7.6 Extended torque control (kT estimator, servo)
The "extended torque control" function module comprises two modules - the k
the compensation of the voltage emulation error of the drive converter. As a consequence,
the torque accuracy is 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
● k
● Compensation of the voltage emulation error of the drive converter (p1952, p1953)
● Configuration via p1780
