If current greater than set in F51flows, inverter output is turned off for the preset time in F51- [Electronic thermal level for 1minute]. F51: Enter the value of max current that is capable of flowing to the motor continuously for oneminute. 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 isused. 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 effecteven in low speed.F53[Motor type]01Standard motors having a cooling fan directlyconnected to the shaftSpecial motor that uses a separately poweredcooling fan.Current forcontinuous [%]100F53 = 195F53 = 265Freq [Hz]20 6010-1
