Function

l

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

– The absolute value is limited to 2

14

(+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.
