SINAMICS HLA and Safety Integrated
SINAMICS HLA supports the following Safety Integrated functions:
● Basic Functions
These functions are part of the standard scope of the drive and can be used without
requiring an additional license. These functions are always available. These functions do
not require an encoder and/or do not place any special requirements on the encoder
used.
– Safe Torque Off (STO)
– Safe Stop 1 (SS1, time-controlled)
● Extended Functions
Note
Only Safety Integrated with encoder is possible
SINAMICS HLA only supports Safety Integrated Extended Functions with encoder.
These functions require an additional safety license. Extended Functions with encoder
require an encoder with safety capability.
Note
Encoder types for SINAMICS HLA
The following encoder types are permissible for SINAMICS HLA:
• Single-encoder systems
• 2-encoder systems

Safe Torque Off is a safety function that prevents the drive from restarting
unexpectedly, in accordance with EN 60204-1. STO prevents the supply of energy to
the valve which can generate a force and corresponds to Stop Category 0.
Safe Stop 1 is based on the "Safe Torque Off" function. This means that a Category 1
stop in accordance with EN 60204-1 can be implemented.
– DRIVE-CLiQ encoder with safety capability
– sin/cos encoder connected via SME20/25, SME120/125 or SMC20 (1Vss, pure
analog signal processing)
– Encoders with DRIVE-CLiQ connection
– sin/cos encoder connected via SME20/25, SME120/125 or SMC20 (1Vss, pure
analog signal processing)
– HTL/TTL encoder connected via SMC30 (not in connection with SINUMERIK)
– TTL encoder connected via the onboard interface of the HLA module (not in
connection with SINUMERIK)
