HLA: Safety Integrated Extended Functions

SINAMICS HLA and Safety Integrated
SINAMICS HLA supports the following Safety Integrated functions:
● The Safety Integrated Extended Functions require an additional Safety Extended license.
Extended Functions with encoder require an encoder with safety capability (see Chapter
"Notes regarding safe actual value sensing using an encoder system (Page 155)").
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 (STO)
– Safe Stop 1 (SS1, time and acceleration controlled)
– Safe Operating Stop (SOS)
– Safe Stop 2 (SS2)
30
– DRIVE-CLiQ encoder with safety capability
– sin/cos encoder connected via SME20/25, SME120/125 or SMC20 (1 V
analog signal processing)
– Encoders with DRIVE-CLiQ connection
– sin/cos encoder connected via SME20/25, SME120/125 or SMC20 (1 V
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)
Safe Torque Off is a safety function to avoid unexpected startup in accordance with
EN 60204-1.
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.
Safe Operating Stop provides protection against unwanted movements. The drive is in
closed-loop control mode and is not disconnected from the power supply.
Safe Stop 2 is used to safely brake the valve with a subsequent transition into the
"Safe Operating Stop" state (SOS). This means that a Category 2 stop in accordance
with EN 60204-1 can be implemented.
