Toshiba VF-nC1 Preset speed operation speeds in 15 steps, Motor 150%-overload time limit H

E6581090

■Motor 150%-overload time limit : H

Using the H parameter (motor 150%-overload withstanding time), you can set the time (between 10 and 800 seconds) elapsed before an overload trip occurs (QN) when the motor is operated under a load of 150%.

Title	Function	Adjustment range	Default setting
H	Motor 150%-overload time limit	10～800 (sec)	300

5.11Preset speed operation (speeds in 15 steps)

UT ～ UT : Preset speed operation frequencies 1~7 (Hz)

H ～ H : Preset speed operation frequencies 8~15

• Function
	A maximum of 15 speed steps can be selected just by switching an external contact signal.										5
	Multi-speed frequencies can be programmed anywhere from the lower limit frequency NN
	to the upper limit frequency WN.
[Setting method]
1) Run/stop
	The starting and stopping control is done from the terminal board.
	Title			Function		Adjustment range		Default setting		Setting
EOQF			Command mode			0: Terminal board		1		0
			selection			1: Operation panel
Note: If speed commands (analog signal or digital input) are switched in line with preset speed
	operations, select the terminal board using the frequency setting mode selection HOQF.
									⇒ See 3) or 5.1
2) Preset speed frequency setting
	Set the speed (frequency) of the number of steps necessary.
	Setting from speed 1 to speed 7
