3.2.37 Gearbox compensation (GEARCOMP)

Purpose

Compensates elasticities in the drive train (e.g. gearbox torsion).

Implementation of an adaptive linkage of e.g. the phase setpoint (32 bits) and the torque feedforward

control (14 bits).

GEARCOMP−OUT ph − − − − Outputs the compensated phase setpoint.

Function

l The signal at GEARCOMP−TORQUE is broken down into the absolute value and the sign.

– The absolute value is limited to 2

(+16384) first.

l The absolute value is converted (via C1260, C1261, C1262).

l The result is evaluated with the sign and is added to the signal at GEARCOMP−PHI−IN.
