N300 INSTRUCTION MANUAL

Torque boost

A correctly installed motor and careful attention to voltage
drop in the wiring will improve the motor torque at low speed.
Setting of A041/A241 will select between manual torque
boost and automatic torque boost, the level of torque boost
corresponds to the set motor capacity selection (H003/H203)
and the motor pole selection (H004/H204).

(1) Manual torque boost
The values set up with A042/A242/A342 and A043/A243/A343 is outputted.
A042/A242/A342 sets a percentage level where the base frequency voltage is 100%.
The level set is the value of torque boost output voltage at 0Hz.
When using the manual torque boost, it should be noted that overuse will cause saturation of the motor and
may cause damage.
The manual torque boost break point is the frequency at which the voltage torgue boost is switched off and
normal operation resumes.
To change of A041,A042,A043/A241,A242,A243/A342,A343 an intelligent input needs to be set to 08(SET)/
17(SET3) and switched on.

(2) Automatic torque boost

The output voltage is adjusted automatically by condition of the load.
When using automatic torque boost it important that the following two parameters art correctly.
In case of adding over-current protection at deceleration time, set AVR selection ON all the time.
