E6581611L-212Note 5. Required power supply capacity varies with the value of the power supply side inverter impedance (including those ofthe input reactor and cables). Common specificationItem SpecificationControl system Sinusoidal PWM controlOutput voltage rangeNote1)Adjustable within the range of 50 to 330V (240V class) and 50 to 660V (500V class) by correcting the supplyvoltageOutput frequency range 0.1 to 500.0Hz, default setting: 0.5 to 80Hz, maximum frequency: 30 to 500HzMinimum setting steps offrequency0.1Hz: analog input (when the max. frequency is 100Hz), 0.01Hz: Operation panel setting and communicationsetting.Frequency accuracy Digital setting: within ±0.01% of the max. frequency (-10 to +60°C)Analog setting: within ±0.5% of the max. frequency (25°C ±10°C)Voltage/frequencycharacteristicsV/f constant, variable torque, automatic torque boost, vector control, automatic energy-saving. dynamic automaticenergy-saving control (for fan and pump), PM motor control, V/F 5-point setting, Auto-tuning.

Possible to set: analog input (VIA, VIB, VIC).Frequency jump Three frequencies can be set. Setting of the jump frequency and the range.Upper- and lower-limitfrequenciesUpper-limit frequency: 0.5 to max. frequency, lower-limit frequency: 0 to upper-limit frequencyPWM carrier frequency Adjustable range of 2.0k to 16.0kHz (default: 12.0kHz).Principal control functionsPID control Setting of proportional gain, integral gain, differential gain and control waiting time. Checking whether the amount ofprocessing amount and the amount of feedback agree.Acceleration/decelerationtimeSelectable from among acceleration/deceleration times 1 & 2 & 3 (0.0 to 3600 sec.). Automaticacceleration/deceleration function. S-pattern acceleration/deceleration 1 & 2 and S-pattern adjustable. Control offorced rapid deceleration and dynamic rapid deceleration.DC braking Braking start-up frequency: 0 to maximum frequency, braking rate: 0 to 100%, braking time: 0 to 25.5 seconds,emergency DC braking, motor shaft fixing control.Dynamic Braking DriveCircuitControl and drive circuit is built in the inverter with the braking resistor outside (optional).Input terminal function(programmable)Possible to select from among about 110 functions, such as forward/reverse run signal input, jog run signal input,operation base signal input and reset signal input, to assign to 8 input terminals. Logic selectable between sink andsource.Output terminal functions(programmable)Possible to select from among about 150 functions, such as upper/lower limit frequency signal output, low speeddetection signal output, specified speed reach signal output and failure signal output, to assign to FL relay output,open collector output terminal, and RY output terminals.Forward/reverse run The RUN and STOP keys on the operation panel are used to start and stop operation, respectively.Forward/reverse run possible through communication and logic inputs from the terminal block.Jog run Jog mode, if selected, allows jog operation from the terminal block and also from remote keypad.Preset speed operation Frequency references + 15-speed operation possible by changing the combination of 4 contacts on the terminalblock.Retry operation Capable of restarting automatically after a check of the main circuit elements in case the protective function isactivated. 10 times (Max.) (selectable with a parameter)Various prohibition settings/ Password settingPossible to write-protect parameters and to prohibit the change of panel frequency settings and the use of operationpanel for operation, emergency stop or resetting. Possible to write-protect parameters by setting 4 digits passwordand terminal input.Regenerative power ride-through controlPossible to keep the motor running using its regenerative energy in case of a momentary power failure (default:OFF).Auto-restart operation In the event of a momentary power failure, the inverter reads the rotational speed of the coasting motor and outputsa frequency appropriate to the rotational speed in order to restart the motor smoothly. This function can also beused when switching to commercial power.Light-load high-speedoperationIncreases the operating efficiency of the machine by increasing the rotational speed of the motor when it is operatedunder light load.Drooping function When two or more inverters are used to operate a single load, this function prevents load from concentrating on oneinverter due to unbalance.Override function External input signal adjustment is possible to the operation frequency command value.Operation specificationsRelay output signal 1c- contact output and 1a- contact output Note2)Maximum switching capacity : 250Vac-2A , 30Vdc-2A (At resistive load cosΦ=1),250Vac-1A (cosΦ=0.4) , 30Vdc-1A (L/R=7ms)Minimum permissible load : 5Vdc-100mA, 24Vdc-5mA
