This function is also usedto save and clear trip records.Alarms Stall prevention, overvoltage, overload, under-voltage, setting error, retry in process, upper/lower limitsCauses of failures Over-current, overvoltage, overheat, short-circuit in load, ground fault, overload on inverter, over-current througharm at start-up, over-current through load at start-up, CPU fault, EEPROM fault, RAM fault, ROM fault,communication error. (Selectable: emergency stop, under-voltage, small current, over-torque, motor overload, inputphase loss, output phase loss)Monitoring function Operation frequency, operation frequency command, forward/reverse run, output current, input voltage, outputvoltage, torque, torque current, load factor of inverter, input power, output power, information on input terminals,information on output terminals, version of CPU1, version of CPU2, PID feedback value, frequency command (aftercompensation), causes of past trips 1 to 4, parts replacement alarm, cumulative operation timePast trip monitoringfunctionStores data on the past four trips: number of trips that occurred in succession, operation frequency, direction ofrotation, load current, input voltage, output voltage, information on input terminals, information on output terminals,and cumulative operation time when each trip occurred.Output for frequencymeterAnalog output for motor: 1 mA dc full-scale dc ammeter0 - 20 mA (4 to 20 mA) output: DC ammeter (allowable load resistance: Less than 750 Ω)0 - 10 V output: DC voltmeter (allowable load resistance: Over 1 kΩ)Resolution: Maximum of 1/2554-digit 7-segments LED Frequency: inverter output frequency.Alarm: stall alarm “C”, overvoltage alarm “P”, overload alarm “L”, overheat alarm “H”.Status: inverter status (frequency, cause of activation of protective function, input/output voltage, outputcurrent, etc.) and parameter settings.Free-unit display: arbitrary unit (e.g. rotating speed) corresponding to output frequency.Display functionIndicator Lamps indicating the inverter status by lighting, such as RUN lamp, MON lamp, PRG lamp, % lamp, Hz lamp. Thecharge lamp indicates that the main circuit capacitors are electrically charged.Location of use Indoors; not exposed to direct sunlight, corrosive gas, explosive gas, flammable gas, oil mist, or dust; and vibrationof less than 5.9 m/s2 (10 to 55 Hz).Elevation 3000 m or less (current reduction required over 1000 m) Note 4)Ambient temperature -10 to +60°C Note)1.2.Storage temperature -25 to +70°CEnvironmentsRelative humidity 5 to 95% (free from condensation and vapor).Note 1. Above 40°C : Remove the protective seal from the top of VF-nC3.If the ambient temperature is above 50°C: Remove the seal from the top of the inverter and use the inverter with therated output current reduced.Note 2. If inverters are installed side by side (with no sufficient space left between them): Remove the seal from the top ofeach inverter.When installing the inverter where the ambient temperature will rise above 40°C, remove the seal from the top of theinverter and use the inverter with the rated output current reduced.Note 3 For a side-by-side installation, remove the seal on top. However, in areas where the ambient temperature exceeds40°C, remove the seal on top and reduce the rated output current. (See 6.11 in E6581595.)Note 4 Current must be reduced by 1% for each 100 m over 1000 m. For example, 90% at 2000 m and 80% at 3000 m.efesotomasyon.com -Toshiba inverter,drive,servo,plc
