5.13.1 Manual torque boost
V/F V/F V/F
Voltage drop in the low-frequency range can be compensated, improving reduction of the motor torque in the low-speed range.
• Motor torque in the low-frequency range can be adjusted according to the load, increasing the motor torque at the start up.
• By using the RT signal, it is possible to switch between 2 types of torque boost.
