2.3 FB13 "Drive_FB"
The FB coordinates the cyclic process data transfer between the PLC and the
respective drive (SERVO) of the SINAMICS S120 on the basis of the extended
default frame 1. This requires the drive (STARTER) as well as the controller
(STEP 7, HW Config) to be configured with default frame 1 extended by the alarm
and error code.
With the extended default frame 1 the following data is exchanged:
