Siemens SINUMERIK 804D sl Function Manual

Detailed Description
2.3 Setpoint/actual-value system
Velocities, Setpoint/Actual-Value Systems, Closed-Loop Control (G2)
2-40 Function Manual, 08/2005 Edition, 6FC5397-0BP10-0BA0
Direct measuring system (DM) is on machine directly: Load-side encoder
Indirect measuring system (IM) is on motor indirectly: Motor-side encoder
Depending on the type of axis (linear axis, rotary axis) and the type of actual-value
acquisition (directly at the machine, indirectly at the motor), the following machine data must
be parameterized to calculate the actual-value resolution:

- = Does not apply to this combination
* The encoder on the motor side is a built-in encoder and, therefore, does not have a measuring gear unit.
The transmission ratio is always 1:1.
