2.26  Limit speed 
Address    : D128 
Write authorisation  : ebm-papst 
This parameter defines the limit value for the safety function "limit speed". The closed-loop speed control in 
this safety function ensures that the limit speed for the impeller is not exceeded.

Note: 
The limit speed is not related to the maximum speed!

2 different characteristics can be defined. 
The "Internal parameter set" parameter is used to select whether the "Parameter set 1" values or the 
"Parameter set 2" values are applicable (see 2.13 Internal parameter set). 
These parameters are used to assign a set value to the voltage at the control input.
