 Select F50 – [Electronic thermal select] to 1.
 It activates when the motor is overheated (time-inverse). If current greater than set in F51
flows, inverter output is turned off for the preset time in F51- [Electronic thermal level for 1
minute].
 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 an inductance motor, cooling effects decrease when a motor is running at low speed.
A special motor is a motor that uses a separately powered cooling fan maximize cooling effect
even in low speed.
