Torque Boost
Manual Torque Boost
Manual torque boost increases the output voltage during motor starting and low speed operation.
Increase the boost percentage to improve motor starting properties for loads that require high
starting torque.

Code Description
dr.16 Fwd Boost Set torque boost for forward operation.
dr.17 Rev Boost Set torque boost for reverse operation.
Excessive torque boost will result in over-excitation, motor overheating and possible over current
faults .
Auto Torque Boost-1
Auto torque boost enables the inverter to automatically calculate the amount of output voltage
required for torque boost based on the entered motor parameters. Because auto torque boost
requires motor-related parameters such as stator resistance, inductance, and no-load current, auto
tuning (bA.20) has to be performed before auto torque boost can be configured [Refer to 5.9
on
page 143 ]. Configure auto torque boost for loads that require high starting torque.
