Standard Duty, Variable Torque Rating: The standard duty, variable torque rating allows overloads of 110% for 60 seconds. For most fan and pump applications, energy savings can be optimized by setting the V/Hz pattern to squared.

Standard Duty Rating, Constant Torque Rating: The standard duty, constant torque rating allows overloads of 120% for 60 seconds. Torque can be maintained by setting the V/Hz pattern to linear.

Heavy Duty, Constant Torque Rating: Heavy duty ratings provide a more robust power section for loads requiring higher starting torque and higher peak overloads of 150% for 60 seconds.
