Speed Control (S); Speed Limit - Siemens SIMOTICS S-1FL6 Operating Instructions Manual

Control functions

7.3 Speed control (S)

Note
Be sure to perform the "ABS" function again after you set p29243 to 1.
Virtual multiturn encoder (p29244)
With a rotary absolute encoder with activated position tracking (p29243 = 1), p29244 can be
used to enter a virtual multiturn resolution. This enables you to generate a virtual multiturn
encoder value from a singleturn encoder.
Overview of important parameters
• p29243
• p29244
• p29248
• p29249

Speed limit

Two sources in total are available for the speed limit. You can select one of them via a
combination of digital input signal SLIM:
Digital signal (SLIM)
Note
The bit 0 of parameter p29108 must be set to 1 to enable the speed limit function.
Note
You can switch between the two sources and modify their values when the servo drive is
running.
