Toshiba VF-S11 manual Common specification, Characteristics

E6581160

Note 1. Capacity is calculated at 220V for the 240V models, at 440V for the 500V models and at 575V for the 600V models. Note 2. Indicates rated output current setting when the PWM carrier frequency (parameter F300) is 4kHz or less. When

exceeding 4kHz, the rated output current setting is indicated in the parentheses. It needs to be further reduced for PWM carrier frequencies above 12 kHz.

The rated output current is reduced even further for 500V models with a supply voltage of 480V or more. The default setting of the PWM carrier frequency is 12kHz.

Note 3. Maximum output voltage is the same as the input voltage. Note 4. ±10% when the inverter is used continuously (load of 100%).

Note 5. If you are using 600V model, be sure to connect an input reactor (ACL).

		Analog setting: within ±0.5% of the max. frequency (25°C ±10°C)
	Voltage/frequency	V/f constant, variable torque, automatic torque boost, vector control, automatic energy-saving, dynamic automatic
control	characteristics	energy-saving control, PM motor control. Auto-tuning. Base frequency (25 - 500Hz) adjusting to 1 or 2, torque boost
		(0 - 30%) adjusting to 1 or 2, adjusting frequency at start (0.5 - 10Hz)
	Frequency setting signal	Potentiometer on the front panel, external frequency potentiometer (connectable to a potentiometer with a rated
Principal		impedance of 1 - 10kΩ), 0 - 10Vdc (input impedance: VIA/VIB=30kΩ, 4 - 20mAdc (Input impedance: 250Ω).
	Terminal board base	The characteristic can be set arbitrarily by two-point setting. Possible to set individually for three functions: analog
	frequency	input (VIA and VIB) and communication command.
	Frequency jump	Three frequencies can be set. Setting of the jump frequency and the range.
	Upper- and lower-limit	Upper-limit frequency: 0 to max. frequency, lower-limit frequency: 0 to upper-limit frequency
	frequencies		8
	PWM carrier frequency	Adjustable within a range of 2.0 to 16.0Hz (default: 12kHz).
	PID control	Setting of proportional gain, integral gain, differential gain and control wait time. Checking whether the amount of
		processing amount and the amount of feedback agree.
	Acceleration/deceleration	Selectable from among acceleration/deceleration times 1, 2 and 3 (0.0 to 3200 sec.). Automatic
	time	acceleration/deceleration function. S-pattern acceleration/deceleration 1 and 2 and S-pattern adjustable. Control of
		forced 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 20 seconds,
		emergency DC braking, motor shaft fixing control
	Dynamic braking	Control and drive circuit is built in the inverter with the braking resistor outside (optional).
	Input terminal function	Possible to select from among 66 functions, such as forward/reverse run signal input, jog run signal input, operation
	(programmable)	base signal input and reset signal input, to assign to 8 input terminals. Logic selectable between sink and source.
	Output terminal functions	Possible to select from among 58 functions, such as upper/lower limit frequency signal output, low speed detection
specifications	(programmable)	signal output, specified speed reach signal output and failure signal output, to assign to FL relay output, open
		collector output and RY output terminals.
	Jog run	Jog mode, if selected, allows jog operation from the operation panel or the terminal board.
	Forward/reverse run	The RUN and STOP keys on the operation panel are used to start and stop operation, respectively. The switching
		between forward run and reverse run can be done from one of the three control units: operation panel, terminal
		board and external control unit.
Operation	Preset speed operation	Base frequency + 15-speed operation possible by changing the combination of 4 contacts on the terminal board.
	Various prohibition	Possible to write-protect parameters and to prohibit the change of panel frequency settings and the use of operation
	Retry operation	Capable of restarting automatically after a check of the main circuit elements in case the protective function is
		activated. 10 times (Max.) (selectable with a parameter)
	settings	panel for operation, emergency stop or resetting.
	Regenerative power ride-	Possible to keep the motor running using its regenerative energy in case of a momentary power failure (default:
	through control	OFF).
	Auto-restart operation	In the event of a momentary power failure, the inverter reads the rotational speed of the coasting motor and outputs
		a frequency appropriate to the rotational speed in order to restart the motor smoothly. This function can also be
		used when switching to commercial power.
	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	The sum of two analog signals (VIA/VIB) can be used as a frequency command value.
	Failure detection signal	1c-contact output: (250Vac-0.5A-cosφ=0.4)
