Communication via SINAMICS Link
6.9.1
Basic principles of SINAMICS Link
SINAMICS Link allows data to be directly exchanged between a maximum of 64 Control
Units (CU320-2 PN and CU320-2 DP). The participating Control Units must be equipped with
the CBE20 supplementary module. Other nodes cannot be integrated into this
communication.
Possible applications include e.g.:
● Torque distribution for n drives
● Setpoint cascading for n drives
● Load distribution of drives coupled through a material web
● Master/slave function for infeed units
Preconditions
The following preconditions must be fulfilled to operate SINAMICS Link:
● r0108.31: Function module "PROFINET CBE20" must be activated.
● r2064[1]: The bus cycle time (T
dp
) must be an integer multiple of p0115[0] (current
controller cycle).
● r2064[2]: The master cycle time (T
mapc
) must be an integer multiple of p0115[1] (speed
control cycle).
● p0115[0]: The current controller clock cycle must be set to 250 µs or 500 µs. One clock
cycle with 400 µs is not permitted. For 400 μs, alarm A01902 is output with alarm value
"4". As countermeasure, set the current controller cycle with p0115[0] to 500 µs.
