Torque Boost

Compensates for the voltage drop caused by the resistance in the 1st resistance of the motor,
or by wiring to suppress torque reduction at a low speed range.
To select the automatic torque boost for A041/A241, set Motor Capacity (H003/H203) and
Motor Pole Number (H004/H204) according to your motor.

Manual Torque Boost
Outputs the voltage set in A042/A242 or A043/A243.
In A042/A242, set a ratio based on the voltage set in the motor voltage selection as 100%. The
ratio set here corresponds to the output frequency of 0 Hz.
If you raise the set value of the manual torque boost, be careful about motor overexcitation.
Otherwise, the motor may burn out.
The Manual Torque Boost Frequency A043/A243 is set in percentage terms based on the base
frequency as 100%.
Switch between Controls 1/2 using the SET terminal which is a multi-function input terminal to
which "08: SET" is allocated.
