Before torque can be determined, the motor stator resistance and number of pole pairs must be entered here. The base
stator resistance can be determined from the motor's rated voltage and current. Torque metering is intended for induction
motors only, and only positive torque is calculated. Please consult the motor specifications for the stator resistance and the
pole pairs.
The default unit for torque is the SI unit of Newton-meter (Nm). The torque unit is selectable to either Newton-meter or foot-
pound.
1 Nm = 0.738 ft·lb.

Detection of a motor overtorque condition, usually done to protect devices driven by the motor, can be set up here. The
assigned relay activates when the torque measured exceeds the specified level for the specified time duration.
