		PID control	Adjustment of proportional gain, integral time, differential time and delay filter
		Torque control	Voltage command input specification: DC 0 to ±10V
		Acceleration/deceleration	0.01 to 6000 sec. Selectable from among acceleration/deceleration. times 1, 2, 3 and 4. 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.
		Preset speed operation	By changing the combination of open/close between S1, S2, S3, RR/S4-CC, set frequency + 15-speed
			operation.
		[Note 1]
	Operation		Selectable between acceleration/deceleration time, torque limit and V/f by set frequency.
		Soft stall	Automatic load reduction control at overloading. (Default: OFF)
		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.)
	specifications
		Cooling fan ON/OFF	The cooling fan will be stopped automatically to assure long life when unnecessary.
		Operation panel key	Key prohibition selectable between STOP key only, MODE key only, etc. All key operations can be
		operation ON/OFF control	prohibited.
		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)
		Simplified pattern	Possible to select each 8 patterns in 2 groups from 15-speed operation frequency. Max. 16 types of
		operation	operation possible. Terminal board operation/repeat operation possible.
		Commercial inverter	Possible to switch operation by commercial power source or inverter
		switching
		Light-load high-speed	Increases the operating efficiency of the machine by increasing the rotational speed of the motor when it
		operation	is operated under light load.
		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.
		Override function	External input signal adjustment is possible to the operation frequency command value.
	Protective		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
				12
			starting, overcurrent and overload at dynamic braking resistance, overheat, emergency stop
	function	Electronic thermal	Switchable between standard motor/constant torque VF motor, adjustment of overload protection and
			Reset by 1a contact closed (or 1b contact opened), or by operation panel. Or power source OFF/ON.
		characteristic	stall prevention level.
		Reset	This function is also used to save and clear trip records.
