For a speed–synchronous coupling, the drive accelerates after the cou-
pling has been switched–in, with the acceleration in P0103, up to the
speed of the master drive.
The following error, that is automatically obtained when the slave drive
accelerates due to the different output velocities, is no longer reduced
to zero.
The position difference of the two drives is constant in the synchronous
phase.
