Item		Specification
Principal control functions	Control system	Sinusoidal PWM control
	Related output voltage	Adjustable of output voltage in base freguency setting by the correcting supply voltage (200V) (Unadjustable to any voltage higher than the input voltage).
	Output frequency range	0.5 to 200Hz, default setting: 0.5 to 80Hz, maximum frequency: 30 to 200Hz.
	Minimum setting steps of frequency	0.1Hz: operation panel setting, 0.2Hz: analog input (when the max. frequency is 100Hz).
	Frequency accuracy	Digital setting: within +/-0.5% of the max. frequency (-10 to +50 degreeC) Analog setting: within +/-1.0% of the max. frequency (25 degreeC +/- 10 degreeC)
	Voltage/frequency characteristics	V/f, sensorless vector control, base frequency, base frequency voltage and torque boost amount adjustable
	Frequency setting signal	Volume on the front panel, external frequency volume (connectable to a volume with a rated impedance of 3-10kohm), VI terminal (input impedance: 42kohm(voltage: 0-10Vdc) or 250ohm (current: 4-20mAdc)). The characteristic can be set arbitrarily by two-point setting.
Operation specifications	Start-up frequency/frequency jump	Adjustable within a range of 0.5 to 10Hz/Up to 1 frequency can be adjusted together with their widths.
	PWM carrier frequency	Selectable from among 2, 4, 8, 12 and 16kHz (Standard default setting: 12kHz)
	Acceleration/deceleration time	0.1 to 3000 seconds, switchable between acceleration/deceleration time 1 and 2.
	Retry operation	Number of times of retry selectable (Max. 10 times). If the protection function is activated, the retry function restarts on completion of a check of the main circuit.
	Electric control	Charging of capacitor (Deceleration time can be shortened by activating Forced Shortened Deceleration mode.)
	DC braking	Braking start-up frequency: 0 to maximum frequency, braking rate: 0 to 100%, braking time: 0 to 20 seconds.
	Input terminal functions (selectable)	Forward/reverse run input signal, jog run input signal, standby signal, preset-speed operation input signal, reset input signal, etc./Switching between sink/source.
	Output terminal functions (selectable)	Frequency lower limit output signal, frequency upper limit output signal, low-speed detection output signal, specified speed attainment output signal, etc. Open collector, RY output.
	Failure detection signal	1c-contact output: 250Vac/2A, cos = 0.4
	Output for frequency meter output for ammeter	PWM output: (1mAdc full-scale DC ammeter or 7.5Vdc full-scale DC ammeter/Rectifier-type AC voltmeter, 225% current Max. 1mAdc, 7.5Vdc full-scale)
Protective function	Protective function	Stall prevention, current limitation, over-current, output short circuit, over-voltage, over-voltage limitation, undervoltage, ground fault, power supply phase failure, output phase failure overload protection by electronic thermal function, armature over-load at start-up, load-side over-torque at start, overheating prevention, detection of analog signal break.
	Protection against momentary power failure	Auto-restart/non-stop control after momentary power failure.
	Electronic thermal characteristics	Switching between standard motor/constant-torque VF motor, overload trip, overload stall selection.
Display function	4-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, output current, etc.) and parameter settings. Free-unit display: arbitrary unit (e.g. rotating speed) corresponding to output frequency.
Display function	Indicator	Lamps indicating the inverter status by lighting, such as RUN lamp and PRG lamp.
Environments	Use environments	Indoor, altitude: 1000m (Max.), not exposed to direct sunlight, corrosive gas, explosive gas or vibration (less than 5.9m/s2) (10 to 55Hz).
	Ambient temperature	-10 to 50 degreeC Note)1.2
	Storage temperature	-20 to +65 degreeC
	Relative humidity	20 to 93% (free from condensation and vapor).

Note) 1. Above 40 degreeC: Remove the protective seal from the top of VF-nC1.
Note) 2. Side-by-side installation : 40 degreeC or less (Remove the protective seal from the top of VF-nC1).
