Select F50 – [Electronic thermal select] to 1.
It activates when the motor is overheated (time-inverse). If current is greater
than that set in F51, inverter output is turned off for the preset time in F51.
F51: Enter the value of max current that is capable of flowing to the motor
continuously for one minute. It is set in percent of motor rated current. The
value cannot be set lower than F52.
F52: Enter the amount of current for continuous operation. Normally motor rated
current is used. It cannot be set greater than F51.
F53: For a standard motor, cooling fans are equipped; however, cooling effects
can be achieved when a motor is running at low speed. A separately powered
cooling fan is used.
