General technical specifications
Protective structure					IP20				IP00
Rated input voltage			Three phase 380 ~ 460V +/-10%,					50/60Hz +/-5%
Rated output voltage				Three phase 0 .. 380 ~ 460VAC
				(Corresponds to input voltage)
Output frequency range						0,1 ~ 400Hz
Operating principle			Sensorless Vector Control (SLV), PWM sine coded.
					Power amplifier: IGBT/IPM
Overload current capacity				150% during 60s (constant torque)
				115% during 30s (quadratically rising torque)
Frequency accuracy		Digital command: +/-0.01% of the maximum frequency
(at 25°C +/-10°C)		Analog command: +/-0.1% of the maximum frequency
V/F characteristics				V/F curves with constant and reduced torque;
				vector control without feedback;
				vector control with feedback (optional)
Autotuning			Automatic adaption to motor characteristics to make
					best use of the motor driven
AVR function				Automatic Voltage Regulation usable
Acceleration/Deceleration		2 times settable between 0.01 and 3000s (using digital remote
				control); linear, S-curve, U-curve
Starting torque				150% at 1Hz (constant torque)
Braking resistor		Models J300-055HFE4 and J300-075HFE4 have a built-in braking
		resistor. Braking torque approx. 50% to 60% of the rated torque
		using the built-in braking resistor (the rest of the J300- models have
		a braking torque of approx. 10% to 15% of the rated torque using
				braking with feedback to capacitor).
DC braking		Variable operating frequency, time, and braking force.
Frequency command		Digital command using the built-in digital operator keys.
		Analog 0–5V and 0–10V (input impedance 30kOhm) and
		4–20mA (input impedance 250Ohm); optional digital input
Intelligent digital inputs		8 inputs configurable as: Forward run, Reverse run, Free run mode,
		Reset, Jog, 7 multistage speed settings, Ext. DC braking, 2. Setting,

2.Stage accel/decel, External alarm, USP function, Software lock, frequency command from analog input O or OI, Motor poten-

tiometer, Motor free run, Factory setting, etc.

Outputs		Analog output current, output frequency, and torque.
	Transistor output with signals for frequency arrival, motor
			running, torque alarm; Alarm output
Other functions	Optimized acceleration and deceleration times using fuzzy logic,
	engergy saving mode,			electronic thermal,		jump frequency,
			upper/lower limits,		PID control, etc.
Protective functions	Overcurrent, overvoltage, undervoltage, overload, excessive
	temperature, ground fault, braking resistor overload, etc.
Directives and standards	CE-EMC directive in conjunction with optional radio noise
	filter and installation according to installation guidelines;
			CE low voltage directive
Operating environment		Ambient temperature: -10~50°C with constant torque
			and -10~40°C with quadratically rising torque.
	Humidity: 20-90% RH (non condensing); Installation altitude:
				1000m or less
