		Output voltage adjustment	Main circuit voltage feedback control. (Switchable between automatic adjustment/fix/control off)
		Output frequency range	Setting between 0.01 to 500Hz. Default max. frequency is set to 0.01 to 60Hz.
			Maximum frequency adjustment (30 to 500Hz)
		Minimum setting steps of	0.01Hz: operation panel input (60Hz base),
		frequency	0.02Hz: analog input (60Hz base, 11 bit/0 to 10Vdc)
		Frequency accuracy	Analog input: ±0.2% of the maximum output frequency (at 25±10°C)
	specification		Digital input: ±0.01%±0.022Hz of the output frequency
		Voltage/frequency	V/f constant, square reduction torque control, automatic torque boost, vector calculation control, base
			frequency adjustment 1 and 2 (25 to 500Hz), V/f 5-point arbitrary setting, torque boost adjustment (0 to
		characteristics
			30%), start frequency adjustment (0 to 10Hz), stop frequency adjustment (0 to 30Hz)
	Control		3kΩ potentiometer (possible to connect to 1 to 10kΩ-rated potentiometer)
		Frequency setting signal	0 to 10Vdc (input impedance Zin: 30kΩ)
			0 to ±10Vdc (Zin: 22kΩ)
			4 to 20mAdc (Zin:242Ω)
		Terminal board base	The characteristic can be set arbitrarily by two-point setting. Compliant with 6 types of input; analog input
		frequency	(RR, VI/II, RX, RX2), pulse input and binary/BCD input (*RX2, binary/BCD input: optional)
		Frequency jump	3 places. Setting of jump frequency and width.
		Upper and lower limit	Upper limit frequency: 0 to max. frequency, lower limit frequency: 0 to upper limit frequency
		frequencies
		PWM carrier frequency	Adjustable between 1.0 to 16kHz.
		PID control	Adjustment of proportional gain, integral time, differential time and delay filter
		Acceleration/deceleration	0.01 to 6000 sec. Selectable from among acceleration/deceleration. times 1 and 2. Automatic
		time	acceleration/deceleration function. S-pattern acceleration/deceleration 1 and 2 pattern adjustable.
		DC braking	Adjustment of braking start frequency (0 to 120Hz), braking (0 to 100%) and braking time (0 to 20 sec.).
			With emergency stop braking function and motor shaft fix control function.
		Forward run/reverse run	With F-CC closed to forward run, with R-CC closed to reverse run, with both closed to reverse run. With
		[Note 1]	ST-CC opened to coast stop. Emergency stop by panel operation or terminal board.
		Jog run	Jog mode, if selected, allows jog operation from the operation panel
		[Note 1]	Jog run operation by terminal board is possible by setting the parameters.
	specifications	Preset speed operation	By changing the combination of open/close between S1, S2, S3, RR/S4-CC, set frequency + 15-speed
			operation.
		[Note 1]
			Selectable between acceleration/deceleration time, torque limit and V/f by set frequency.
		Retry	Capable of restarting after a check of the main circuit elements in case the protective function is
			activated. Max. 10 times selectable arbitrarily. Waiting time adjustment (0 to 10 sec.)
	Operation	Soft stall	Automatic load reduction control at overloading. (Default: OFF)
		Operation panel key	Key prohibition selectable for frequency setting, etc. All key operations can also be prohibited.
		Cooling fan ON/OFF	The cooling fan will be stopped automatically to assure long life when unnecessary.
			However, the fan inside the drive will always runs.
		operation ON/OFF control
		Regenerative power	Possible to keep the motor running using its regenerative energy in case of a momentary power failure.
		ride-through control	(Default: OFF)
		Auto-restart operation	Possible to restart the motor in coasting in accordance with its speed and direction. (Default: OFF)
		Commercial inverter	Possible to switch operation by commercial power source or inverter
		switching
		Drooping function	When two or more inverters are used to operate a single load, this function prevents load from
			concentrating on one inverter due to unbalance.
10		Override function	External input signal adjustment is possible to the operation frequency command value.
	function		Stall prevention, current limit, overcurrent, overvoltage, short circuit on the load side, ground fault on the
		Protective function	load side [Note 5], undervoltage, momentary power failure (15ms or more), non-stop control at
			momentary power failure, overload protection, arm overload at starting, overcurrent on the load side at
	Protective		starting, overcurrent and overload at dynamic braking resistance, fin overheat, emergency stop
		Electronic thermal	Reset by 1a contact closed (or 1b contact opened), or by operation panel. Or power source OFF/ON.
			Switchable between standard motor/constant torque VF motor, adjustment of overload protection and
		characteristic	stall prevention level.
		Reset	This function is also used to save and clear trip records.
