Torque Boost #1

Parameter Type — Numerical

The Motor #1 Torque Boost function is used to increase the low frequency

Factory Default — (ASD-dependent)

 

torque for high-inertia loads by increasing the output voltage at frequencies

Changeable During Run — Yes

below ½ of the #1 Base Frequency setting.

 

The value programmed as a boost percentage establishes an output voltage vs.

smoother operation.

 

 

 

 

 

 

 

 

 

 

 

 

Units — %

Note: Setting an excessive Torque Boost level may cause nuisance

 

tripping and mechanical stress to loads.
