Inputs
Outputs
Source: DriveLib – Siemens: Post ID: 109475044
Version dated 10/2021
Hardware ID for LAddr: The hardware ID of the drive must be assigned to the
LAddr input.
REQ activates the read block, then the value appears in Value.
The
Write
action first reads the parameter value and format of the set para-
meter from the variable frequency drive and writes it to the parameter struc-
ture. After successful reading, the parameter value of the corresponding job
field set by the user is then transferred to the variable frequency drive.
During this process, the Busy bit is set to 1.
The
Read
action reads the parameter value and format of the set parameter
from the SINAMICS drive and writes it to the parameter structure. The value
of the corresponding job field to be read is then stored in the structure.
