speed and direction of rotation of the motor during coasting or momentary
power failure, to ensure that the motor restarts smoothly (Motor speed search function). This parameter also
allows commercial power operation to be switched to inverter operation without stopping the motor.
During operation, “TVT[” is displayed.
