Zero Mark Emulation (Sinamics Mode) - Siemens SINAMICS S120 Function Manual

7.24.3

Zero mark emulation (SINAMICS mode)

The referencing mode set for the leading encoder is used to determine the zero mark
position for the zero mark emulation of the TM41.
Possible referencing modes are:
● Referencing to the zero position of the encoder
– Encoder zero mark of an incremental encoder
– Zero passage of the singleturn position of an absolute encoder
– Pole pitch of the resolver
● Referencing to the zero position of the encoder with selection of the correct zero position
using a BERO switching signal (CU parameter p0493)
● Referencing to an external zero mark connected via an input terminal (CU parameter
p0495)
Note
Original encoder with several zero marks
If the original encoder (leading encoder) has several zero marks/positions, an additional
condition (BERO signal) must be selected for the required zero mark.
Adjustable zero mark offset at the TM41 output
An offset of the pulse grid can be set for the the zero mark position of the encoder emulation
using p4426.
