5.2.1 General information on the ”speed setpoint” mode
Description
5 Description of the Functions
For operation with a DP master, a speed setpoint can be cyclically input
into the POSMO A 75 W / 300 W drives via PROFIBUS DP. The speed
actual value is also cyclically fed back via PROFIBUS DP.
The ”speed setpoint” mode is activated via P700 = 1 and de–activated
via P700 = 2; however, only power–on is effective.
The active operating mode is displayed in P930.
If the factory pre–setting is downloaded, then the ”speed setpoint”
mode is immediately de–activated and the system goes into the ”positioning”
mode.
Note
Before changing the operating mode, the factory pre–setting should be
downloaded using P970. This allows a defined initial status to be
achieved.
Reader’s note
Closed–loop control structure for the speed setpoint interface, refer to
Chapter 3.3.2.
