Conditions
Condition for using the function:
ƒ The basic device must be equipped with a communication module
E94AYCPM (PROFIBUS-DP), SW version 0.9 and connected to the
PROFIBUS.
ƒ The basic device must receive PROFIBUS data telegrams from a master
controller.
Danger!
If the request for the safety function is cancelled, the drive will
restart automatically.
You must provide external measures which ensure that the drive
only restarts after a confirmation (EN 60204).
1.3.4.3
Settings
This function does not have any parameters to be set.
Permanently set parameters:
ƒ The stopping time amounts to t
s
= 30 s.
Tip!
In many applications the stopping time is < 30 s. Thus STO is
already activated and the SS1 function is stopped when ”0”
speed is reached.
In order to determine the maximum response time consider the
stopping time (30 s).
This time can only be reduced by setting the STO function
through the safe control after the application-specific stopping
time.
1.3.4.4
Activation
How to activate the function:
ƒ A PROFIBUS data telegram with corresponding PROFIsafe contents is
transmitted to the basic device ( 1.3-12).
