Boosting Torque At Low Speeds - Panasonic VF0 Series 400V class Instruction Manual

Boosting Torque at Low Speeds

If a large torque is required at low speeds, increase the torque boost level
(parameter P05) setting data value to increase the output voltage and
thereby increase the torque.

If the boost level is too high, an overcurrent
fault, overload fault or motor overheating
could occur or the noise could increase.
The motor current will increase when the
boost level is increased.
Carefully consider the settings for the overload
function and overload current (parameters P06,
P07).
