Safety Integrated Functions

8.5 Safety Integrated Extended Functions

Function Manual

366 Function Manual, 06/2012, 6SL3097-4AB10-0BP4

Technological restrictions

1 Pulling loads are not permitted

2 The slip of an induction motor must be taken into account

No operation in conjunction with the following functions

1 Flying restart

2 Current limitation I

lim

3 DC brake

4 Compound brake

5 SW pulse logic

6 Motor identification

7 Motor data set changeover of synchronous and induction motors is not permitted

8 Pulse pattern technique for encoderless vector control of synchronous motors (selected

using p1750.5)

Note: Activation of a Safety motion monitoring function and simultaneously using these drive

functions results in a Safety fault.

Performance restrictions

1 Within1 s only one start-up and one down-ramp are permitted

2 The permissible ramp time is a minimum of 1 second for synchronous motors (the ramp

time depends on the power rating)

Note: For a cycle "0 → +n

set

→ -n

set

→ 0, a minimum period of 2 s is required.

CAUTION

Safety Integrated Extended Functions "without encoder" must not be used if the motor,

after it has been switched off, can still be accelerated by the mechanical elements of the

connected machine component.

Whether or not a mechanical brake is installed is irrelevant here.
