Gearbox switchover without increased position tolerance
In order to switch over the gearbox stage, where no increased tolerance is required for the
crosswise comparison of the actual positions, proceed as follows:
● Set the new gearbox stage using bits 0 to 2 in byte 3 of S_STW2.
● The actual values are then synchronized once automatically. This synchronization is used
to compensate any possible difference that occurs between the position actual values of the
two monitoring channels as a result of the switchover operation.
● The new gearbox stage is then active.
