• Pr.46 Second torque boost is enabled when the RT signal is ON. To input the RT signal, set "3" in any parameter from
Pr.178 to Pr.189 (Input terminal function selection) to assign the function.
NOTE
• When torque is continuously regenerated as vertical lift load, it is effective to set the rated voltage in Pr.19 Base frequency
voltage to prevent trip due to current at regeneration.
