7.7Extended torque control (kT estimator, Servo)

Description

The "extended torque control" function module comprises two modules - the kT estimator and the compensation of the voltage emulation error of the drive converter. This allows the torque accuracy to be increased.

Note

When this function module is activated, the maximum number of drives that can be controlled from a Control Unit is reduced by at least one drive.

Features

kT estimator (only for synchronous motors)

Compensation of the voltage emulation error of the drive converter (p1952, p1953)

Configuration via p1780

Commissioning via STARTER

The extended torque control can be activated via: Right-click the drive > Properties > Function Modules.
