2) Inverter over load characteristics

Set to protect the inverter unit. Cannot be changed or turned off by parameter setting.

If the inverter overload trip function ( ) is activated frequently, this can be improved by adjusting the

stall operation level downward or increasing the acceleration time or deceleration time .

Inverter overload

Time [s]

100%: inverter rated output current

			Output current [%]

5			* To protect the inverter, overload trip may activate in a short period of time when output
			current reaches 150% or higher.

		5.15 Preset-speed operation (speeds in 15 steps)

		∼	: Preset-speed operation frequencies 1~7
~			: Same as Sr1 ~ Sr7
		∼	: Preset-speed operation frequencies 8~15

• Function

A maximum of 15 speed steps can be selected just by switching an external contact signal. Multi-speed

frequencies can be programmed anywhere from the lower limit frequency to the upper limit frequency

.

[Setting method]

1)Run/stop

The starting and stopping control is done from the terminal board.

Title	Function	Adjustment range	Setting

	Command mode selection	0: Terminal board	1
