All TN drives have these three motor-side controls as standard

MOTOR SIDE

SCALAR CONTROL(V/Hz)

Basic speed control forapplications such asFANS, PUMPS where ahigh level of speed andtorque are not required.

SENSORLESS VECTORCONTROL (SLS)

Used for more accurate torqueand speed performance whentheir dynamic control is not afundamental requirement. Forapplications such asEXTRUDERS, MIXERS, KILNS,LARGE PUMPS AND FANS.

FIELD ORIENTATED VECTORCONTROL (FOC)shaft encoder (required option)

Required for high dynamicperformance. Brings together highspeed accuracy, torque controlacross the whole speed range usinga closed torque control loop (i.e.tension regulators, winders, pay-offreels, position regulators, etc)
