Mixed operation of control modes for SINAMICS Integrated

Mixed operation of control modes for SINAMICS Integrated
The mixed operation of servo control, vector control and U/f control is possible but is subject
to restrictions.
Permissible:
• The mixed operation of servo control and U/f control
• The mixed operation of vector control and U/f control
Not permitted:
• The mixed operation of servo control and vector control
Note the following permissible drive quantities for mixed operation.
Mixed operation of servo control and U/f control
In mixed operation of servo control and U/f control, a drive takes up exactly as much
computing power in servo control at 125 μs as two drives in U/f control at 500 μs. In
combination with the servo control, a maximum of 11 drives is permitted (1 servo control
plus 10 U/f controls).

Mixed operation of vector control and U/f control
In mixed operation of vector control and U/f control, a drive takes up exactly as much
computing power in vector control at 250 μs as two drives in U/f control at 500 μs. In
combination with the vector control, a maximum of 11 drives is permitted (1 vector control
plus 10 U/f controls).
