5.13Manual torque boost - increasing torque at low speeds

: Torque boost 1

• Function

If torque is inadequate at low speeds, increase torque by raising the torque boost rate with this parame- ter.

	Base frequency voltage
	Output voltage	[V]/(%)
			Base frequency	Output frequency (Hz)
[Parameters]
Title		Function	Adjustment range		Default setting
	Torque boost 1		0 ∼ 30 (%)		According to model
					(See section 11)

★ Valid for the standard default setting, = 0 (V/F constant) and 1 (variable torque).

Note 1: The optimum value is programmed for each inverter capacity. Be careful not to increase the torque boost rate too much because it could cause an overcurrent trip at startup. If you are going to change the set values, keep them within ± 2% of the standard default values.

5.14 Setting the electronic thermal

: Electronic thermal protection characteristic selection : Motor electronic thermal protection level 1

•Function

Selects the electronic thermal protection characteristics that fit with the ratings and characteristics of the

motor. This is the same parameter as the extended parameter . The set values will be the same no matter which one is changed.
