Restrictions for Safety Integrated Extended Functions "without encoder"
The following restrictions apply for the Safety Extended Functions "without encoder":
Only operation with motors of type
1 SIEMOSYN
No operation for units with the following design
1 Blocksize GX
2 Chassis
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)
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)
1)
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)
2 The permissible ramp time is a minimum of 1 second for synchronous motors (the ramp
time depends on the power rating)
3 Current controller cycle of 32.5 µs result in a fault in the Motor Module
3)
2)
Note: For a cycle "0 → +n
set
→ -n
set
→ 0, a minimum period of 2 s is required.
2)
Note: This means that a current controller cycle of 62.5 µs on a double-axis Motor Module with 2
Safety axes is also not possible.
